hindborder of eye or somewhat farther. The length of head 

 is equal to its distance from dorsal and equal to or shorter 

 than the distance between dorsal and anal. Pectorals have 16 18 

 (after BLEEKER 22 24) rays and go 2'/ 2 3 times in the length 

 of head. Snout broader at its base than its length. Tail longer 

 than head and trunk. Intermaxillary and vomerine teeth forming 

 a rhombic band with slightly concave sideborders; posteriorly 

 rapidly tapering into a point, which does not reach so far as 

 the maxillary teeth. The maxillary teeth arranged in two outer 

 series, the inner one of which carries the longest teeth, which 

 border an edentulous longitudinal groove. Inward of this groove 

 there are about 3 series of teeth opposite to the vomerine 

 band but separated from it by a groove. These 3 series are 

 posteriorly gradually reduced to one series. Mandibulary teeth 

 outside the edentulous groove anteriorly in 2 3 series, of 

 which the inner one has the largest teeth, which are continued 

 posteriorly. Inside of the groove there are anteriorly several 

 series of teeth, tapering posteriorly into one series. In alcohol- 

 specimens ventral surface light, dorsal surface dark, especially the 

 last with different large spots. Length more than 1600 mm.
