Type. Imperfect head and trunk, wanting fins ; British Museum. 



A large species, attaining a length of not less than 0'35. 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- 

 what less than one quarter of the total length ; external bones 

 marked with coarse vermiculating rugae. Pelvic fins nearly as 

 large as the pectorals, arising midway between the latter and the 

 anal ; dorsal arising about the middle of the back, immediately 

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

 almost completely in advance of the anal, which equals it in size 

 and form. Scales large, those of the middle of the flank slightly 

 deeper than broad ; dorso-lateral scales smooth, with non-serrated 

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