The type is a nearly complete fish contained in the Paris Museum of Natural 
History. 
The specimens representing this species attain on the average a length of about 
30 cm. Maximum depth of trunk equalling half the length of the fish exclusive 
of the caudal fin; head with opercular apparatus occupying about one-quarter of 
the total length. Teeth of the splenial bone smooth, the outermost indented; the 
inner or principal series equalling in breadth the two flanking series, of which the 
inner comprises teeth broader than long, the outer being composed of nearly round 
teeth. Dorsal fin occupying somewhat less than three-quarters of the total length 
of the back, arising almost at the highest point. 
Of this rare species a single example is preserved in the British Museum; 
several, in addition to the type, are found in the Paris Museum of Natural History, 
and one tolerably complete example is preserved in the Carnegie Museum (Cat. 
No. 4479, 4479a).
