160 Mr. W. H. Benson on new species of Hulix. 



which I sent to Mr. Cuming, viz. Bithoura (not Bithonia) in the 

 Gangetic Doab, where I first met with it in 1824. It occurred 

 to me in greater abundance in Bundelkhund, and it is found in 

 other places near the river Jumna, and to the south-west as far 

 as Mhow in Malwah and Neemuch. I never met with it to the 

 north and east of the Ganges.

This remarkable species, the colours of which remind the ob- 

 server of some of the Philippine shells, was found by Capt. W. 

 J. Boys, 6th Bengal Light Cavalry, in a marsh between the de- 

 tached hill washed by the Ganges, and the main range at Sicri- 

 gully in Bahar. 



5. H, Infula, nobis, n. s.

Formerly indicated as H. turbinifor^mis, mihi, in the Journal 

 of the Asiatic Society of Calcutta. This name being used by 

 Pfeiffer for another species, I have altered it for one of nearly 

 similar signification. H, Infula occurred to me in 1835 on the 

 leaves of trees and shrubs at the two places above-noted. The 

 animal has a caudal protuberance like Nanina, but no expansion 

 of the mantle, and is whitish spotted with brown, which, appear- 

 ing through the translucent shell, gives the species a beautiful 

 appearance when newly captured. At first sight it appeared as 

 if the coloui's resided in the shell.
