Hab. — New Zealand. Specimen in Mas. Acad. Philad., and Nat. 

 Mus. Washington. 



A rather strongly marked species comparatively, and in adult plu- 

 mage, or in that plumage represented in the plate of the Voyage of 

 the Erebus and Terror, not difficult to recognize. The bufi' or sienna 

 color in the adult of this bird is darker than in either of the preceding. 

 It is very handsomely and correctly figured in the Zoology of the 

 Voyage of the Erebus and Terror, as above, and is apparently peculiar 

 to the Island of New Zealand. We have before us, twelve specimens 

 of this species from the collection of the Expedition, and from the 

 Museum of the Philadelphia Academy.
