The species of _Naja_ are oviparous, and usually lay some twenty eggs,
elliptical in shape and as large as those of a pigeon, with a soft
shell.
These snakes do not fear the proximity of man, and feed upon rats,
mice, and birds; they seek their prey chiefly in the evening, after
sunset.
They swim extremely well, and frequent the neighbourhood of
water-courses.
Indian legends relate that Brahma, having descended on earth and fallen
asleep one day at high noon, a _Naja_ placed itself in front of him
and, dilating its broad neck, procured for him kindly shade. In order
to repay it for the service rendered, Brahma gave _Naja_ the marks
that it bears on its neck, intended to frighten the kites and other
birds of prey, which are implacable enemies of this snake.
