Length of head 4f , of caudal ^, height of body 4 in the total length. %es— 4 diameters in the length 

 of head, 1 diameter from the end of snout, and 2 apart. Interorbital space' slightly convex. The greatest 

 width of the head equals its length excluding the snout. Mouth narrow, its width equallmg 2/7 of the length 

 of the head. Snout overhanging the mouth : no lateral lobe. Lips continuous, and having a distinct inner 

 fold in their entire circumference : both lips fringed. A horny inner covering to either lip. Ba/rbeh— no 

 • rostral ones, a short pair to the maxUla. Jfes— dorsal arises anterior to the ventral, and slightly nearer to the 

 end of the snout than the base of the caudal fin, anteriorly 2/3 as high as the body, its upper edge concave. 

 Pectoral as long as the head excluding the snout, it does not reach the ventral nor the latter the anal. Anal 

 when laid flat reaches the base of the caudal which is deeply forked. Lateral-Tme—Q rows of scales between it 

 and the base of the ventral fin. CoZoiws— bluish with a yellowish tinge on the sides and beneath. Outer half 

 of anal nearly black, and a blackish lunule on the caudal. « ^ .. 



Eahitat.—B.\Ye.v at the base of the Sind Hills. A single specimen obtained, which is figured life-size.

Length of head 5^ to 6i, of caudal 6, height of body 5 to 5g in the total length. Uyes — situated 

 either in, or {in the young) rather before the middle of the length of the head, diameter 5 to 6-|- in 

 the total length of head, and 2^ to 3 diameters apart. Greatest width of the head equals its length excluding 

 the snout. Dorsal profile more convex than that of the abdomen. Mouth rather narrow, snout overhanging 

 the jaws, generally with a groove across it, and covered with pores : no lateral lobb. Lips thick and 

 continuous, but the fold across the lower jaw is interrupted. A cartilaginous layer on iaside of both lips. 

 GiU-rakers, closely set, about 1/3 as long as the eye. Barbels — a small maxillary pair. • Teeth— rphaxjngeal, 

 plough-shaped, 6, 4, 2/2, 4, 6. Fims — dorsal arises midway between the front of the snout and the end 

 of the base of the anal fin, its upper edge is slightly concave in the young, becoming deeply so in the adult. 

 Pectoral does not extend to the ventral, nor the latter to the anal. Caudal deeply forked, the upper lobe the 

 longer : its central rays being about 1/3 the length of the outer ones in the young, 2/7 in the adult. 

 Scales — 6 to 7 rows between the lateral-line and base of the ventral fin. Golowrs — grayish, darkest along the 

 back, each scale tinged with red : a darkish band along the side, or short gray bars passing to the lateral-liae. 

 Fins with a faint reddish hue. Outer edge of dorsal rather stained. 



Hamilton Buchanan I.e. observes of G. dero " at each corner of the mouth is a minute tendril," thus 

 showing the figure to be incorrect on this point. I have the young from Goalpara having the same proportions 

 as given in H. B.'s figure. The specimen in the British Museum, Catal. of Cirrhina dyochila, " a. 4|- inches long. 

 Cachar," is likewise identical. 



Sabitat. — Along the Sind hills and Himalayas, also in the Brahmaputra in Assam.

Length of head 5 to 5|-, of caudal 5|-, height of body 3f to 4|- ia the total length. Hyes — situated in the 

 commencement of the posterior 1/2 of the head in the young, still further back in the adult : diameter from 6 

 to 9 in the length of the head, and from Z\ to 5 apart. Width of head equals 2/3 of its length : its lower 

 surface being very broad and flat. Snout conical, projecting, and with a distinct lateral lobe (in General
