 from chest and as far as the posterior margin of the base of the ventrals. Colours — dark brown with darker 

 blotches : caudal banded.

Length of head 5f to 6, of caudal 6, height of body 7 in the total length. Eijfs — directed upwards 

 and outwards, diameter 1/.5 of length of head, 3 diameters from end of snout, 2 diameters apart. Interorbital 

 space convex. Snout broad, depressed : lips fringed. Rostral barbels short, their length equalling about 2/3 

 of the diameter of the orbit, the pair at the angle of the mouth thicker and slightly longer. Teeth — pharyngeal, 

 o, in one row. Fins — dorsal arising rather nearer the end of snout than the base of caudal. Pectoral 

 nearly reaching the ventral, its outer 8 rays unbranched Two outer ventral rays simple. Caudal lobed in its 

 posterior third. Scales — cycloid. Lateral-line — complete. Colours — dull olive, becoming yellowish beneath. 

 Large brown blotches on the body. Dorsal fin with three rows of dull spots : pectoral and venti'al with three 

 or four, anal with two, caudal with three irregular bands, and black tips. 



Habitat. — Wynaad, the Bowany river, also the Himalayas. The specimen figured (from the Wynaad) 

 is a male.

Length of head 1/5, of caudal 1/5, height of body neai'ly 1/5 of the total length. Eyes — small, behind 

 the middle of the length of the head, about 4 diameters from end of snout, and 3 diameters apart. Snout pointed. 

 Upper lip fimbriated. Barbels — short, six in number, the maxillary pair the longest. Fi7is — dorsal arises 

 slightly in advance of the ventrals, and midway between the snout and the base of the-caudal fin, its upper 

 margin straight. Pectoral, having its five outer rays unbranched, reaches two-thirds of the distance to the ventral, 

 and the latter above half-way to the anal. Caudal deeply emarginate, its lobes pointed. Scales — smooth, with a 

 raised keel along their centres, and inci'casing in size in the last half of the body. Lateral-line — complete. 

 Air-vessel — absent. Colours — brownish, with a wide dark chestnut band passing from the snout through the 

 orbit to the base of the dorsal fin, which last has a black centre. Caudal deep brown with white margins. - A 

 black bar across the base of the ventrals. 



This species appears closely allied to Buchanan's fish from the rivers of Northern Bengal, which however 

 is said to have tlie snout much longer than the remainder of the head. The ej-es are represented as large, but 

 only stated to be far back and globular. Fins — dorsal high, anteriorly with a very oblique upper margin. 

 Colours — superiorly greenish, with scattered dots: sides clouded : abdomen whitish. Fins dotted. 



Habitat. — Three specimens are in the Calcutta Museum, from the Tenasserim provinces.
