Hah. — Hunan. 



A fine large species, remarkable for its thinness, convex whorls 

 and acute apex. The surface has a somewhat textured appearance 

 (more noticeable in some specimens than others) produced by fine 

 spiral striae crossing the lines of growth. One of these spirals around 

 the middle of the upper whorl is sometimes rather prominent giving a 

 slight subangled appearance. 



6. Vivipara aupiculata, Martens. 



Hah. — T'aoyiian Lsien, also Hung Chiang, Province of Hunan. 



A most instructive series from the above localities showing the 

 connection of the Paludomus rusiosfoma of Gredler with this species. 

 Starting with quite globular specimens every intermediate form is met 

 with until we arrive at the typical auriculated type. Some of these 

 are very large and solid, the finest specimen being 39 millim. in 



Vivipara auriculata Marts. 



length. The more rounded examples (rusiostoma) generally exhibit 

 three more or less distinct zones within the aperture, whereas this 

 part in the typical form is uniformly whitish. Several forms described 

 by Heude under the generic title of Rivularia {Mem. siir la Chine, 

 pi. xl and xli) also appear to belong to this polymorphous species. 



7. Melania baeeata, Gould. 



Hah. — Taoyuen, Hunan. 



Two specimens, one strongly nodosely cancellated, the other 

 spirally costate only.
