The Slender-billed Shearwater does not appear to have been pro- 

 cured by the Siebold Expedition, but was originally described by 

 Temminck from an example obtained by Mons. Burger in the Sea of 

 Japan. Capt. Rodgers procured it on the east coast of the main 

 island of Japan a few miles north of the latitude of Yokohama 

 (Cassin, Proc. Acad. Nat. Sc. Pliilad. 1862, p. 327). An example 

 was picked up after a storm at Yoshino, Yamato, an inland town in 

 the south of the main island forty miles from the coast (Bakiston 

 and Pryer, Ibis, 1878, p. 218) ; another specimen was picked up 

 much decayed on the beach at Kamakara in Tokio Bay (Blakiston 

 and Pryer, Trans. As. Soc. Japan, 1882, p. 106) ; and there is an 

 example in the British Museum, collected by Captain St. John at 

 Nagasaki in May. 



This Shearwater is said to breed in millions on some of the islands 

 off the coasts of Van Diemen's Land and New Zealand, but is pro- 

 bably a non-breeding summer visitor to the North Pacific.
