Art. XII. — On a Partially White Form of Piiffrmis grisens Gmelin. 



By D. L. Poppelwell. 



[Bead before the Otago Institute. 12th June, 1917 ; received by Editors. 22nd December, 



1917 : issued separately, 24th May, 1918.] 



Albinism of a complete or partial nature has several times been reported 

 in connection with New Zealand birds, but the cases of its occurrence are 

 not so frequent but that they should be recorded. On the 26th April, 1916, 

 when returning from a trip to Stewart Island, I was shown by Mr. John 

 Smith, of the Bluff, a live specimen of a mutton-bird (Puffinus griseus) 

 which showed partial albinism. This interesting specimen was captured 

 by Mr. Smith on Piko-mamaku-iti, the most northerly of the Titi Islands, 

 where Mr. Smith was mutton- birding. The bird was a young one, and was 

 caught in a nest. It was almost fully fledged. The head, neck, and upper 

 part of the breast of this interesting specimen were pure white, back and 

 upper part of the wings partly black, abdomen brown, the tail white. The 

 bird, as mentioned above, was a young one, and in parts still had the 

 down attached. Its beak was of a pinkish white, its legs pink, and its eye 

 greenish. I examined the bird closely, and took certain measurements 

 and other particulars, which were as follows : —

Note. — The above measurements are, I believe, correct; but, as the 

 bird was alive and resented handling, some difficulty was experienced in
