_ The broad, dejjressed, projecting, marginally inflated snout 



is one third of the head 



in length and twice the 



major diameter of the 



oval eye ; at least half 



its extent is preoral. 



The mouth is a small, 



quite inferior, crescen- 



tic orifice, in width 



equal to the diameter 



of the eye, its angle 



barely reaching tlie 



vertical through the 

 anterior border of the 

 orbit, though the max- 

 illa reaches nearly to 

 the vertical through 

 the middle of the orbit; 

 it is strongly protrac- X

 to be a narrow band of I, 

 very minute teeth in | 

 the inner aspect of the ^ 

 upper jaw ; but tiie .^im

 narrow, the mem-

 the isthmus anteriorly ; 

 gill-rakers short, 

 coarse, cartilaginous.
