above and arched below; its length is contained from 4 to 4.5 times in the length of the body 

 excluding the caudal. It is slightly higher than broad. The snout is thick and prominent 

 with broadly rounded anterior edge; its length is contained about 3.5 times in the length 

 of the head. The interorbital space is flat and wide, with a prominent muchal region; it 

 is nearly twice as broad as the orbital width. The eyes are moderate and their diameter is 

 contained from 5.4 to 5.7 times in the length of the head and about 1.5 times in the length 

 of the snout.

 Manasbal Lake, showing contour of head, nature of mouth, jaws, Hps and barbels. Nat. size. The dotted portion 

 of the lower jaw indicates the position of the cartilaginous layer on its inner margin.

The origin of the dorsal fin is opposite that of the ventrals and is much nearer the 

 root of the caudal than the tip of the snout. The dorsal spine is long and strong and has 

 from 18 to 21 coarse serrations posteriorly (Te.xt-figure 8) ; it is slightly shorter than the 

 head f)r equal to the length of the head behind the nostrils which are situated much nearer 

 the anterior margin of the eye than the tip of the snout. The anal fin is somewhat narrow 

 and its longest ray is almost as long as that of the dorsal; in the grown-up specimens it 

 almost reaches the root of the caudal (Text-figure 9), while in young and half-grown indi- 

 viduals it is separated by a little distance. The pectorals are much shorter than the head, 

 alxjut as long as the head l)ehind the anterior margin of the eyes; they are separated from 

 the ventrals by a wide space. The ventrals are a little shorter than the pectorals and are 

 separated from the insertion of the anal by a considerable distance. The caudal is deeply
