auce in the more fertile parts near the Gulf of Bab-el-mandeb and the 

 Indian Ocean. B. latireflexus, a fine species inhabiting the vicinity of 

 Muskat on the Gulf of Oman, has a polished shell of solid, stony compo- 

 sition, without colour or marking, of precisely the same type as B. labiosus 

 and labrosus of Asia Minor. B.fragosns and Forslcalii inhabiting Yemen, 

 also patternless, assimilate to the tumid tribe of Pupa of Asia Minor. 

 Abyssinia and the neighbouring island of Socotra, marking the eastern 

 boundary of the Caucasian province, contribute two species from each 

 locality, one of which species in both instances belongs to an Indian type, 

 the other being remote from it. B. Olivieri of Abyssinia has an inflated 

 shell, with a dark fibrous epidermis very distinct in character from any 

 Asiatic or European species, while B. Abgssiuicus from the same locality 

 has been collected also in Central India, north of the river Nerbudda. It 

 is allied in form with B. Jerdoni from the hilly districts of the Deccan 

 peninsula, and both species agree in typical character with B.fragosns of 

 Arabia. B. Socotrensis, inhabiting the island of Socotra, off Cape Guar- 

 dafui, has a peculiar little solid pea-shaped shell unique as a type; but 

 dated with it in the same locality is an oblong cylindrical form, B. 

 contiguuSj belonging to a type of Hindoostan, represented by B. pullus, 

 inhabiting the environs of Delhi and Bundelkhund and extending into the 

 Gangetic plains. 



In the south-western countries of Asia the genus is very meagrely re- 

 presented, but the species are peculiar in their circumstances of habita- 

 tion. Two of comparatively large size occur on the hills of Afghanistan, 

 B. Griffithsii and eremita, with opaque colourless shells partaking of the 

 Syrian type. From the whole of Hindoostan, including the Himalaya 

 range, the Punjab, Scinde, Nepaul, Bhotan, Assam, the Deccan, and 

 Carnatic, only five-and-twenty species have been collected, limited appa- 

 rently in number of individuals. In the plains watered by the numerous 

 branches of the Ganges, with a temperature varying in the season of the 

 hot winds from 85° to 90° at night, to 130° or 140° in the sun, the 

 Bnlimi are scattered and of miscellaneous character. On the wooded 

 hills rising into a moist and cooler atmosphere they are more abundant. 

 B. rujktrigatus at an elevation of 4,000 feet has a fulvous, horny, oblong 

 shell. B. cosnqpicttts and tutulns, inhabiting a lower level, are minute 

 delicate brown species, the latter being convoluted in the form of a rounded 

 Cgclostoma. B. pullus is a light cylindrical form, B. cereus and gracilis 

 are thin, horny species, and B. punctatus, Bontice, and Bengalensis have 

 light inflated shells of a type altogether different. The most characteristic 

 Bulimi inhabiting this part of Asia are those of the Himalaya range, B. Ku- 

 uavurensis, pretiosus, vibex, nivicola, calebs, and arcuatus. Their shells are 

 of a fulvous brown colour, mostly streaked with opaque white marks, all 

 of one type, distinct from the Syrian, but sufficiently allied to come into
