the ventral ; the latter is very small, a little above half as long as 

 the pectoral, and does not reach the anal. Caudal deeply lobed, 

 with its upper lobe rather produced. Colour on the upper surface 

 dull leaden, sides and abdomen whitish, adipose dorsal with a black 

 blotch ; pectoral, ventral, and outer half of anal dark.

 Length of head 3| to 4, of caudal fin 6 to 7, height of body 5 in 

 the total length. Eyes diameter 5 to 6 in length of head, 2-J to 3 

 diameters from the end of snout, and 2 to 2 apart. The greatest 

 width of the head rather exceeds its height and equals four sevenths 

 of its length. Snout elongated and a little depressed, the upper 



i'aw the longer, the width of the gape equals two sevenths of the 

 ength of the head, cleft short, extending one third of the distance 

 to the orbit ; median longitudinal groove on the head shallow, an- 

 teriorly becoming narrow, and posteriorly deep, extending nearly 

 to the base of the occipital process. Upper surface of the head 

 behind the middle of the orbit granulated, as is also the occipital 

 process, which is rather wider at its base than it is long, has nearly 

 straight lateral edges, and reaches the narrow basal bone of the 

 dorsal fin. Barbels short, the maxillary pair do not quite reach 

 the eye, the outer raandibular are still shorter, and the internal the 

 shortest. Teeth those on the palate villiform, in two small 

 patches wide asunder, one on either side of the palate, not longer 

 than the diameter of the eye. Fins dorsal one fourth higher 

 than the body, its spine not very strong, rather above half as long 

 as the head, rugose anteriorly, serrated posteriorly ; length of the 

 base of the adipose dorsal equal to two thirds of that of the rayed 

 fin. Pectoral scarcely reaching the ventral ; pectoral spine as long 

 as that of the dorsal, or a little longer, serrated internally. 

 Ventral reaching the anal ; caudal forked. Colour silvery leaden 

 along the back when fresh, a series of about fifteen minutely spotted 

 vertical bands seen on the body. Fins stained with grey.
