On the vertebrated animals of the Lower Murray and Darling, their habits, economy and geographical distribution. [and] On snakes observed in the neighbourhood of Sydney.
Sydney: Transactions of the Philosophical Society of New South Wales, 1866. Octavo, Publisher's quarter cloth and printed boards, a fine copy contained in a handsome modern solander box, rare.
Both Krefft papers (also published as an author's reprint) are of great interest, the first paper particularly so as it gives an insight into the abundance and variety of animals in southern New South Wales before agriculture took hold. Krefft was the biologist on the Blandowski Expedition and his account of the Pig-footed Bandicoot is the only substantial record of an animal that vanished almost immediately with European settlement.
Other papers of interest are Berncastle, On snake-bites and their antidotes (published in duodecimo form and extremely scarce); Ramsay, On the oology of Australia; and Krefft, On the manners and customs of the Aborigines of the Lower Murray and Darling.
