466 Mr. W.H. Benson’s Conchological Notices. 
the eastern suburb of Calcutta to the Salt Lake at Balliaghat, heaps of 
a Cardita with longitudinal ribs, of a large and thick Cyrena, and of 
Cerithium Telescopium, exposed to the heat of the sun for the purpose of 
effecting the death and decay of the included animals previously to the 
reduction of the shells into lime. 
Early in the month I took specimens of them, and leaving them for 
a night in fresh water I was surprised to find two Cerithia alive. I kept 
them during a fortnight in fresh water, and on the 22nd January carried 
them, packed up in cotton, on board a vessel bound for England. After 
we had been several days at sea, I placed them ina large open glass 
with salt water, in which they appeared unusually lively. I kept them 
thus, changing the water at intervals, until the 29th May, when we 
reached the English Channel ; I then packed them up, as before, ina 
box, and carried them from Portsmouth to Cornwall, and thence to 
Dublin, which I did not reach until the 14th June; here they again got 
fresh supplies of sea water at intervals. One of them died during a 
temporary absence between the 30th June and 7th July, and on the 11th 
July the survivor was again committed to its prison and was taken to 
Cornwall, and thence to London, where it was delivered alive to Mr. 
G. B. Sowerby, on the 23rd July. 
This animal had thus travelled during a period of six months over a 
vast extent of the surface of the globe, and had for a considerable portion 
of that time been unavoidably deprived of its native element. 
It is this individual which has been dissected by the Rev. M. J. Berkeley 
and Mr. Hoffman, whose account of its anatomy is given at page 431 of 
the present Number.
