THE NAUTILUS. 115 



I visited the aforesaid Chinaman the next day intending to buy a 

 few more of the shells, but was told that so eager were the Chinese 

 in this city to eat the delicious meat of these shells that all of them 

 bad been sold in a very short time after arriving from the Steamer. 



Not knowing the exact name of this species, I forwarded a few to 

 ray ever-helpful friend, Mr. Wni. J. Raymond of Oakland, Cal., who, 

 comparing them with some of his Asiatic Paludinid(e, found them to 

 be identical with a pair of specimens under the name of Paludina 

 Japonica, Mart. 



While preparing some of the shells for my cabinet, I discovered 

 that each specimen contained inside, from twelve to eighteen young 

 shells, about the size of a small Succmea. 



I have kept two of the larger specimens alive in a tumbler full of 

 Avater, changing it every two or three days, and often putting in a 

 piece of cabbage leaf for them to feed upon. 



A gentleman who recently arrived from Japan, tells me that 

 <3hildren of the poorer classes go out in the rice fields, near Yokohama 

 and gather the shells, selling them for a few cents a quart. 



As this was the first shipment to America of this species alive, and 

 it being also an additional species offered for sale in the markets of 

 San Francisco, I write the above, hoping that the same will be 

 recorded in the "Nautilus" and will be of some interest to its 

 readers. 



DO MOLLUSCA SHOW CHANGE OF CLIMATE IN NEW ENGLAND ? 



BY REV. HENRY W. WINKLEY. 



A few days ago I received from Connecticut a series of shells 

 which I was asked to identify. The specimens being in all proba- 

 bility a species of Goniobasis, I was not only unable to identify, 

 since I know little or nothing of that genus, but also I had never 

 known an instance of that genus being found in New England. If 

 it is common in Connecticut will someone kindly inform me, and if 

 not, may I ask observers if there is a tendency among shells to 

 migrate in a northerly direction ? 



Reasons for the above question are as follows : A change of cli- 

 mate is claimed for New England, said change bringing a warmer
