This fine Buliminus differs from the only species known from Japan, 

 B. reinianus, Kob., in its smaller size, much more conical spire, broader 

 base, deeper umbilical slit, but principally by its very distinct sculpture 

 consisting of transverse striation and rather irregular spiral lines which 

 together produce a granulose aspect of the cuticle.

The unique specimen of a Buliminus which Mr. F. W. Eastlake 

 has sent me for description appears to differ specifically from B. reinianus 

 in its much more ventricose almost ovate shape and its greater solidity, 

 in having \ a whorl less, the last whorl higher, the lip of the peristome 

 broader, the parietal callus thicker, and the columella not plicate. The 

 specimen being dead and faded, I cannot describe the colour, which is 

 most likely brownish. 



16. Stenogtra (Opeas) pyrgula, A. Adams. 



A single specimen from Onuma, Yeso. I have received the same 

 species from the Nikko mountains, where it was collected by Mr. F. W. 

 Eastlake.

17. Clausilia praba, A. Ad. The localities Utsonoma and Mamada 

 (Nippon) given in my former paper (J. A. S. B. LI, Pt. II, 1882) 

 were inserted by mistake, the species collected there being Cl. tau, Bottg. 

 Cl. proha has only been found on the island of Kiushiu and in the Corean 

 Archipelago.

I find that this form does not belong to the group of Cl. validiuscula^
