Length of head 1/7, of caudal 2/11, height of body 2/11 of the total 
length. Eyes, high up, diameter 2/9 of length of head, 2 diameters from 
end of snout, | a diameter apart. Snout somewhat swollen, barbels about 
equal in length to the diameter of the eye. Fins ; dorsal arises midway 
between the posterior margin of the orbit and the base ol the caudal. Uic 
anal in the last third of the body. Caudal cut square. Scales, distinct. 
Lateral line, absent. Colours, straw coloured with a badly developed dark 
line along the centre of the body, and irregular greyish pencilling* along 
the back. Pectoral, ventral, and anal yellowish ; dorsal with several irre- 
gular and badly marked black bands. Caudal with a dark mark at its base, 
and several irregularly directed vertical bands. 
Hah . — Upper Assam. The specimen from which this description is drawn 
up was taken at the Bezwada anicut on the Kistna, and it agrees moderate- 
ly well with McClelland’s figure and definition.

Length of head more than height of body. Lyes, situated be oie e 
middle of the length of the head, and 2 diameters from end of snout. 
Snout rather depressed, no ridge between the orbits. Barbels ; four rostral, 
as long as the diameter of the orbit, and two shorter maxillary ones. 
Fins; dorsal commences midway between the anterior margm of the orbit 
and the base of the anal, and slightly hi advance of the ventral. . The 
pectoral does not reach the ventral, nor the latter the anal. Scales, minute. 
The two specimens from which this description was drawn up were labelled 
as above in the Calcutta Museum, but their colours were bleached, whilst 
their tails were destroyed. The caudal fin should be rounded and entire. 
McClelland’s description gives an apparently different fish ; he says that 
the head is raised obliquely as in the Ferilamps, but this is a frequent 
post-mortem appearance ; the ridge between the eyes being sharp and bony. 
Colours, above clouded with brown, silvery beneath, with a dark nebulous 
streak along the side. Several small bars across the caudal fin.
