Snakes; Snakes. 46 THE POISONOUS SNAKES OF INDIA. LACHESIS STRIGATUS-The Horse-shoe Viper. Identification.—This is the only species in which the 2nd labial shield is entirely distinct from the lorealpit (see Figs. 27 and 28), and this alone will suffice to establish its identity.

Scales.—Anterior usually 21 (rarely 19); midbody usually 21 (rarely 23) ; posterior usually 15 (rarely 17). Distribution.—The Western Ghats and the Nilgiri, Anamallay, Shevaroy, and Pulney Hills of Southern India, at altitudes from 3,000 to 8,000 feet. Gray mentions it as common about Ootaca- mund, and Jerdon as not uncommon in the wooded parts of the Nilgiris ; but judging from the paucity of specimens in museums, and the written testimony of friends, it appears to me an uncommon snake everywhere. Poison.—-Jerdon* mentions being bitten by one. A ligature speedily applied, followed by suction, warded off any ill-effects, but the skin round the bite blackened in a minute or two, detached itself, and came off in his mouth during suction. Dimensions.—Grows to 1-| feet. Colour.—The prevailing colour is brown, mottled darker to form an irregular coarse variegation. A pale buffer j^ellowish horse-shoe mark on the nape. A dark streak behind the eye. Beneath,light- coloured mottled with darker hues. •Journal, Asiatic Soc, Bengal, Vol. XXII, p. 525-.
