218 Land and Fresh-water Shells of the Himalaya. [March, 



neft, minutissime granulata, pyramidata, subties plano-convexa, anfrac- 

 tibus septem convexiusculis, ultimo acuto angulato, suturis leviter im- 

 pressis, umbilico evanescente, apertura latiore quamlonga ; apice obtuso." 

 — Axis 0.16. 



Animal Heliciform, greyish, darker on the tentacula. Found on 

 dead leaves at Simla, in the khads, and when in motion carries its 

 shell upright. It is not uncommon, but its smallness renders it difficult 

 to collect.— (H.) 



" It is more lengthened proportionally than either c H. turbinifor- 

 mis' of Patargatha and Berhampore, alluded to in p. 357, vol. 5, 

 of this Journal, or the European species * H. conicd and * convidea.* 

 In size it is much inferior to any of the three. It differs altogether 

 from the two latter in substance and coloring which approach to those 

 of ' H. turbiniformis,' but the animal does not appear to exhibit the 

 beautiful dark patches on a light ground which render that shell so 

 conspicuous, when the animal is alive, by the appearance of the tints 

 through the translucent shell ; and the sculpture is altogether different."

No. 10. Helix bullula, Hutton. — " Testa parvula, glabra, trans- 

 lucente, sub-trochiformi, conoidea; anfractibus quinque convexis, ultimo 

 rotundato ; suturis impressis ; umbilico angustato ; apertura latiore ; 

 labro simplici." — Diam. 015. — (B.) 



Found with the preceding species among dead leaves at Simla, 



No. 11. Helix nana, Hutton. — " Testa parvula, convexo-co- 

 noidea, pallide fuscescente ; anfractibus sex aut septem arete convalu- 

 tis, ultimo rotundato ; apertura latiore, labro simplici ; umbilico evani- 

 olo; apice valde obtuso." — Diam. 0.1, — (B.) 



Animal Heliciform ; color dark-grey, Accompanies the last two 

 species and occurs in the greatest abundance. It is nearly allied to the 

 British species ' H, trochiformis,' (fulva, Draparnaud,) but the more 

 closely wound whorls sufficiently distinguish it. — (B.) 



No. 12. Helix planiuscula, Hutton. — " Testa parvula, depres- 

 sa fusca, polita; anfractibus quinque, ultimi periphaeria rotundata ; aper- 

 tura transversa." — Diam. 0.1. — (B.) 



Found at Simla on dead leaves. — (H.) 



" This shell is darker and smaller than * H. crystallina' of Britain, 

 which has likewise a more flattened apex than the Simla species." — (B.)

 to the genera Clausilia, Pupa, Bulimus, Carychium, Vertigo, and 

 Cyclostoma, together with the fluviatile shells above alluded to.]
