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 tlie 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 in a 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, in a 

 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.
