524 Storer on the 
short, stout, smooth, and a little incurved. Mouth 
large, prominent, armed with large, strong teeth; 
eyes large, and distant an inch and a half from the 
mouth; nostrils, less than a quarter of an inch in 
front of the eyes. 
The fin rays are: D. 10; P. 12; A. 10; C. 10. 
The length of this specimen, in its present dried 
state, is fourteen inches. From the contracted and 
wrinkled appearance of the ligamentary portion at 
the base of the tail, it must vary considerably from 
the size of the living fish. | 
From observing the plates alone of the “ bicauda- 
lis,” this might be mistaken by a careless observer 
for that species; but a careful examination of both 
the figures and the descriptions, shows them to be 
distinct. 
The number of the fin rays of the two species do 
not vary; but the comparatively plane and immacu- 
late surface of the one, corresponds but little with the 
very elevated striæ and numerous spots which cover 
the exterior of the other.
