also found in the same river; namely, G. limnophilus, G. bicolor 

 and pangusia, as well as Opsarius baicala, Systomus sophore, 

 immaculatus, and chrysopterus, together with two species of 

 Perilimpus ; namely, P. Sutiha and ostreographus. Pimelodus 

 rita has also a wide circulation in this quarter, having been 

 found by Mr. Griffith in the Khybur Pass, in the Chenab, 

 and in the Cabul river. Pimelodus aor, Buch. has been found 

 also by Mr. Griffith to be one of the characteristic fishes of 

 the Indus, as well as of the Ganges above Seharanpore, but 

 disappears in Affghanistan. Jellalabad is the farthest limit 

 to the north-west to which the species of Hindustan extend. 

 Two species of Ophicephalus are found there, and which are 

 unknown in Bengal, and also a Cirrhinus, which has been 

 named in honour of Sir A. Burnes, from whom Mr. Griffith 

 received every assistance in his pursuits. A similar compli- 

 ment has also been paid to other officers to whom Mr. Griffith 

 was also anxious to acknowledge similar obligations. The 

 Ophicephalus wrahl and Morulius, Buch. both occur at 

 Loodianah, and indeed there does not appear to be any great 

 difference between the fishes of the Indus and those of the 

 Ganges. The species in both rivers appear to be generally 

 the same where the currents are alike, but some species ap- 

 pear to be more developed, both in regard to size and number 

 in one river, than in the other. 



The Herbivorous Cyprins and Pimelodince being the charac- 

 teristic species in the lower parts of those rivers just above 

 the influence of the tides, while the large scaled Barbels be- 

 gin to appear and form the characteristic species as the 

 currents approach to rapids with gravelly bottoms. In the 

 higher parts of the plains, the Nepura or Gobio malacostomus* 

 is the only herbivorous species of Cyprinidce that can be said to 

 be at all common, their place being supplied by Opsarions as 

 that of the Cirhins is supplied by the large scaled, and for 



* Cyprinus falcatus, Gray, Hard. Illuit.
