Sir Walter Bailer mentions au egg measuring 4-6 b}- 2';j inches. 



In the Bull. B. 0. Club, No. XVII. p. 3(5 {Ibis, 1894, p. 429) it is mentioned 

 that I exhibited before the Club some Kiwis I had received alive, and wliich 

 in addition to the cross-markings, showed lougitndinal lines to the feathers. I 

 concluded that they must be hybrids between A. m'intelli and A. occidentalis ; but 

 I evidentl}' made a mistake about this, as they lost all the mi.xed apj)carance in 

 their plumage, and conld afterwards not be distinguished from ordinary A. oiceiii 

 The mixed markings they showed, when young, were therefore most likely a peculiar 

 aberrational character. The place the.^e Kiwis came from is not known to mo.

Through the great kindness of the Hon. Dr. Walter Rothschild, M.P., I 

 have come into temporary possession of the largest collection of the skeletons and 

 alcohol-preserved bodies of the genus Apteryx that have ever been amassed in 

 one museum. I have been able to study skeletons of Aptfnjx mnntelli {■= A. biilleri), 

 A. haa.iti, A. oweni, A. australis from Stewart Island ; besides these there were 

 two young sjjecimens of A. australis removed from the egg, and bodies in sjjirit 

 of A. mantelli, A. oweni, A. Iiaasti, and A. australis from Stewart Island, and 

 a body from which a skin had been prepared, and which was therefore incomplete, 

 of ^1. occidentalis. 



In addition to this rich material, for the use of which I am greatly indebted 

 to Mr. Rothschild, I have been able to refer to a single skeleton of each of A. oweni 

 and A. australis which belong to the collection under my charge at the Zoological 

 Society's Gardens. 



I am therefore, I believe, in a jiosition to settle more definitely than lias yet
