The height of the body is contained from four times and a third to 

 four times and two-thirds in the total length (without caudal), the 

 length of the head thrice and two-thirds ; head broader than high, 

 its greatest width being three-quarters of its length ; snout depressed, 

 broad, one-third of the length of the head ; the upper jaw is some- 

 what the longer. The vomerine teeth form a narrow, continuous, 

 crescentic band. Nasal barbels much shorter than the head ; the 

 maxiUary barbels extend to the anal fin ; the outer of the mandible 

 are longer than the inner and than the head. There is a cutaneous 

 interspace between the base of the dorsal fin and the occipital process. 

 Dorsal spine rather strong, strongly serrated behind, more than half 

 as long as the head, but shorter than the first soft ray. Base of the 

 adipose fin rather shorter than that of the dorsal, its length being 

 rather less than one-half of the distance between both fins. Caudal 

 fin deeply forked, the lower lobe being rather the shorter and rounded. 

 Pectoral spine strongly serrated interiorly, as long as the head without 

 snout, extending beyond the vertical from the origin of the dorsal. 

 Yentral inserted behind the dorsal.

The length of the head is Contained thrice and a quarter or thrice 

 and a half in the total (without caudal) ; head broader than high, its 

 greatest width being equal to its length without snout ; snout spa- 

 tulate, its length being one-third, or rather less than one-third, of 

 that of the head ; the upper jaw is the longer. The band of vomerine 

 teeth is as broad as, or broader than, that of the intermaxiUaiy. 

 Maxillary barbels very long. No rugose shield between occiput and 

 dorsal fin. Dorsal spine of moderate strength, as long as the distance 

 of the eye from the end of the operculum, finely serrated behind. 

 The adipose fin is considerably shorter than the dorsal ; the length of
