dom exceeds six inches in length, it is an intermediate form between 

 Schizothorax and Oreinus ; it is allied to the former by the length 

 of its intestines and its habits, as it is said by Mr. Griffith to take 

 bait and worms most greedily. We are indebted to Mr. Griffith 

 also for an excellent drawing of this species. 



Intestines four lengths of the body, during the first \\ length 

 they are of considerable diameter, thence they are much contracted. 

 (Griffith.) 



Habitat. Khybur Pass, where they are very common. The head of 

 the Ali Musjid stream swarms with them; Cabul river, Himalya, 

 and Gundamuck. (Griffith.) 



There appears to be two varieties of this species, one with a some- 

 what stronger dorsal spine than the other. 



2. Oreinus plagiostomus, nob. — Schizothorax plagiostomus, Heckel. 

 The breadth of the mouth is equal to a third of the length of the 

 head, and of the interval from the extremity of the snout to the 

 pectoral fins; snout thick, smooth, round and fleshy ; posterior mar- 

 gin of the operculum round. Dorsal spine slender and soft ; colour 

 yellowish brown above, below yellowish white, with a few leprous 

 spots on the body.

The vertical scales at the base of the anal are rather large. 

 The intestines are six lengths of the body, but in young speci- 

 mens, they are only 3^- lengths of the body. The stomach tapers 

 gradually to the intestines, and is about equal to their length. 

 (Griffith.) 



Habitat. Helmund river at GirdunDewar, where they are very numer- 

 ous, and attain the ordinary size of a foot in length. (Griffith MSS.) 



3. Oreinus Griffithii, McClell. — The breadth of the mouth is equal 

 to half the length of the head, and of the interval from the extremity 

 of the snout to the commencement of the pectorals. Dorsal spine 

 large, vertical scales at the anal obsolete, posterior margin of the 

 operculum round, snout smooth.

The intestines are six lengths of the body, and contain a brownish 

 pulp. (Griffith.)
