from The Century Dictionary and Cyclopedia
- n. A venomous serpent of southern India and Ceylon, Hypnale nepa, a viviparous species of the viperine series.
Sorry, no etymologies found.
The effect, however, is not uniformly fatal; a circumstance which the natives explain by asserting that there are three varieties of the carawala, named the _hil-la_, the _dunu_, and the _mal_-carawala; the second being the largest and the most dreaded.
Of ten species of snakes that ascend trees in Ceylon to search for squirrels and lizards, and to rifle the nests of birds, one half, including the green _carawala_, and the deadly _tic polonga_, are believed by the natives to be venomous; but the truth of this is very dubious.
The third is the _carawala_ , a brown snake of about two feet in length; and for the fourth, of which only a few specimens have been procured, the Singhalese have no name in their vernacular -- a proof that it is neither deadly nor abundant.
But Dr. Davy's estimate of the venom of the _carawala_ is below the truth, as cases have been authenticated to me, in which death from its bite ensued within a few days.
