Length of head 5 to 5^, of caudal 5 to 5^, height of body 3^ to 4 in the total length. %es— diameter 

 3 to 3i in the length of head, 1 diameter from end of snout, and 1-| apart. Third suborbital bone nearly 

 touches the preopercular ridge. i)((;-6eZs— rostral half as long as the orbit, maxillary ones very short, in some 

 specimens the latter are entirely absent. Fins— the dorsal arises midway between the base of the caudal fin 

 and the posterior edge of the eye, its anterior half is in advance of the anal. CoZowrs— back steel-blue, some 

 irregular vertical yellow lines on the fore-part of the body, and three or four blue bands along the sides, the 

 cent'ral ones coalescing so as to form a broad bluish band along the middle of the caudal fin. 



Habitat. — Western coast of India and Ceylon ; attaining 6 inches in length.

 Length of head 5, of caudal 5 to 5^, height of body 4 to 4} in the total length. E(/es— diameter 2/7 to 

 1/4 of length of head, 1 diameter from end of snout, and l-i- apart. Third suborbital bone nearly touches the 

 preopercuiar ridge. Cleft of mouth oblique and extending to under the anterior margin of the orbit, a bluntish 

 knob at the symphysis. 'Barbels — rostral half as long as the orbit, the maxillary ones minute. Fins — the 

 dorsal arises midway between the centre of the orbit and the base of the caudal fin, extending to over the 

 anterior anal rays, it is 2/3 as high as the body. Pectoral as long as head without the snout, nearly reaching 

 the ventral, which last does not extend as far as the anal. Caudal forked but not deeply so. Lateral-line-— 

 li- rows of scales between it and the base of the ventral fin : 13 rows before the dorsal fin. Colours — yellowish 

 white, a wide bluish band extends along the body from the eye to the centre of the base of the caudal fin, in 

 its course are sometimes several round silvery spots, below it is another narrow band (which occasionally joins 

 the central one anteriorly) ; there are two other lighter bands above the central one. The intermediate ground 

 colour is yellow. Fins yellowish. Dorsal and anal fins each with a broad bluish band along their outer half. 

 In some specimens there is a dark mark behind the gill-opening. 



JT(i6('^i.f.— Himalayas at Darjeeling and the whole of the Assam district as high as Suddya, the Naga 

 and Garo hills, Tenasserim and the Deccan.

Length of head 5, of caudal 5, height of body 3^- to 4 in the total length. Eyes— diameter 1/3 of length 

 of head, 3/4 of a diameter from end of snout. Lower jaw the longer, with a knob at the symphysis. Mouth 

 oblique. Barbels— rostral a little shorter than the head ; maxillary pair slightly longer. Fins— the posterior 

 dorsal rays are above the anterior ones of the anal. Caudal slightly emarginate. ,SVa?es— 2^ rows between 

 the lateral-line and base of the ventral fin : 18 rows before the dorsal fin. Colours— hack olive colour, abdomen 

 silvery, sides with several narrow blue lines, which in the anterior half or two-thirds of the body, form a 

 beautiful network ; a dark spot behind gill covers. Anal fin with two or three blue stripes. A specimen from 

 Darjeeling was deficient in ventral fins. 



Habitat.— BengaX, Behar, Himalayas at Darjeeling, also the hills above Akyab ; grows to 5 or 6 inches m 

 length.
