86 Mr. W. T. Blanford on Indian Species of Land-Shells. 



Subgenus Dorcasia?, Gray. 



H. similaris, Fer. Thayet Myo, in Pegu ; Dacca, 



H. bolus, Bens. Thayet Myo. 



H. Peguensis, Bens. Pegu. 



H. Huttoni, Pfr. Western Himalaya ; Sikkim ; Nilgiri Hills ; 



Puppa Hill, Ava. 

 H. tapeina, Bens. Khasi Hills (Theobald) ; Pegu. 

 ?H. rotatoria, v. d. Busch. Pegu. 

 H. Akoutongensis, Theobald. Akoutoung, on the Irawaddy, Pegu ; 



Thayet Myo. 

 H. Oldhami, Bens. Arakan Hills ; Ava. 



I doubt much the distinctness of H. sculpturita, Bens., from 

 H. similaris, Fer., of which the first-named appears to be a large 

 solid variety. 



Subgenus Sivella, n. subg. 

 H. castra, Bens. Darjihng ; Balasore in Orissa ; Ceylon ; Arakau 



Hills. 

 H. lychnia, Bens. Singapore ; Nilgiri Hills (H. F. Blanford). 



Subgenus Thysonota *, Albers. 



H. Guerini, Pfr. Nilgiri Hills. 

 H. crinigera, Bens. Nilgiri Hills. 



Subgenus Ganesella, n. subg. 



H. capitium, Bens. Rajmahal Hills, Bengal; Orissa (Theobald) ; 



Ava. 

 H. variola, Bens. Thayet Myo ; Pegu. 



The distinctness of these two species appears very dubious. 



Subgenus Plectopylis, Bens. 



H. achatina. Gray. Molmain. 



H. anguina, Gould. Mergui. 



H. leiophis, Bens. Akoutoung, near Prome, Pegu ; Thayet Myo. 



H. refuga, Gould. Tenasserim Valley (dextral var., Theobald) ; 



Tavoy (sinistral var.). 

 H. plectostoma, Bens. Darjiling ; Khasi Hills (Theobald) ; Arakan 



Hills ; Bassein, Pegu. 

 H. pinacis, Bens. Darjiling. 

 H. retifera, Pfr. Nilgiri Hills. 



Type-specimens of Helix anguina, Gould, in Mr. Cuming's 

 collection, show that the species is quite distinct from H. acha- 

 tina. Gray, with which, however, H. reperctissa, Gould, is iden- 

 tical. 



* Classed by Albers uuder Nanina.
