Smith Institute of Ichthyology; No. 55 , Ucla xenogrammus, a monotypic genus of tripterygiid fishes, which is widespread in the Indo-West Pacific Ocean, is formally described, the unpublished names given by Richard Rosenblatt in 1959 being retained.

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 54 , After examination of Col. Tickell’s unpublished manuscript and colour paintings of Burmese fishes, Day (1888) listed the surgeonfish Acanthurus tristis Tickell as a synonym of A. tennentii Gunther (1861); he gave the dorsal-fin spine count of 8 and provided a colour description, including mention of a white margin on the caudal fin. Of the species of Acanthurus, only A. pyroferus Kittlitz from the Pacific has 8 dorsal spines. Randall (1956a) treated tristis as a synonym of this pecies; the differences in colouration between tristis and pyroferus were regarded as within the range of variability of the latter. Both forms were observed together in Bali in 1982-1991. A. tristis is therefore regarded as a valid species and is redescribed. In the interest of stability of nomenclature, a neotype for A. tristis is designated.
