Description. This fish is of an elongated, slightly compressed, sub-fusiform 

 shape ; it is thin along the back, and almost carinated in front of the dorsal fin, 

 thicker and rounded along the belly, though thickest just below the lateral line. 

 The head is large, long, and very broad between the eyes, with orbits rather pro- 

 jecting ; the snout is narrow, though rounded. The eye is large, rather longest 

 horizontally, with its posterior border nearer the snout than the angle of the oper- 

 cle, and with its inferior margin above the median plane of the head ; the pupil 

 is nearly circular, and deep blue, with a golden iris, covered behind with a nictitat- 

 ing membrane. The nostrils are midway between the eye and the snout ; they are 

 elliptical in form, closely approximated, and nearly of the same size ; the anterior 

 is rather the lower, though both are above the median plane of the eye, and on a 

 line within the margin of the orbit.
