Length of head 4|, of caudal fin 5|, height of body 5| in the 

 total length. Eyes very high up ; diameter 6 in length of head, 

 1 diam. from end of snout, and 1| apart. Greatest width of head 

 equals length excluding snout, its height equals half its length. 

 Upper surface of head flat. Cleft of mouth horizontal, the 1 jaws of 

 about the same length ; the maxilla reaches two diameters of the 

 orbit behind its posterior edge. Fine tentacles near the nostrils, 

 and rows of warty glands along the scaleless head. Teeth a little 

 enlarged ; no canines. Fins first dorsal low, about half as high 

 as body ; the second higher ; ventral reaches halfway to anal ; 

 caudal rounded. Anal papilla rather large. Scales those on body 

 finely ctenoid, the rows very irregular, they extend forward to half- 

 way between first dorsal and hind edge of eye. Colour olive ; 

 fins very dark grey, second dorsal spotted ; a black blotch at base
