Obs. This species belongs to the " (E. cooki (Gray) " section 

 of the genus (Estrelata, of which (E. dtfilippiana is also a 

 member. It dilfers from all its congeners iu ha\ing a short, 

 stout, wide bill, aud in the almost total absence of white on 

 the inner webs of the outer primary beneath, the under wing- 

 coverts, with the exception of a rather wide margin, being 

 white as well as the axillary feathers.

Hab. New Zealand. 



This is the " Diomedea cauta " of Buller and other writers 

 on New Zealand birds. On comparing my series of speci- 

 mens with one of Gould's types of T. cautus iu the British 

 ]Museum, the differences above pointed out are apparent. 



In coloration this species is apparently greyer on the head 

 and neck, the dark loral mark in front of the eye being very 

 conspicuous. This species, as well as T. cautus, belong to 

 i\Ir. Ridgway^s genus Thalassoyeron, the sides of the culmi- 

 nicorn being nearly parallel to the base and separated from 

 the latericorn by an interval of soft skin. '

This is the " Diomedea cuhninata " of Buller and other New 

 Zealand writers, but it ditiVrs materially from the true 

 Thalassogeron cuhninaius (Gould), a species of Ptidgway^s 

 genus Thulassorjeron, the base of the culminicorn being 

 separated by an interval of soft skin from the latericorn. In 

 this respect the present species is somewhat intermediate 

 between Diomedea and Thalassofjerou, but the base of the
