This species, which is chiefly confined to the low-lands near the 

 sea-shore, is found beneath decaying vegetation and under loose 

 stones. It may be easily recognized by its small size, subcylindri- 

 cal form, thin texture and pale horn color. The animal is pale 

 yellow.

 be distinguished by its ovate-conical form, whitish or pale fulvous

This charming species, which is not uncommon on foliage at 

 Upolu, maybe distinguished by its white color and spiral opaque-white 

 interrupted lines. The spire is moderately produced, the last whorl 

 ventricose, obliquely produced and the base exhibits a large umbili- 

 cus. The peristome is broadly and flatly expanded. Length 19 

 mill 



Mr. Pease, on the authority of Mr. Brazier cites Tutuila as its 

 habitat.
