Total length : 5f inch. 



The general form is elongated, compressed ; the abdomen is slightly 

 more arched than the back. The length of the head is \ of the 

 total ; the eye is placed a little nearer the muzzle than the gill-open- 

 ing ; the horizontal diameter is a little less than \ of the head, but 

 equals the distance across the forehead. The muzzle is bluntly pointed, 

 the lower jaw very little longer than the upper. The small tongue is 

 elongated oval ; in the middle a little behind the apex appears a single 

 series of very minute pointed teeth ; on the palatals they are numerous 

 but distant ; the four to six on each side of the symphysis of the lower 

 jaw are less minute ; all are deciduous. The vertical diameter at occi- 

 put is f of the length of the head ; the greatest vertical diameter of 

 the body, in front of the dorsal, is } of the total length. The dorsal 

 is placed at equal distance from the muzzle and the root of the caudal ; 

 the extent of the base is 2-j- in the length of the head ; the upper mar- 



* In the species here described a single series of 4 to 6 minute deciduous teeth-
