Bleeker has published a Revision of Indo-pelagic species of Urano- 
scopus, giving descriptions of U. cognatus. Cantor, p. 49, bicinctus, Schleg., 
p. 61, asper, Schleg., p. 63, and oligolepis, Blkr., p. 55. The latter species

greatly resembles. In order to facilitate the distinction of these three 
species, a detailed diag:^osis of U. scaber, L., is appended in a note, in 
which is also described U. capensis, sp. n., p. 58, Cape of Good Hope.
