Nanina silcrigallensis, Nevill ; Bengal, Behar (Hand-list, p. 28). 



Selix climacterica, Benson ; Assam hills, Burma. 



Euplecta vidua, Assam bills. 



Nanina austeni, W. Bl. ; Garo hills, Assam. 

 faleata, W . B\. ; Garo hills, Assam. 



Helix ornatissima, Benson ; base of Himalayas, Sikkim and Nipal. 



Helix serrula also probably belongs bo the same genus. About S. 

 aneeps and its near ally, H. arata, I am more doubtful ; for there are shell- 

 lobes to the mantle in the former, and the teeth of the odontophore differ 

 in several particulars.* 



As regards H. indica (Pfr. nee Benson), S. sliiplaiji, and H. acuducta^ 

 I cannot now find the notes I made many years since on the animals, but 

 I believe they belong to the forms allied to Ariophanta, in which the foot 

 is broad with the sole undivided, and there is no projecting lobe above tlie 

 caudal gland. The shells present much resemblance to the t^'pe of Albers' 

 section Thalassia. B.. tugurium and S. camura from Sikkim are still more 

 like R. sulmgata from Australia, the type of Thalassia.
