lIOLLrSCA. OF INDIA. 339 



close to base of sutural tube, swelling at once towards tbo aperture, 

 which is circular, with a nick or angle on the upper inner margin ; 

 peristome simple, double, reflexed, curving on the columellar 

 margin side. 



Size: maj. diam. 3-4; alt. axis 1-7 mm. 



This has a close resemblance to A. lenticulus, but it differs in its 

 general shape and the aperture from that species obtained in the 

 neighbourhood of Darjiliug, two examples of which I have given 

 figures of.

This single specimen having been sent to me from the Indian 

 Museum, Calcutta, I was able to compare with the type and 

 determine as above.

Specimen figured came from the Rechila Peak, in the Western 

 Bhutan Hills, south of Sikhim (No. 1253 B.M.). A typical speci- 

 men was received by me from Mr. Henry Blanford, and is now 

 in the B.M. Collection, No. 2506.

" Of all the Ali/ccei yet discovered with plicate peristomes, this 

 exhibits the character in the most exaggerated degree ; the free 

 portion of the lip being prolonged into 5 digitiform folds nearly a 

 millimetre in length. The ridge-shaped fold between the two 

 constricted portions is very abrupt, as in Alycceus pHectoclieilus^
