above referred to, but if this bird is erroneously designated sulcirostris, 

 the name having priority is that of Mr. Peale, above given. 



This species belongs to the group, probably subgeneric in value only, 

 denominated Haliaeus or Microcarho, by Bonaparte (" Haliaetis, Bp. ex 

 111. Microcarho si videbitur"), Conspectus Avium, II, p. 177. It is 

 one of the smallest species of the Cormorants.

A very handsome small species, much resembling that immediately 

 preceding, and from which we do not feel fully assured that it is dis- 

 tinct. The present specimen is, however, clearly the species described 

 by Mr. Gould, as above. 



According to Mr. Peale : 



" The specimens were procured at the Bay of Islands, New Zealand, 

 where we found them more common than the Purple-throated Cormo- 

 rant, which was also observed there." 



This bird differs from the last mainly in the rather shorter bill, and 

 the lighter colors of its plumage, but in size and other characters, it 

 is quite similar. Specimens in the present collection, and in the Mu- 

 seum of the Philadelphia Academy, have not, to us, the appearance 

 of mature birds. Both this and the preceding species are mentioned 

 by Dr. Pickering as having been observed at the Bay of Islands, and 

 * as frequenting the same description of locality, if not associating 

 together. 



* " Head, neck, and body, dark sepia-brown ; wings dark gray, the primaries very 

 much curved inwards, black, with a greenish gloss ; secondaries and coverts with the 

 usual dark edges ; tail long, slender, rounded, the feathers attenuated at the tip, and 

 pointed, black ; shafts black; bill horn-color; lores and pouch bright yellow; irides 

 brown ; feet black. 



"Total length, twenty-two and six-tenths inches ; wing, from the carpal joint, nine 

 and four-tenths inches ; tail, six and four-tenths inches ; outer feathers, four and two- 

 tenths inches; bill, one and two-tenths inches ; to the corners of the mouth, three and 

 three-tenths inches ; tarsi, one and three-tenths inches ; outer toe, including the nail, 

 two and seven-tenths inches ; nail, three-tenths of an inch ; inner toe, including the nail, 

 one and three-tenths inches; nail, four-tenths of an inch."
