pinkish-brown colour, and exhibits, more or less distinctly, the ex- 

 ternal banding. The columella is white or pinkish white, and bears 

 a single distinct but not very strong fold exactly in the middle ; 

 and the " lower small one " mentioned by Sowerby does not exist, 

 for neither the specimens themselves nor the figure exhibit a trace 

 of it. The species is rather thick and strong for its size, and consists 

 of five whorls.

 Descriptions of new Species by Montague Fenton. 



[Eeceived September 8, 1881.] 



The present paper gives an account of the Butterflies observed in 

 Hokkaido by Mr. Fenton, together with one or two species subse- 

 quently obtained from other sources. Some of the specimens have
