There is another dangerous snake, called “yellow snake” by the colonists, and “Jaruk” by the Yas natives: it attains a large size, and has the reputation of being very venomous, the bite producing almost immediate death.[80] The most deadly snake in appearance, and I believe also in effect, is one of hideous aspect, called by the colonists the “death adder,” and by the Yas natives “Tammin,” from having a small curved process at the extremity of the tail, or, more correctly, the tail terminating suddenly in a small curved extremity, bearing some resemblance to a sting, it is considered by popular rumour to inflict a deadly sting with it. This hideous reptile is thick in proportion to its length; the eye is vivid yellow, with a black longitudinal pupil; the colour of the body is difficult to be described, being a complication of dull colours, with narrow, blackish bands, shaded off into the colours which compose the back; abdomen slightly tinged with red; head broad, thick, and flattened. The specimen I examined measured two feet two inches in length, and five inches in circumference. It is, I believe, an undescribed species.[81] A dog that was bitten by one, died in less than an hour. The specimen I examined was found coiled up near the banks of the Murrumbidgee river; and being of a torpid disposition, did not move when approached, but quietly reposed in the pathway, with its head turned beneath the belly. The “diamond snake” is handsome, attains a large size, and I believe is not considered venomous. It is said, that when cattle are bitten by a venomous snake, they resort immediately to the water. A cow was found lying dead near the river, at “Gudarigby,” during the time I visited the farm, and from appearances the body presented, the stock-keepers formed an opinion that its death was produced by the bite of a venomous snake. Leeches are abundant in all the “water holes” about this part of the colony, and are used for medicinal purposes: they are of a black colour, with longitudinal orange lines extending the whole length of the body, the abdomen being of a dark orange colour. They are in great demand at Sydney, as few or none are found in its vicinity.
