sort of wide-eyed, amazed air that distinguishes thern markedly 

 from other birds. The white feathers are very minute, but 

 quite perfect. This last-mentioned nest was shortly after 

 abandoned by the bird, apparently because it had been dis- 

 turbed-. Another bird was found sitting on an egg on Novem- 

 ber 22, high in the rocks, and some four miles inland." 



Captain Fairchild brought me, in July, a pair in the flesh, 

 which he had shot off Cape Palliser — the first time, as he in- 

 forms me, he has met with the species so far north. The broad 

 white mark which encircles the eyes, except in front, is par- 

 ticularly conspicuous in the male bird ; and the white shafts 

 in the feathers of the tail, which is rather long and acuminate, 

 are a very pronounced feature. Bill ivory-black, with a pale- 

 blue line near the cutting-edge of the lower mandible, running 

 off to a point in front of the terminal expansion ; feet pinkish 

 flesh-white, clouded with grey at the joints, on the interdigital 

 webs, and along the outer edge of the foot ; claws white-horn 

 colour ; irides rich dark-brown. Length, 36in. ; extent of 

 wings, 82-5in. 



CEstrelata cookii, Gray. (Cook's Petrel.) 



I find that the size of this species is variable, a specimen 

 sent to me by Mr. Eeeves, of Mokohinou Island, measuring in 

 the wing, from flexure to the tip, only 8-2in. Bill ebony- 

 black ; legs and feet yellowish-grey, shading into greyish- 

 black on the outer toe ; webs darker. 



CEstrelata lessoni, Garnot. (The White-headed Petrel.) 



Of this rare species — two examples of which, from the 

 Auckland Islands, were exhibited by me at a former meeting of 

 this Society — Dr. Kidder obtained only one specimen on Ker- 

 guelen's Island. On December 29 it was brought home alive 

 by one of the men, having been dug out of a very deep burrow 

 by the dog, at a considerable distance inland, and well up 

 among the hills. He describes the tarsus and foot as flesh- 

 pink, black along upper surfaces of digits and on the web near 

 the claw, and the irides as very dark brown. He states that 

 he saw them following the ship on the 18th January, about 

 seven hundred miles north of Kerguelen, but unfortunately 

 gives us no further particulars. 



Halobeena cserulea, Gmelin. (The Blue Petrel.) 



This species of Petrel, although plentiful in certain localities 

 elsewliere, is very rarely found on the New Zealand coast. 

 Dr. Kidder writes that, " upon first landing on Kerguelen's 

 Island (September 13), the hillsides, apparently quite deserted 

 during the day, became at night perfectly alive with these 

 birds and a species of Palecanoidcs (P. uriiialrix, Gm.), flying
