ORNITHOLOGY. 



the great divisions of the globe, and those of Australia, and many 

 other localities in the Pacific Ocean. To American naturalists it is 

 especially interesting, from the fact that it was observed by Dr. Town- 

 send, on the coast of Oregon, whose specimens were described by Mr. 

 Audubon, as above. 



The only specimen in the collection of the Expedition is labelled 

 as having been obtained on the coast of Oregon.

We find in the collection a single specimen in immature plumage, 

 and which is quite identical with the young of P. mollis, of which 

 numerous specimens, including those of Mr. Gould, are in the Museum 

 of the Philadelphia Academy. The present specimen appears to have 

 been obtained further south than this species had been previously 

 noticed. 



Mr. Peale mentions it as follows : 



" This bird was found amidst icebergs, buffeting the storms and 

 fogs of the Antarctic regions. We saw but few of them, and obtained 

 but a single specimen, on the 21st of March, while the Ship Peacock 

 was enveloped in a fog, latitude 68° S., longitude 95° W. of Green- 

 wich. Their flight was easy and not very rapid. They were silent, 

 and alighted on the water to examine some slips of paper and chips 

 purposely thrown from the boat." 



* "Color above cinereous-brown; tail and breast plumbeous; throat, under wing- 

 coverts, and under tail-coverts, white ; primaries and spurious wings nearly black, with 

 brown shafts; tail light beneath; the two outer feathers mottled with white; all the 

 shafts brown above, and white beneath ; the whole plumage white at the roots ; bill 

 blue-black, much curved, very sharp-pointed, and much compressed near the tip ; first 

 tjuill longest. 



" Total length thirteen inches ; extent of wings thirty-four inches ; wing, from the 

 carpal joint, ten and a half inches ; bill one inch ; nasal tubes three-fifths of an inch ; 

 tarsi one and one-fifth inches; outer toe one and six-tenths inches; tail three and four- 

 tenths inches ; outer feathers two and seven-tenths inches. Male." Peale, as above.
