South Island bird they are shorter and softer. As I do not consider this 
slight difference important enough I can regard the kiwi of the North Island 
only as a race or local form,—<A. australis var. mantelli, Bartl. 
I shall give an extensive treatise of the known species of Apteryx in my 
revised list of the birds of New Zealand. 
Apteryx haastii, Potts. 
Judging from the communications on this species sent me by Dr. Haast 
and Capt. Hutton I take it for a good species. I cannot agree with Mr. Potts 
as to a hybridism between A. australis and oweni, because I am sure a hybrid 
of those species would stand in size intermediate between the two, as is the 
case in our Tetrao medius. 
Mr. Potts’ name ought to be preserved for this species, for from Á. 
maxima, Verr., there exists no other source than the simple name, noticed 
first by Bonaparte, without any reference to the Roa-roa. 
The following species are in my opinion worthy no longer to stand 
amongst the list of the birds of New Zealand :— 
Strix parvissima, Hilm., Potts, Trans. N.Z. Inst., IIL., p. 68. 
Halcyon cinnamonimus, Sws.

Anthus grayi, Bp., Hutton’s Cat., p. 13.

Dysporus piscator, Z. 
Graculus carunculatus, Gm. 
Aptenodytes pennantii, Gray. 
Art. XXII.—On the Birds of the Chatham Islands, by H. H. TRAVERS, with 
Introductory Remarks on the Avifauna and Flora of the Islands in their 
relation to those of New Zealand. By W. T. L. Travers, F.L.S. 
[Read before the Wellington Philosophical Society, 11th September, 1872.] 
I Have compiled, from memoranda furnished to me by my son, Mr. H. H. 
Travers, and have written in his name, the following notes of the distri- 
bution and habits of the birds known to belong to the Chatham Islands, 
specimens of the major part of which he obtained during a recent visit to that 
group. The total number of birds mentioned in Capt Hutton’s “ Catalogue
