27. Waxdeeixg Albatkos {Diomcdca cxulans, L.). 



I noticed several individuals from the deck of the " Stella " 

 during my voyage to and from the islands in 1887, and Mr. 

 Bell informs me that it breeds on the Chanter Islands, a 

 gTOup of small rocks on the eastern side of Sunday Island. 



28. MoLLYMAWK (Diomedca melanophrys, Boie). 



This -was plentiful at sea everywhere in the vicinity of the 

 islands, and no doubt breeds on some of the isolated rocks. 



29. Sooty Albatkos (Diomedca fidujinosa, Gml.). 



I noticed a single specimen at sea between Sunday and 

 Macaulay Islands. Other species of this genus no doubt visit 

 the group, but it is difficult to secm-e specimens, and it is not 

 easy to identify them on the wing. 



30. Cape Pigeon {Daption capcnsis, L.). 



Plentiful at sea all round the group — in fact, one of the 

 commonest petrels at the time of my visit in August, 1887. 

 However, Mr. Bell is of opinion that it does not breed on any 

 of the islands. 



.31. Cook's Petkel {CEstrelata cooJcii, Gray). 



Not uncommon during the summer months, arriving about 

 the beginning of November, and leaving again at the end of 

 April. It breeds on Meyer Island, and more sparingly on 

 Sunday Island, generally in company with Puffinus assimilis. 

 It constructs a buiTOw sometimes over a yard in length, de- 

 positing a single pure-white egg at the extremity. Three of 

 these sent to me by Mr. Bell measm-ed 20in. in length by 

 l-5in. in breadth. 



32. (ESTEELATA Sp. 



i am indebted to Mr. Bell for several specimens (most of 

 them immature) of a handsome species of this genus which I 

 am unable to identify. The forehead, back of the neck, and 

 all the under-surface are pure-white ; crown of the head black ; 

 primaries and secondaries black on their outer edges, becoming 

 much paler towards the inner part of the webs ; shoulders 

 and back brownish, each feather tipped with pale-gi-ey ; tail- 

 feathers gi-eyish-brown. Total length, 18-7oin. ; wing from 

 flexure, 12-3in. ; bill, along the curve of the upper mandible, 

 l-65in. ; lower mandible, l-75iu. ; tail, 5in. ; middle toe 

 and claw, 2iu. ; tarsus, 1-oin. Bill black, feet with th& 

 claws and end of the webs black, lower part and tarsi 

 yellowish. Evidently closely allied to CE. lessonii, but 

 differing in the dark colour of the head and in the darker 

 back. Its measurements are very close to those of CE. les-
