CLAUSILIA. 309 



Hob. India: Darjeeling, Sikkiin (Trotter, Stoliczka, Maimvaring, 

 Blanford) ; Bhutan (Blanford) ; Dafla Hills, Assam (Godwin- 

 Austen). 



" Hob. Temperate regions of Sikkim and Butan, in the Eastern 

 Himalayas, from about 5000 to 9000 feet. It doubtless also 

 exists in Nipal. It is generally met with at the roots of oaks and 

 other large trees. 



"In this species, as was noticed by Mr. Benson, the lunule 

 is sometimes broken up into short oblique plaits above, and con- 

 sequently the number of palatal plicae varies. Sometimes there is 

 only the long lamellar plait above the lunule, in other specimens 

 there are, besides the long one, two short plicae." (Blanford.) 



Clausilia ios appears to be one of the commonest species, to 

 judge by the number of specimens in collections. There are shells 

 in the British Museum, presented by Blanford in 1860, which 

 have 10 whorls therefore with one whorl more than Blanf ord's 

 type and measure 13*5x3 mm. .Four specimens in the Cuming 

 collection, also of 10 whorls, attain a length of 14 mm. The 

 Beddome collection is particularly well supplied, as I have counted 

 no less than two dozen : these are from Darjeeling. The species 

 somewhat resembles C. tJieobaldi but it is smaller and the palatal 

 plicae are nearer the aperture.
