  • Description: Online version of original print edition of the Special Publication of the Rhodes University, Department of Ichthyology, No.1 , Ascomana gen. nov., based on A. eximia sp. nov. is described from a single 700mm leptocephalus collected off Cape Town. It displays the following characters which in combination distinguish it from known eel genera: — Jaws moderately produced, hyomandibula essentialy vertical, short postocular region, occipital crest present, slender upwardly-curved lower jaw, pectoral fin with very numerous rays (23-24); larva reaching at least 700mm, eye not telescopic, caudal not attenuated or rounded, very numerous teeth, intestine a straight tube, pigment mainly as a series of large melanophores along the ventral body wall from throat to vent. The new genus and species shows some resemblances to the nessorhamphid eels. An elongate (565mm) leptocephalus, also collected from off Cape Town (that is, in the locality of the Dana "giant" eel-larvae), is identified with Leptocephalus giganteus Castle and is the second undoubted specimen of this species.

  • Description: Online version of original print edition of the Special Publication of the Rhodes University, Department of Ichthyology, No. 2 , Specimens from the southeast African coast conform well in essential characters with those displayed in radiographs of Muraena tota cinerea Forsskål from the Red Sea. In contrast, Japanese specimens which have been assigned to M.cinereus have more precaudal vertebrae, a higher total number of vertebrae, more numerous dorsal rays, a broader interorbital and a larger eye. They should therefore be set aside as distinct from Forsskål’s species. An available name for these is possibly M.singaporensis (Bleeker, 1853) although insufficient is known about M.cinereus - type eels in the Indo-Malayan region for this name to be confidently applied to the Japanese form. In many features western Indian Ocean M.cinereus closely resembles M.yamaguchiensis Katayama & Takai, 1954, also from Japan.

  • Description: This study describes the preparation, characterization and evaluation of new composite membranes with embedded dendrimer hosts and Fe/Ni nanoparticles. These new reactive membranes consist of films of cyclodextrin–poly(propyleneimine) dendrimers (β-CD–PPI) that are deposited onto commercial polysulfone microporous supports and crosslinked with trimesoyl chloride (TMC). The membranes were subsequently loaded with Fe/Ni nanoparticles and evaluated as separation/reactive media in aqueous solutions using 2,4,6-trichlorophenol as model pollutant. The morphology and physicochemical properties of the composite membranes were characterised using high-resolution transmission electron microscopy (HR-TEM), atomic force microscopy and measurements of contact angle, water intake, porosity and water permeability. The sorption capacity and catalytic activity of the membranes were evaluated using ion chromatography, atmospheric pressure chemical ionisation-mass spectrometry and UV–Vis spectroscopy (UV–Vis). The sizes of the embedded Fe/Ni nanoparticles in the membranes ranged from 40 to 66 nm as confirmed by HR-TEM. The reaction rates for the dechlorination of 2,4,6-trichlorophenol ranged from 0.00148 to 0.00250 min−1. In all cases, we found that the reaction by-products consisted of chloride ions and mixtures of compounds including phenol (m/z = 93), 2,4-dichlorophenol (m/z = 163) and 4-chlorophenol (m/z = 128). The overall results of this study suggest that β-CD–PPI dendrimers are promising building blocks for the synthesis of composite and reactive membranes for the efficient removal of chlorinated organic pollutants from water.

  • Description: Online version of original print edition of the Special Publication of the Rhodes University, Department of Ichthyology, No. 3 , An examination of vertebral numbers in a series of eels of the genus Moringua Gray, 1831 from the western Indian Ocean clearly indicates three species, with about 105—113, 115—125 and 153—160 vertebrae respectively. These counts are matched by proportionately shorter head and greater slenderness of body, which are not correlated with total length in each group. Lateral line pore counts and position of heart confirm the presence of three species. A study of the moringuid literature and of certain type material shows that the names Moringua microchir Bleeker, M.ferruginea Bliss and M.javanica (Kaup) may be applied to these. Aphthalmichthys abbreviatus Bleeker is almost certainly based on immature females of M.microchir and is considered a synonym. A vertebral count on the holotype of M.bicolor Kaup suggests that it may be the male form of M.javanica. Aphthal— michthys macrocephalus Bleeker is probably a synonym of M.macrochir Bleeker and the latter shows close similarities to M.raitaborua Hamilton—Buchanan. Growth in moringuids appears to be most rapid at a point a few segments in advance of the vent.

