The Cobras (_Naja_) are widely known, alike from the virulence of their poison, and for their remarkable dilatable disk or "hood" on the nape, the ribs which support this hood being much elongated. Two species are commonly recognised, the Cobra di capella of Southern Asia (_Naja tripudians_), and the Asp (_N. haje_) of Africa; but there are marked local varieties of both species, and the _N. sputatrix_ of the Malay countries should probably be recognised as a third species. Those of India, with Ceylon, have a mark like a pair of spectacles upon the hood, while those of Burmah and the neighbouring countries eastward have only an oval black spot upon it. In India the commonest colour of this formidable reptile is uniform brown, though many are of a pale yellowish straw colour, and there are others of every shade between that and black. It grows to a length of about five feet, seldom more. "Almost every writer on the natural productions of the East Indies," remarks Dr. Günther, "has contributed to the natural history of this Snake, which has been surrounded by such a number of fabulous stories, that their repetition and contradiction would fill a volume." It is very generally diffused over the Indian region, though, as Mr. Theobald notices, from its nocturnal habits it is less often seen than many harmless species. "This Snake is, I believe," he adds, "of inoffensive habits, unless irritated, but is, of course, a dangerous neighbour to have in a house.[13] Not only in Burmah, where the respect for animal life is greatest, but in India also I have known a Cobra enticed or forced into an earthen jar, and then carried by two men across a river, or some distance from the village, and liberated. Dr. Günther remarks that, 'singularly enough, it has never been obtained in the valley of Nepâl.' This is very easily accounted for," continues Mr. Theobald, "since few would venture to kill a Cobra, even for scientific purposes, in the rigorously Hindu state of Nepâl. In British India, decent Hindus will not kill a Cobra; and if one has taken up his abode in a house, he is permitted to remain, or else carefully inveigled into an earthen-pot, and carried away as described. Of course only the orthodox Hindu is so careful to abstain from injuring the Cobra, and their reverential feeling is now perhaps rather the exception than the rule, though probably as strong as ever in Nepâl." A fine example of the still more formidable gigantic Cobra (_Hamadryas elaps_), to be noticed presently, was obtained from an earthen pot which had floated out to sea. [13] Although the _Cobra di capella_ is so plentiful in India, we could never hear of one instance of a European being stung by one during a residence of more than twenty-one years in that country. They prey chiefly on Rats, the presence of which is the attraction which brings them about human habitations; and they also prey occasionally upon young chickens, and commonly upon Toads.--ED.
