A LIST OF A SMALL COLLECTION OF SHELLS 

 FROM CHINA.

In 1899 Capt. A. W. T. Wingate made a journey across China, on 

 the route collecting Zoological specimens, which he very liberally sent 

 to the Natural History Museum, South Kensington. Starting from 

 Shanghai he ascended the Yang-tse River in a Chinese gunboat as far 

 as Yo-tchau, and thence, crossing the Tong-Ting Lake, proceeded up 

 the Yuen River, across the Hunan and Kwei-chow provinces to 

 Yunnan city, and thence to Bhamo in Burma. The following is a 

 list of the shells obtained on this journey. The most interesting 

 specimens are two series of Melania r/redleri and Vivipara auriculata. 

 The latter especially shows the remarkable variation which occurs so 

 frequently or invariably in freshwater species. Taking the two 

 extreme types of this species, one would never for a moment consider 

 them as forms of one and the same species, yet it seems impossible to 

 do otherwise when the intervening links are studied.
