560 On the fresh-water Fishes of India. 



the inferences which have been drawn from a consideration of the 

 deposits in the Gangetic Delta, as detailed in the Third No. of this 

 Journal, are untenable, in as much as they require the present existence of 

 ■primary mountains within thirty miles of Calcutta, which mountains are 

 hiown not to exist ; and yet they could not have been removed within the 

 historical era, in which the theory requires them to have existed ; and 

 arther, because such inferences would assign an age to the recent de- 

 posits of the Indian continent, once at variance with the admissions of 

 geology, and with the recorded facts of history. 



Mussoorie, 30th August, 1841. 



On the fresh-water Fishes collected by William Griffith, 

 Esq., F. L. S. Madras Medical Service, during his travels 

 under the orders of the Supreme Government of India, from 

 1835 to 1842. By John McClelland, Bengal Medical 

 Service. 



Mr. Griffith's travels have put us in possession of two dis- 

 tinct collections of the fresh-water Fishes of India, which from 

 the light they cast on the geographical distribution of these 

 animals, are unquestionably the most important accession to 

 this branch, that it has fallen to the lot of any Asiatic traveller 

 to make. 



These collections consist of specimens found by Mr. Grif- 

 fith during his travels in the Mishmee Mountains, a part of the 

 Himalaya bounding the eastern side of Upper Assam, in 1836 

 and 183/ ; of specimens found by Mr. Griffith in Boutan in 

 1837 and 1838; of collections made by Mr. Griffith himself in 

 the Kasyah Mountains in 1837; and by his collectors in those 

 mountains during the years 1837, 1838, 1839, and 1840, and 

 who are still continued in his service up to the present period. 

 They consist, lastly, of collections made by himself at 

 Loodianah, and on the Indus, from thence to Ferozepore, 

 and from the Indus to Shikarpore, the Bolan Pass to the 

 Helmund, and from thence to the tributaries of the Oxus
