which it would seem best to retain Lacepede's name for the Indian 

 form. Bennet records a fish from Polynesia, which may probably be 

 identical.^®

This single dried example is in poor condition. It agrees with 

 Goode's figure^^ so far as one is able to judge from its preservation.

 snout and base of caudal. Origin of spinous dorsal inserted posterior to 

 origin of pectoral a distance about equal to h length of snout. 

 Origin of the anal would fall about opposite base of last dorsal 

 ray. First two dorsal finlets small, especially the first which is like 

 that of Germo germon}^ Ridge along upper edge of pectoral distinct

 abdomen seem to be separated by oblique lines. Length 27 inches.

Goode's figure^'' is rather poor. It shows the origin of the spinous dor- 

 sal opposite that of the pectoral, and the pectoral fin reaching opposite 

 the first dorsal finlet, which is also not especially smaller than the
