Lenath of the head three and four-fifths to four, of caudal fin 

 five and three-fifths to five and four-fifths, of pectoral fin three and 

 a half, height of body beneath the origin of the second dorsal five 

 and a fourth in the total length. The eye is situated in the 

 upper half of the head and just touches the dorsal pi'ofile, its 

 diameter is two-sevenths of the length of the head, and about five- 

 sixths of that of the snout, which is oblique and slightly concave, 

 whereas the occiput is fiat. The interorbital space is also slightly 

 concave, and is three- sevenths of the diameter of the eye. The 

 clett of the mouth is almost horizontal, the upper jaw being the 

 longer, and the maxilla extending to the front margin of the eye. 

 A short simple fleshy tentacle above the middle of the eye. Villi- 

 form teeth on the jaws, vomer, and palate, with an enlarged row 

 in front on the jaws. The first dorsal fin commences above the 

 middle of the opercle, and is subequal in height to the two others; 

 the second dorsal commences a little behind the base of the 

 pectoral, and is sub-continuous with the first, while the third com- 

 mences above the eighth anal i-ay, and is separated from the 



"Counting obliquely backwards from the origin of the third dorsal to the 

 base of the anal tin.
