The uppermost pectoral ray is the strongest, longer than

The height of the body is two ninths of the total length 

 (without caudal) ; the length of the head is contained thrice 

 and two thirds in it ; the depth of the head equals its length 

 without snout. The diameter of the eye is somewhat more 

 than one third of the length of the head ; distance between 

 the posterior margin of the orbit and the prseopercular edge 

 one third of the diameter of the eye. Snout short, obtuse, 

 with its upper profile descending in a strong curve, and with 

 the jaws nearly equal anteriorly. The maxillary reaches to
