Length of head from 5 to 6, of caudal 3| to 3f , height of body from 4 to 4^ in 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 jaw the longer. Barbels — four, all very short. Fins — dorsal rather higher than the body, and 

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

 longer 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 the ventral fin : 16 rows before the base of 

 the dorsal fin. OoZows— silvery, caudal and dorsal edged with black. 



Habitat. — Cottayam in Travancore, from whence I received specimens up to 4i inches in length, collected 

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

 , Length of head 4f , of caudal 4|, height of body 3i- in the total length. Eyes — 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. Upper jaw somewhat the longer. 

 Ba/rbels — two 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 the 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 arises 

 beneath the fourth dorsal ray and reaches the commencement of the anal. Caadal deeply forked. Lateral-line — 

 strongly marked in its first few scales, the rows of scales nearly regular : 8 rows between the lateral-line and 

 base of ventral fin. Free portion of the tail as long as high. Golowrs — silvery, opercles golden. 



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



* A difficulty exists respecting the localities given fcr the following specimens in the British Museum collection -.—Osteolrama 

 ra/paa, Gunther, or RoUee Vigorsvi, Sykes, is stated to have been presented by Lieut.-Col. Playfair from the "northern parts of the 

 Indian Peninsula." Referring to Preface, p. iv and to Laheo striolatus, Gunther, p. 62==L. boggut, Sykes, one is led to conclude that 

 by this term is meant Poona in the Deccan. The same expression for Poona is seen under the head of Osteolrama or Rohtee Ogilbii,
