distance — how much more cannot be determined, but the fin is evidently 

 short and rounded in contour, the upper rays longest. Its base is 

 stout-peduncular, and thickly covered with scales. 



The distance of the ventrals from the snout is equal to that of the 

 dorsal, though its insertion is slightly in advance of that of the dorsal. 

 The two ventrals are closely adjacent, separated by a narrow groove, 

 broad, with peduncle-like bases, thickly covered with scales. They 

 are provided with two spines and eight or nine (as nearlj' as the speci- 

 men will permit determination) rays.
