-92- He says the "species certainly occurs in Polynesia", but he gives no other record. Puffinus obscurus (Gmelin). (Type locality: Christmas.) Christmas: Latham. No recent record, and Mathews suggests it may occur only in the breeding season. He refers to it under the name P. lherminieri di- chrous Finsch & Hartlaub. Puffinus nativitatis Streets. (Type locality: Christmas.) Christmas: Streets, breeding in January. Puffinus "chlororhynchus" = pacificus, subspecies. Loomis (Auk, 1919, 487) says it has been obtained on the Fanning Islands, though Wiglesworth does not record it from this group. Possibly it is one of the preceding, under another name. Pterodroma alba (Gmelin). (Type locality: Christmas.) Christmas: Latham (ex Banks collection); Streets. Loomis (Auk, 1920, 88) identifies this species with Procellaria parvirostris Peale, after comparing two specimens from Christmas Id. (collected by Streets) with the descriptions given by Latham and Gmelin, though a series from here and from the Tuamotus (the type locality of parvirostris) may prove them to be different. Streets found "parvirostris" breeding in January, with eggs. STERNIDAE. Onychoprion fuscatus (Linnaeus). Sooty Tern.
