NATURAL SCIENCES OP PHILADELPHIA. 327 



This species is dedicated to Commodore John Rodgers, of the United States 

 Navy, under whose command the voyage of the North Pacific Surveying and 

 Exploring Expedition was performed, and through whose liberal and en- 

 lightened encouragement and assistance the naturalists of the expedition 

 were enabled to form one of the most extensive and interesting collections in 

 all departments of zoology ever brought to this country. In all the classes of 

 Marine zoology the collections are especially valuable, and were made under 

 the immediate direction of this accomplished and distinguished officer. 



155. Fdlmakus pacificus, (Audubon.) 



"Kamtschatka Sea, September, 1855. North Pacific Ocean 1 , lat. 40 N., 

 long. 150 W." (Mr. Stimpson.) 



156. Thalassoica glacialoids, (A. Smith.) 



" At sea, lat. 44 48' S., long. 42 54' E., Nov. 14th, 1853. Eyes black, bill 

 black and flesh-colored, the latter fading to nearly white in drying." (Lieut. 

 Van Wyck.) 



157. iEsTRELATA Lessonii, (Garnot.) 



From the South Indian Ocean. A single specimen of this little known spe- 

 cies, quite identical with Mr. Gould's specimen* now in the Museum of the 

 Philadelphia Academy. 



"Taken in the South Indian Ocean, December, 1853, by Dr. Stuart, of the 

 Porpoise. Eyes black, lower part of toes and webs black, upper part white." 

 (Lieut. Van Wyck.) 



158. Majaqueus conspicillatus, (Gould.) 



From the Atlantic Ocean, off the coast of Africa. Quite identical with Mr. 

 Gould's specimens in the Museum of the Philadelphia Academy, and from a 

 new locality for this species, but probably like nearly all its relatives, a 

 great wanderer. 



"South Atlantic Ocean, September, 1853." (Mr. Stimpson.) 



159. Daption capensis, (Linnaeus.) 



From the Cape of Good Hope and South Pacific Ocean. 



160. PcFFiNtJS Kuhlii, Bonaparte. 



From the Cape of Good Hope. Specimens in excellent plumage appear to 

 be the species designated by Prince Bonaparte as above, and differ from P. 

 major as stated by that distinguished author. 



" Taken with hook and line at sea, off the Cape of Good Hope, Sept. 11th, 

 1853. Land distant about fifty miles." (Mr. F. H. Storer.) 



161. Nectris tenuikostris, (Temminck.) 



From Japan. A small dark lead-colored species, very accurately described 

 and figured in " Fauna Japonica." 



"Taken off the east coast of Niphon, Japan, in lat. 36 N." (Mr. Stimpson.) 



162. Thalassidroma Wilsonii, (Bonaparte.) 



" Gulf Stream, off the coast of Virginia, June, 1853." (Mr. Stimpson.) 



163. Thalassidroma melanogastra, Gould. 



From the Cape of Good Hope and the Pacific Ocean. The former seems to 

 be a new locality for this species, and the specimen differs from others in the 

 collection of the expedition in having the throat black. We find, however, 

 similar specimens in Mr. Gould's collection in the Museum of the Philadelphia 

 Academy. 



"Taken in the South Indian Ocean by Lieut. Van Wyck and Dr. Stuart of 

 the Porpoise, December, 1853." (Mr. Stimpson.) 



'Eyes black, male, lat. 40 c 25' S., long. 126 12' E." (Lieut. Van Wyck.) 



"Thirty miles south of the Cape of Good Hope, September, 1853." (Mr. 

 F. H. Storer.) 



1862.]
