252 Mr. L. Reeve on the Geographical Distribution of the Bulimi. 



characteristic Bulimi inhabiting this part of Asia arc those of the 

 Himalaya range, B. Kunawwensis, pretiomis, vibex, nivicola, cce- 

 lebs, and arcuatus. Their shells are of a fulvous brown colour, 

 mostly streaked with opake white marks, all of one type, distinct 

 from the Syrian, but sufficiently allied to come into the same 

 province of distribution. Occupying a loftier situation than the 

 species before mentioned, they have, as in Venezuela, stouter 

 shells, but are still comparatively small and sombre. On the 

 mountain slopes, where the flora, represented by the rhododen- 

 dron and juniper, is of a subarctic character, the genus inhabits 

 a much colder temperature in elevation than it reaches in either 

 hemisphere in latitude. Two species, B. arcuatus and nivicola, 

 are found in the Liti Pass at an elevation of 14,000 feet on ju- 

 niper bushes among patches of snow at the hottest period of the 

 year. This is the only locality in which the genus approaches 

 the snow-line. The physical conditions of India below the Emodic 

 or Alpine region of vegetation are not calculated to favour the 

 growth of Bulimi. In the plains there is a scarcity of wood 

 and forest, such as we have noticed to serve so materially for 

 the production of these snails in South America ; and the burn- 

 ing of the thickets in the hill countries for the pasturage of cattle, 

 offers the same obstacles to their growth and increase as the 

 clearing away of the virgin forests in Brazil. 



2. The Malayan Province. 



The Malayan province of the genus, which comprises the 

 islands of the Indian Archipelago, commences on the south- 

 western corner of the Asiatic continent, where it is represented 

 at Burmah by B. Sylheticus and in Siam by B. atricallosus. 

 These species are of a totally different type from any of the Bu- 

 limi of Hindoostan, and agree precisely with that characteristic 

 Malayan type which appears at Java, Timor, Celebes and Am- 

 boyna in B. citrinus, Icevus, contusus, chloris and sinistralis, at 

 Borneo in B. Adamsii, at Ceylon in B. Ceylanicus, and at Min- 

 danao, the most southern of the Philippine Islands, in B. ma- 

 culifer-us. B. fulguratus and malleatus, having an inflated shell 

 with a winding plait upon the columella, represent a type pecu- 

 liar to the Feejee Islands. B. miltocheilus, with a wax-like fusi- 

 form shell and brilliant vermilion lip, from Christoval Island, one 

 of the Solomon's Group, is unique as a type. B. fibratus and 

 Caledonicus with large robust shells of dark chestnut-brown colour, 

 red internally, represent another very distinct type in the island 

 of New Caledonia, but this appears again twelve degrees further 

 south at Auckland, North Island of New Zealand, in the only 

 species inhabiting that group, B. Shongii. It is worthy of notice, 

 that this large stout tropical-looking Bulimus is under the same
