Dunedin: Printed for the Commissioners, 1865. Octavo, modern binder's cloth, bound with other papers by Buller.
"This copy is from the 1875 reprint of "Transactions and Proceedings of the New Zealand Institute" published in 1869. This volume was reset, in a slightly larger format, with continuous pagination, and without title pages for the essays. Buller's essay is at pp  - 231. A separate copy of this version has been extracted from the 1875 reprint. I think the print run for this reprint was 600 and it is not held as carefully as the original volume- extracted essays of this version are more common." (Ross Galbreath pers com).

[Buller, Walter]. Notes on Herr Finsch's review of Mr Walter Buller's Essay on New Zealand ornithology, 1868. 49-72 pp.
