Leno-th of head from 5 to G, of caudal 3^ to 3f , height of body from 4 to 4^ iu the total length. Eyes — 

 longest transversely, diameter 2/5 of length of head, 2/3 of a diameter from end of snout, and 1 apart. Profile 

 over nape rather concave, a considerable rise to the base of the dorsal fin. Mouth small, horseshoe-shaped, 

 upper iaw the longer. Barbels— iouv, all very short. F(/(.s— dorsal rather higlier than the body, and 

 commencino- midway between the end of the snout and the base of the caudal, its spine weak, as long or rather 

 lono-er than" the head, and serrated posteriorly in almost its whole extent. Caudal deeply forked, lobes of equal 

 length. Scales— 5^ rows between the lateral-line and the base of tlie ventral fin : 15 rows before the base ot 

 the dorsal fin. Cofo«rs — silvery, caudal and dorsal edged with black. 



Habitat.— CottvLj&ra in travancore, from whence I received specimens up to 4^ inches in length, collected 

 by the Rev. H. Baker, after whom I named the species.

Length of head 4f , of caudal 4f , height of body U in the total length, j^^/yes— diameter 2| in the length 

 of the head"^ 2/3 of a diameter from end of snout, and also apart. Interorbital space very concave. Profile over 

 nape concave, from thence a considerable rise to the base of the dorsal fin. Upjier jaw somewhat the longer. 

 Barbels— tvfo pairs, all about as long as the eye. Fins — dorsal commences midway between the front edge of 

 the eye and the base of the caudal fin, it is 3/4 as high as tlio body, its last undivided ray osseous, very strong, 

 serrated, and as long as the head excluding the snout. Pectoral nearly as long as the head. Ventral a,rises 

 beneath the fourth dorsal ray and reaches the commencement of the anal. Caudal deeply forked. Lateral-} i ue— 

 strongly marked in its first few scales, the rows of scales nearly regular : « rows between tlie lateral-line and 

 base of ventral fin. Free portion of the tail as long as high. C'o?o!()-s— silvery, opercles golden. 

 Habitat. — Bowany river at base of the Neilgherry hills. 



* A (iifficiilty exists respecting the localities giv( n f< r the following specimens in the British Museum collection -.-Osteohrama
