the summer of 1833, when the last of them died. 
HELIx INTERRUPTA, Bens. 
Hel. testd sinistrorsd, orbiculato-convexd, infra tumidd, umbilicatd, ad 
peripheriam obtuse angulatd, longitudinaliter confertissimé 
striatd, suprd striis interruptis fasciis transversalibus dispositis ; 
spird apice obtusd ; peristomate tenui acuto. 
Hab. in rupibus umbrosis Sicrigali et prope Gangis ostiorum fluvium 
Jellinghy dictam. 
This shell has been thought to belong to the species called Helix Hi- 
malayana by Mr. Lea (Hel. levipes?), but appears to me to be very 
different when compared with the following characters of a specimen of 
the latter in my possession. 
Hewurx Himatayana, Lea. 
Hel. testé. sinistrorsd, orbiculato-convexd, longitudinaliter rugosd, su- 
pra interstittis rugarum corrugatis, infrd transverse rugosulis, 
tumidd, nmbilicatd: fulvd fasciis plurimis castaneis, majore infra 
peripheriam ; peripherid subangulatd ; labro reflexo, albo. 
The spire is less exserted in this species than in Hel. interrupta, the 
peculiar sculpture of which forms the best distinctive character. 
The angulated periphery in Hel. interrupta shews an approach to 
Carocolla, the animal of which, I conclude from the silence of ob- 
servers, differs in nothing from that of Helix; whereas that of Hel. 
interrupta differs most materially, the excrements being voided from an 
opening in the terminal and posterior part of the foot instead of from 
the foramen commune ! 
The following is a description of the animal taken while I had the liye 
specimens in my possession. 
Tentacula duo superiora elongata capitulis tumidis oculiferis (puncta 
percipientia gerentibus), duo inferiora capitulis parvis tumidis, Pes 
elongatus, compressus, marginatus, supra granulatus, apertura terminali 
anum et membrum carnosum mucorem emittentem continente,
