D. 10. A. 70. V. 8. P. 12. L. lat. 47. L. transv. f . 



The depth of the body is cue fourth of the total length (without 

 caudal), the length of the head one sixth. Mandible strongly pro- 

 jecting beyond the mouth ; maxillary not reaching below the anterior 

 border of the eye ; praemaxillary teeth 1 5, maxillary (on each side) 

 11, mandibular 14; mandibular teeth largest, maxillary smallest. 

 The diameter of the eye equals nearly two fifths the length of the 

 head, and exceeds the width of the interorbital space. The pectoral 

 fins reach nearly the extremity of the veutrals, which are small ; 

 the dorsal originates above the 23rd anal ray. Colourless ; sides of 

 head and a lateral band above the lateral line silvery. 



Total length 9.5 miliim.

Snout produced into a long narrow tube, which is bent down- 

 wards ; the diameter of this tube, halfway between its extremity 

 and the eye, is one eighth of the length of the snout. The 

 distance between the eye and the base of the pectoral equals 

 two thirds the length of the snout. Mouth very narrow, its cleft 

 not twice as long as the diameter of the eye. Vent below the eye. 

 Anal commencing nearer the eye than the gill-opening; 185-188 

 rays. The greatest depth of the body is contained once and three 

 fifths in the length of the head, and five times in the total. Scales 

 on the upper and lower parts very small, those in the middle of the 

 side of moderate size. Uniform brown. 



Total length 125 miliim.
