1842.] Asiatic Society. 469 



other specimens received from Lieutenant Tickell ; and a small banded Gymnodac- 

 tylus, from Afghanistan, nearly allied to a species formerly transmitted to the Society 

 by Lieutenant Tickell from Midnapore, and for which we are indebted to Dr. Thorn- 

 son. This I shall characterize when I come to notice certain others of the Gecko 

 tribe, which I am now trying to collect. 



Pisces. 



For the only specimen of a Fish, the Society is under obligation to Dr. Spry, who 

 has presented us with a small recent example of Zygoena laticeps, Cantor, ('Quar- 

 terly Journal of the Calcutta Medical and Physical Society,' for July, 1837, p. 316, 

 and beautifully figured at p. 318) : it was taken in the Hooghly. 



Mollusca. 



The interesting series of Chusan Shells presented by Dr. Cantor to the Society, 

 have already been enumerated in his letter, and accordingly need only here to be 

 thus briefly mentioned. 



Those presented by M. M. Liautaud and Reymoneng, consist of the following 

 species, of which such as are marked with an asterisk, bear the names with which 

 those gentlemen have favored me : in determining some of the others, I have received 

 the kind assistance of Dr. Cantor : —
