156 H. H. Godwin-Austen — Notes on Indian Land Mollusca. [No; 2, 
tropis and pliaeozona, V. Martens, Sasak Taka ; dschulfensis in Persia ; 
and by bactriana , Hutton, from Kandahar ; which carries it close into the 
Himalayan range. Nevill also describes one (mataianensis) from Mataian, 
Sind Valley, Kashmir. 
Helix similaris and bolus which have been placed in the genns 
Fruticicola have, I slionld say, but very slight connection with it. The 
list of species in Planispira and Plectotropis, as given by Geoffrey 
Nevill in the Hand List, will require very considerable revision. In an 
unpublished copy of his Hand List, greatly corrected, which he was good 
enough to give me before his early death, he has put H. huttoni in 
Aegista, a genus of Albers, who placed in it Helix oldhami from 
Burma, a very different form as regards the aperture of the shell. 
Until we know the anatomy of Hurystoma vittata , Plectotropis 
elegantissima and Aegista oculus from China, it is unsatisfactory work 
trying to place these Indian species under any of these three genera; 
and it is very difficult to get hold of the type species in spirit. 
Sub-genus Planispira, Beck. 
(Type Zonaria , Muller from Celebes.) 
Hurystoma , Albers (on shell alone), type H. vittata , Ferussac, from 
Madras.

Central India (fig. 40 of MSS. Stol.) 
The remarks which I have made regarding the location of Indian 
species in this genus, applies here to this one. An examination lately 
made of the anatomy of some Southern Indian Shells (and I am expect¬ 
ing some more material) shews that a number of them are very closely 
related, although they do not shew it in shell character.
