82 SILURIDJE. 



fourth of the total (without caudal) ; head as hroad as high, its 

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

 pressed, broad, one-third, or rather less than one-third, of the length 

 of the head ; the upper jaw is somewhat the longer. The vomerine 

 teeth form a very narrow crescentic band, subinterrupted in the 

 middle. Nasal barbels half as long as the head ; the maxillary bar- 

 bels extend to, or beyond, the origin of the anal fin ; the outer barbels 

 of the lower jaw are longer than the inner, and extend nearly to the 

 extremity of the pectoral. A triangular bone in front of the dorsal 

 fin is joined by a long, bony, occipital process. Dorsal spine rather 

 feeble, half as long as the head, with both edges serrated at its ex- 

 tremity. The length of the adipose fin equals that of the dorsal, 

 and the distance between both fins. Caudal fin deeply forked, with 

 the upper lobe longest. Pectoral spine strongly serrated interiorly, 

 longer and stronger than that of the dorsal fin, extending beyond the 

 vertical from the origin of the dorsal. Ventral inserted behind the 

 dorsal. Greenish olive, with three brown longitudinal bands, the 

 middle of which commences from a large blackish ocellus behind the 

 head ; the bands and ocellus are more distinct in young specimens 

 than in old ones. Sometimes a dark spot on the middle of the root 

 of the caudal.

The height of the body is contained four times or four times and 

 a quarter in the total length (without caudal),, the length of the head 

 four times or four times and a half ; head as broad as high, granu- 

 lated above ; the occipital process is narrow and extends on to the 

 basal bone of the dorsal spine. Teeth on the palate in a crescent- 

 shaped band. Barbels long : the nasal barbels extend to the pectoral 

 fin, the maxillary barbels to the caudal. Dorsal fin pointed, higher 

 than the body ; its spine is of moderate strength, two-thirds of the
