tion make it doubtful whether it should be referred to Helix or 

 Vitrina. No specimen is contained in Mr. W. T. Blanfurd's 

 collection. The single example seen was received by Mr. Theo- 

 bald from Mr. H. F. Blanford, and although uninjured in form, 

 is evidently not in a fresh state. 



7. Helix Calpis, nobis, n. s. 



Testa perforata, ovato-globosa, regulariter oblique subremote im- 

 presso-striatula, polita, lutescente-cornea, lineis spiralibus pallidis 

 cincta ; spira ovato-conica, apice obtuso, sutura impressa ; anfrac- 

 tibus 4 1 couvexis, ultimo ventricoso, antice sensim descendente, 

 verticaliter elongate, ad parietem borizontaliter complanato, circa 

 perforationem excavate ; apertura vix obliqua, verticaliter truncato- 

 ovata, peristomate tenui, recto, margine columellari subverticali, 

 expauso, revoluto-reflexo, perforationem satis magnum celante. 



Diam. major. 4, long. b\ mill. ; apert. long. 3, diam. 2 mill. 



Habitat iu valle Rungun, prope Darjiling. 



The form of this shell is very peculiar, and in the adult has a 

 distorted appearance, augmented by the flatness of the parietal 

 region and by the lengthening of the last whorl towards the 

 aperture. The young shell is conoid globose, and is regular in 

 form. Four specimens in different stages of growth, and all 

 more or less injured, were sent by Mr. W. T. Blanford, who 

 thought it was a dwarf variety of my H. radicicola. He states 

 that his largest specimen, found near Darjiling, measured — 

 diam. major 5, minor 4, alt. 6 mill. 



8. Helix Pinacis, nobis, n. s. 



Testa sinistrorsa, late umbilicata, orbiculato-depressa, superne oblique 

 scabre plicato-striata, liris confertis spiralibus, subtus striis obli- 

 quis flexuosis striisque spiralibus decussata, cornea, epidermide 

 fusca, scabra (junioris ad carinam prsesertim bispida) induta ; 

 spira planata, vix elevatiuscula, apice plauato, sutura leviter im- 

 pressa ; anfractibus 7| planulatis, lente et arete accrescentibus, 

 ultimo antice breviter descendente, superne subcarinato, subtus 

 valde convexo, circa umbilicum profundum, perspectivum, coni- 

 cum, compressiusculo ; apertura valde obliqua, lunari, peristomate 

 expansiusculo, reflexo, albido, marginibus callo brevi, laminari, 

 elevatiusculo, sinuato junctis. 

 Diam. major 14, minor 12|-, axis 4^ mill. 



Habitat raro in regione Sikkim in valle Rungun (4000 ped.), necnon 

 prope Pankabari (1000 ped. alt.). 



Nearly allied to H. plectostoma, B., and inhabiting a tract in 

 the vicinity of Darjiling in company with that shell. Much 

 larger than the largest Khasia variety of that species, it is distin- 

 guished by its much wider conical umbilicus, its depressed pla- 

 nulate spire, planate whorls, closer and more conspicuous spiral
