450 INDIAN CYPRINID. 
It remains to express my obligations to those who have assisted the 
object of the foregoing paper. 
To WILLIAM GrirrFitH, Esq., M. A.S. &c. Madras Medical Service, who 
aided me in my collections since 1835, and is still mindful of this though 
engaged in other services of higher interest to science, I have been indebted 
for many species hitherto unknown from countries only visited by himself, 
and which were preserved under difficulties and privations that would have 
deterred an ordinary naturalist from the attempt, especially in the midst of

To B. H. Hopeson, Esq. M. A.S. &c. Resident at Nipal, I have been 
indebted for a small collection of Cyprins deposited in the Asiatic Society ;

am I indebted for the drawings of scales forming the last two plates. 
To Doctor Macteop, Inspector-General of Her Majesty’s Hospitals in 
Bengal, I have been indebted for several collections from different parts of 
India, comprising many species previously unknown. 
To Capt. Simon Fraser Hannay, I am indebted for several species

the difficulty of preserving them in this climate. 
I am also indebted to Captain Francis JENKINS, M. A. S. &ce. Com- 
missioner of Assam, for similar favours, as well as for other facilities afforded 
to my pursuits. 
To Captain RicHarp Lioyp, M. A.S. Indian Navy, who had already 
rendered a high service to ichthyology by the facilities afforded to Dr. Cantor 
while under his command, I am indebted for several small collections of fishes 
from the Tenasserim coast. 
To R. B. CumMBERLAND, Esq. Bengal Medical Service, I am also indebted 
for a small collection of fishes from the Cuttack district : and, lastly—
