Indeterminable are the following references, usually referred to P. 

 obscurus : — 



Puffinus obscurus, Schleg. Vog. van Nederl. p. 585 (perhaps P. 

 assimilis, G.) ; id. Eev. Crit. p. cxxxiii (" Nordliches Europa!"). 



Nectris obscura, Keys. & Bias. Wirbelth. Eur. p. 94 (" Mittelland- 

 isches Meer, Siidkiiste Nordamerika's"). 



Puffinus obscurus, Linderm. (Vogel Griechenl. p. 1/1) and Kriiper 

 (Journ. f. Orii. 1863), belongs to P. anglorum, Ray, or the hardly 

 different Mediterranean form P. yelkuan, Acerbi. 



Puffinus obscurus, Gould (B. Eur. pi. 444), we have had no oppor- 

 tunity of comparing. 



Puffinus assimilis, Gould, P. Z. S. 1837, p. 186 ; id. B. of 

 Austr. vii. t. 59; Beichb. Schwimmv. f. 2600 (ex Gould); Gray, Gen. 

 of B. iii. p. 647 (syn. P. nugax, Sol. MS.).

Like P. obscurus, but smaller ; the under tail-coverts also uniform 

 white ; but the while of the underparts mounts up on the sides of the 

 head, including loreal and auricular regions ; tarsi greenish yellow, 

 webs bright chrome-yellow. 



In the Pacific seas of Australia and New Zealand. 



[I was wrong in my note (cited above) in stating this to he the true 

 P. obscurus, Gniel. — F.] 



[In the Royal Museum at Munich I have examined two specimens 

 of a. Puffinus from Madeira, brought home by H.G. the Duke of 

 Leuchtenberg, which apparently belong to this species. They agree 

 very well with the characters noticed above. The under tail-coverts 

 are white, only the lateral ones at the base of the outer web dark, but 

 this hidden. — F.J 



Puffinus auduboni, Finsch. 



Puffinus obscurus, Audub. Syn. B. N. Am. 1839, p. 339 ; Baird, 

 B. N. Am. p. 835 ; Coues, Proc. Acad. Phil. 1864, p. 137 ; Licht. 

 Nomencl. p. 100. 



Like P. assimilis, but the under tail-coverts fuliginous-black ; the 

 anterior lateral under tail-feathers are on the outer vane black, on the 

 inner white; the white on the sides of the head extends, as in P. as- 

 similis, not below the level of the eyes ; bill deep leaden blue ; feet 

 and legs coloured as in P. anglorum. 



This species inhabits the Atlantic Ocean, occurring not unfre- 

 quently along the shores of the Southern United States and in the 

 Gulf of Mexico ; it is abundant in the Bahamas and Bermuda.
