pt. 4, 1912, p. 373); and will contain the following North American 
forms now included in the genus Sterna: 
Sternula antillarum antillarum Lesson. 
Sternula antillarum browni (Mearns.) 
Sternula antillarum browni (Mearns). New subspecies. Sterna 
antillarum brownt Mearns, Proc. Biol. Soc. Wash., X XIX, 1916, p. 71

region from California to Peru. 
Sterna fuscata (Linnzus) becomes Onychoprion fuscatus (Linnzus), 
by recognition of the genus Onychoprion Wagler. (Cf. Mathews, Birds 
Australia, II, pt. 4, 1912, p. 388.) 
Melanosterna Blyth, Journ. As. Soc. Bengal, XV, 1846, p. 373 (type, 
Sterna anetheta Scopoli). By recognition of this as a genus (cf. 
Mathews, Birds Australia, II, pt. 4, 1912, p. 395), Sterna anetheta 
becomes Melanosterna anetheta recognita. (Cf. also Stone, Auk, 
XXXIII, 1916, pp. 429-430.) 
Pheebastria Reichenbach, Nat. Syst. Vogel, 1852, p. V (type, Diomedea 
albatrus Pallas). Recognized as a genus (cf. Mathews, Birds Australia, 
pt. 3, 1912, pp. 242-244). Includes the following North American 
species now contained in Diomedea: 
Pheebastria nigripes (Audubon). 
Pheebastria albatrus (Pallas).

is now regarded as a subspecies of Puffinus kuhlii (Boie). (Cf. Banner- 
man, Bull. Brit. Orn. Club, XX XV, 1915, p. 121.) 
Puffinus griseus (Gmelin) becomes Puffinus griseus chilensis Bona- 
parte (Puffinus chilensis Bonaparte, Consp. Gen. Avium, II, 1856, p. 
202; Chile) in so far as records from the Pacific Coast of North Amer- 
ica are concerned. (Cf. Mathews, Birds Australia, II, pt. I, 1912, p.

Puffinus griseus stricklandi Ridgway, in Baird, Brewer and Ridgway, 
Water Birds North Amer., II, 1884, p. 390 (North Atlantic Ocean). 
Revived as a subspecies, for Puffinus griseus from the Atlantic 
Ocean. (Cf. Mathews, Birds Australia, II, pt. I, 1912, p. 96. 
Phaethon americanus Grant becomes Phaethon catesbyi Brandt, Bull. 
Sci. Acad. Imp. St. Petersb., IV, No. 7, 1838, p. 98, in text (Bermuda 
Islands), since the latter proves to refer to the same bird, and is of 
much earlier date. (Cf. Mathews, Auk, XXXII, 1915, pp. 195-197.)
