CE. leucoptera similis : pileo nigro : dorso clare cinereo : subalaribus et axillaribus, 

 remigibusque intus, pure albis, fascia subalari marginali interrupta nigra. 



This small Fulmar is allied to CE. leucoptera, and resembles it in having a black head, 

 contrasting with the blue-grey back, but the black does not extend over the sides of 

 the neck ; the under wing-coverts and axillaries, as well as the quill-lining, are pure 

 white, with an interrupted marginal band of black. 



It was originally described by Dr. Stejneger (I.e.) from a specimen obtained in 

 the Province of Mutzu, in the Island of Hondo, and preserved in the Science College 

 Museum of Tokio. He compares it with CE. brevipes, but I consider it more closely 

 allied to CE. leucoptera, and Salvin, who never saw a specimen and copied Stejneger's 

 description, also located the species in the same vicinity. I am the more confident 

 that this affinity is correct, having examined two specimens lent me by the 

 Hon. Walter Rothschild, and obtained on the Bonin Islands by Mr. Owston's 

 collectors. 



Nothing has been published regarding the habits of this species. 



Adult. General colour above fight bluish-grey, with distinct whitish edges to 

 the feathers ; scapulars slaty-grey, with black tips, the longer scapulars conspicuously 

 black at the ends, and resembling the wing-coverts ; lower back and upper tail-coverts 

 bluish-grey, with a patch of blackish feathers on the rump ; the grey upper tail-coverts 

 white at the extreme base and edged with white at the tip ; all the lesser and marginal 

 wing-ooverts black, the median coverts slaty-grey, with black edges ; greater coverts 

 lighter and of a more bluish-grey, with narrow white margins ; bastard wing, 

 primary coverts and quills black, the quills ashy-grey on the inner webs, which have 

 a long wedge-shaped white mark ; the secondaries bluish-grey, white on the inner 

 webs, and fringed with white at the tips, the innermost secondaries dusky-black ;
