at the angle of the mouth, thicker and slightly longer than the other 

 two pairs. The lips do not cover the jaws. Snout soft ; nostrils at 

 anterior superior angle of the orhit, the posterior oval, the anterior 

 circular, the two divided from one another by a valve. Summit of 

 head smooth. Branchial aperture small, vertical. Isthmus wide. 

 Branchiostegal membranes concealed. 



Fins. Dorsal situated midway between end of snout and the base 

 of the caudal fin, as well as opposite the ventral. Pectoral arises 

 nearly under opercles, and extends to the base of the ventral. The 

 anal is situated in the posterior fifth of the body. Dorsal fin highest 

 anteriorly. Pectoral subhorizontal, with a broad fleshy base, its an- 

 terior margin rounded." Ventral also subhorizontal, and its front 

 margin rounded. Caudal lobed in its posterior third, and the infe- 

 rior rays produced. 



Scales small, none above, or on the head, or anterior surface of 

 the abdomen ; a {qw before the anus (except in the mesial line), 

 which is situated opposite the posterior extremity of the ventral fin. 

 They are roughened in circular or horizontal furrows ; edges smooth. 



Teeth. Pharyngeal teeth 5/5. 



Lateral line straight from behind the orbit to the centre of the 

 caudal fin. It consists of single tubes in each scale. 



Colours. DuU olive, becoming yellow beneath, with deep-brown 

 blotches. Fins diaphanous ; dorsal with three rows of dark spots ; 

 ventral with three or four ; anal with two ; pectoral yellowish, dark 

 anteriorly, and with three rows of dots across it ; caudal with three 

 irregular bands and black tips. 



Out of eight specimens the largest was 3| inches long. 



Hub. Wynaad, in streams. 



Garra alta, sp. nov. 



Cul korava (Tarn.). Stone Ophiocephalus.

Length of head |^, of pectoral above \, of base of dorsal \, of anal 

 Jg^, of caudal i of the total length. Height of head ^, of body ^, of 

 dorsal i, of anal \ of the total length. 



Eye circular, situated near to the upper profile of the head, and 

 directed slightly outwards and upwards. Diameter ^ of length of 

 head, 2^ diameters apart, 3|- diameters from end of snout. 



The abdominal ])rofile in this species is nearly horizontal, from the 

 anterior extremity of the snout to the base of the caudal fin ; whilst 

 the dorsal profile is much elevated, forming a curve, from the ante- 

 rior margin of the snout to the base of the dorsal fin. The head at 

 the occiput is broad, whilst the snout is also comparatively wide. 



Snout with a badly developed transverse cleft, and the whole 

 covered with very large glands. Mouth transverse and below, its 

 gape equal to two-thirds the length of the base of the dorsal fin. An 

 oval suctorial disk situated behind the lower jaw. One }iair of cirri 

 on snout, equal in length to the diameter of the orbit ; the maxillary 

 pair only one-third of that length.
