mainland is effected by native craft, which might very easily transport the few molluscs, 
that occur on the islands. 
1. Succinea vitrea Pfeiffer. 
Succinea vitrea, Pfeiffer, Monog. Helic. vol. tv. p. 810; Hanley, Conch. Ind. pl. LXviil. 
figs. 2, 3; Sowerby, Conch. Icon. vol. xvi. pl. 1. fig. 20. 
Hab. Fainu, North Mahlos Atoll; also Minikoi, Laccadive Islands. 
This species was originally described from the neighbourhood of Calcutta, and it also 
occurs at Bombay. It is scarcely separable from S. crassiuscula Benson, another Indian form. 
2. Sitala vagata un. sp. 
Testa obtuse turbinata, minute perforata, tenuis, dilute fuscescens, lineis imcrementi 
tenuissimis obliquis striata, striisque spiralibus minutis supra et infra sculpta;  spira 
mediocriter elata, ad apicem obtusa; anfractus quinque convexi, regulariter accrescentes, 
ultimus ad peripheriam acute angulatus, infra convexiusculus, antice haud_ descendens; 
apertura oblique lunata; peristoma tenue, margine columellari albo, supra paulo dilatato 
et reflexo, umbilicum partim obtegente. 
Diam. maj. 3 millim., min. 23, alt. 24. 
Hab. Minikoi, Laccadive Islands. 
The spiral striation is excessively fine and only visible under a strong lens. This 
species probably occurs on the Indian Peninsula, although I cannot identify it at present 
with any known Indian form. 
3. LHuplecta indica (Pfeiffer), var. malabarica. 
Helix indica Pfeiffer: Reeve, Conch. Icon. vol. vil. pl. LXxxil. fig. 448; Hanley, 
Conch. Indica, pl. Ly. fig. 10. 
Euplecta malabarica n. subsp. Blanford, Proc. Malac. Soc. vol. Iv. p. 250, pl. xxv. 
fig. 5. 
Hab. Fainu, North Mahlos Atoll (Gardiner); Malabar Coastland (Blanford). 
A smaller form than the type of indica, with a more conical spire, more convex 
whorls, and stronger and more granose sculpture. Helix shipleyi Pfr. is another variety of 
this species.
