BOTHROL^MUS PAMPANUS. 81 



Remarks. This genus is closely allied to Lichia and to Trachinotus, but it 

 may be known from either by the absence of teeth.

Description. The head is elevated and slightly carinated above, though broad 

 between the eyes ; the facial outline descends in a regular curve to the level of the 

 nostrils, when it is suddenly incurved to the inter-maxillary bone, which gives a 

 truncated appearance to the snout. The eye is very large, and about the median 

 plane of the head ; it is one diameter of the orbit from the snout, and two diam- 

 eters from the posterior margin of the bony opercle. The nostrils are large, 

 closely approximated, nearly of the same size, and about midway between the orbit 

 and snout ; the posterior is rather the larger, and is semilunar in form ; the ante- 

 rior is semi-oval, and both are above the median plane of the eye, and on a line 

 within the orbit.