  • Description: War is a condition of this world. From man to the smallest insect, all are at strife, yet man has a "quality which makes him overlord of all; for whereas the creatures of the forest and plain kill only to eat, or to lead the herd ... man will kill for no reason at all. This makes him terrible among the creatures, for he is the very God of Destruction. And from man's pride in his weapons that give him power has grown his art." Warfare in its primeval state is a direct result of a natural phenomenon, springing from the discovery that certain grass seeds could be cultivated and that certain grass feeding animals could be domesticated. From these roots sprouted two very differently organised communities, the agricultural and the pastoral, who clashed for the first time in the third millenium B.C. , Thesis (MFA) -- Faculty of Humanities, Fine Art, 1968

  • Description: Online version of original print edition of the Special Publication of the Rhodes University, Department of Ichthyology, No. 4 , A commercial haul off the Limpopo River mouth in 260 - 270 fathoms collected 35 eels of the genus Bathymyrus Alcock, 1889, described here as B. smithi sp. nov. This has a shorter head and pectoral and a more posterior dorsal origin relative to the pectoral fin than in B.echinorhynchus Alcock, 1889 from the Bay of Bengal and B.simus Smith, 1965 from the South China Sea. B.smithi is also distinct in having extra-oral rostral teeth present but less conspicuously developed, more numerous vertebrae (150 — 155, compared with about 125 — 130 in the other species) and drab coloration. An osteological study shows that, although it has certain unique features, B.smithi is very closely similar to congrids of the subfamily Anagoinae. There are valid reasons for using the term Bathymyrinae for this group of congrid eels.

  • Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 5 , Two hauls made in late January, 1930 off southern Africa by the Danish Dana Expedition contained developing eggs and very young larvae of the congrid eel Gnathophis capensis (Kaup, 1856). Collection of these specimens confirms the suggestion made from previous larval studies that spawning, development, and at least early larval growth of this species occurs in late summer in this area.

  • Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 6 , Eight juvenile eels collected off southern Mozambique by the Galathea and identified as Congrina guttulata (Gunther, 1887) each have three well-defined, longitudinal rows of melanophores on the lateral body surface. The Dana collection of leptocephali contains many East African larvae with identical pigmentation. Their added close agreement in number of myomeres, fin-rays etc. allows such larvae to be firmly identified with Congrina Jordan & Hubbs, 1925, and specifically with C. guttulata. Leptocephalus trilineatus Castle, 1964 and L. geminus Castle, 1964, with similar pigmentation from the southwest Pacific, must therefore also belong to Congrina. Ten eels from southern Mozambique (Galathea Expedition and a commercial trawler) are identified with Coloconger scholesi Chan, 1967, otherwise known only from the South China Sea. A metamorphic lepto-cephalus of C. raniceps Alcock, 1889, from off southern India (Galathea) shows remnants of larval pigmentation, and permits the recognition for the first time of the larval characters of Coloconger.

  • Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 7 , A survey of ichthyological literature from 1758 until the end of 1968 reveals that information on eel larvae (leptocephali) is widely scattered and contained in at least 600 different papers. A synthesis of tlris information, essential for the correlation of larval eels with their adult species, is attempted here as a necessary adjunct to the further development of systematic studies on adults. About 450 forms of eel larvae have been described, of which nearly 100 have been at least tentatively identified; some 200 have been named as species of die genus Leptocephahis Grono- vius, 1763 (now a rejected name in Zoology), or of other larval genera; the remainder have not been named. Systematic and bibliographic information on these cel larvae is presented together with a geographic checklist and a list of myomere numbers in leptocephali. Reports of eel eggs and prelarvae are not included but these may be found in some of the papers listed. The leptocephalous larvae of other groups of fishes are excluded from this index, although references are made to relevant sources of information.

