Notices of some Land and Fresh Water Shells occurring in Afghanis* 

 than. — By Capt. Thomas Hutton. 



. The following brief notices refer to the Land and Fresh Water Shells 

 procured during the advance of the Army of the Indus into Afghanis- 

 tan in 1839. These of course were collected along the line traversed 

 from Dadur in Cutch Gundava, to Girishk on the Helmund, — but 

 it is by no means intended to restrict the Afghan species to the few 

 herein mentioned, for with the exception of the slight attention which 

 my duties occasionally enabled me to pay to the subject, the country 

 was literally unsearched. Some of the species noticed are scarcely 

 determined to my satisfaction, but in the absence of European speci- 

 mens to compare with them, it was impossible to do more than hazard 

 a conjecture. 



Class. 1 . Gasteropoda. 



Fam HELiciDiE.
