Type. Imperfect head and trunk, wanting fins ; British Museum. 
A large species, attaining a length of not less than 0 55. Trunk 
regularly fusiform, the dorsal margin arched in advance of the 
dorsal fin, and the maximum depth contained about four times in 
the total length. Head with opercular apparatus occupying some¬

behind the pelvic fins, relatively small, short-based, and triangular,

posterior margins; ventro-lateral scales with few posterior serra-