  • Description: Here the agreement between these two Ministers comes to an abrupt end. For while Dr. Koornhof says categorically that the only honourable way in which to do this, is by developing the resources of the homelands, Mr. Froneman states equally categorically that it is no part of the white man's duty to do so. Dr. Koornhof speaks of the moral and altruistic elements in the policy of separate development. Mr. Froneman speaks in the harshest and most callous terms of millions of "surplus" Africans, who must be sent back to their homelands, no matter what awaits them there. He says that African labourers in "white" areas must not be burdened with "superfluous appendages", such as wives, children, and dependents who could not provide service. These two men are in the same Cabinet. If one has been rebuked, it was done in private. And if it was done, it was no doubt done in a semi-jocular manner — "Fronnie, old boy, we all know what you mean, but you must learn to talk prettily." These two men do not represent two irreconcilable wings of the Nationalist Party, they represent the two essential elements of the policy of separate development. And these two elements are essential to each other. Either by itself would be dangerous. Either by itself would be unacceptable. Neither Mr. Froneman nor Dr. Koornhof has reached the stage when one cannot bear to be in the same Cabinet as the other. Although each of these two elements and each of these prototypes, is essential to the other, they do not co-exist in perfect harmony. The one is a naked baas, the other is a bass clothed in soft raiment. The first thinks the second is a sissy, the second thinks the first is a barbarian. They do not say so publicly, but their newspapers do, and that is not good. In the absence of any official pronouncement we must assume that they have been told that the sissy and the barbarian are essential to one another. The sissy will get the barbarian into nice company, the barbarian will protect the sissy if the nice company turns nasty. Why is it that although the barbarian and the sissy do not co-exist in harmony, they are (in spite of the dreams of rift-seekers) essential, the one to the other? Why do the callousness and the altruism not go to civil war? The answer is that neither of them is a fundamental. They are both imposed on something that is fundamental, and that is the preservation of white supremacy (which can be more gently called self-preservation, a soft word that turns wrath in some circles). Neither the callousness nor the altruism is part of the deep monolithic core. The cracks can show, the paint can peel, the fragments can flake off, but the core remains untouched. In times of ease (such as the present), one sees and hears and reads much of the cracking and the fragmentation. In times of danger (which will come), one is conscious of the monolithic core, which is like an ironwood heart in a softwood tree. If we accept the view that Mr. Froneman and Dr. Koornhof have something deep and fundamental in common, is there therefore nothing to choose between them? Or are Dr. Koornhof and his kind, bearers of hope for the future? For Mr. Froneman and his kind certainly are not. Their dream of the total separation of the races, if one chooses to dignfiy it by the use of such a term, is a dream which must be realised at whatever cost, and the cost will be the bitterness, and inevitably the hatred, of millions of Africans towards the white masters who make such heartless use of their power. It is claimed by our rulers that such bitterness does not exist except in the imaginations of sentimentalists and agitators, and it is true that the patience of Africans appears to be infinite. It takes a train disaster to strip the mask from the smiling face. Are Dr. Koornhof and his kind, bearers of hope for the future? Like Mr. Froneman, Dr. Koornhof believes in the policy of separate development. He does not attempt to conceal that this is to be done in the interests of self- preservation. If the homelands are developed, then more and more Africans will leave "white" South Africa to return to the places from which they were driven by the need for work, money, and food. Although Dr. Koornhof did not say so, it is justifiable to infer that he believes that white South Africa will be more secure if it sheds itself of its Africans, surplus or otherwise. There will be no competition in the labour market, no crime by rootless young black men in the beautiful white suburbs, and most important of all, no night of the long knife. But Dr. Koornhof wants this transformation to be made with justice. There must be work and food and hope in the homelands, and they must be helped to achieve autonomy, political and cultural and economic. It is the economic autonomy that poses the greatest difficulty. Even if it does not mean economic independence, it should mean a healthy economic relationship with "white" South Africa. This is where Mr. Froneman parts company with Dr. Koornhof. And this is where REALITY parts company with Dr. Koornhof too. The recognition that there can he no political and cultural autonomy unless there is at least a healthy relationship with “white” South Africa, is for REALITY a recognition by its political opponents that there are moral considera' tions which transcend those of naed self-preservation. These considerations were blue-printed (inadequately) by Professor Tomlinson in the ninteen- fifties, inexplicably ignored by Dr, Verwoerd (his biographer may one day explain why), and are now, in 1969, alternately honoured and dismissed by a two-tongued Cabinet. In any case REALITY rejects the Tomlinson or any other similar blueprint. The wealth of “white” South Africa was created by all of us jointly, and it belongs to all those who created is. , Journal includes vol. 1 no. 2 to vol. 1 no. 6 ; vol 2 no. 1 to vol. 2 no. 6 and vol. 3 no. 1 to vol. 3 no. 6 , Vol. 2 no. 3 is missing
