Colour blackish, with numerous small silvery spots : two longi- 

 tudinal rows of about 8 each on the belly; a row more widely 

 separated halfway between the median line of the belly and the 

 lateral line ; a few just below the lateral line and a close row of 

 about 20 at each side of the anal fin up to the base of the caudal. 



Head large ; compared with length of fish without caudal as 1 to 

 yf. Profile quadratic : snout very short, about half the diameter of 

 the eye, which is round and large, being nearly 11 mm. in diameter or 

 about one third the length of the head. It is surrounded by a thin 

 bony crest, which is more prominent above. The space between the 

 eyes is concave, and at the fore part of it there is a thin bony crest 

 along the snout. The inside of the mouth and gill-covers is black. 

 The rictus reaches to about the vertical of the posterior part of the 

 orbit. The upper border of the mouth is formed entirely of the 

 premaxillaries. Both premaxillary and maxiUary are dilated pos- 

 teriorly. 



Minute teeth in narrow brush-like bands are found in both jaws 

 and on the palatines ; the innermost teeth are rather larger. There 

 are also teeth on the vomer, and the cntopterygoids are roughened 

 with asperities. 



The tonr/ueis of peculiar form, being boat-shaped, hollowed at the 

 middle, with a small tip. The gill-covers are scaly ; the fore edge 

 of the preopercle is turned up so as to form a thin vertical crest, 

 which is continued nearly up to the angle of the mouth. The inner 

 edges of the mandibular pieces are also turned up iiito crests. 



The fii'st dorsal fin commences over the root of the pectorals and 

 much in advance of the root of the ventrals ; its base is only 1 6 mm. 

 long ; it does not extend quite so far as the end of the anal. As
