ing a darker brown posteriorly. Fins and entire body covered with 

 round white spots, which are very fine, the size of a pin-head on 

 snout and very close together, but gradually becoming larger and far- 

 ther apart posteriorly so that over the tail they are as large as the 

 eye and the interspace between them is usually twice the width of 

 the spot. The gill-opening is black, no black at angle of jaws. 



Total length 775 m.; length to anal pore 375 m. ; length of tail 

 400 m.; head 85 m.

 more than one third the total length; head 13.8 in length; 8 in trunk. 



Mouth of moderate size, closing fully; length from tip of snout to
