HYPOTHETICAL LIST. 367 



Thyellodroma pacifica (Gmelin). Pacific Petrel. 



Procelluria pacifica CJmelin, Syst. Nat., I, Pt. ii, 1789, 560. (circa, insulam 

 Euopoa aliasque maris pacifica ex. LuiJvim = Pacific Ocean breeding on 

 Kermadec Islands.) 



Specimen procured from a taxidermist laljelled "Van Couver, B. C." (Cf. 

 Jewett, Auk, XLVI, 1929, 224.) 



Priocellai antarctica (Stephens). Slender-billed Fulmar. [87.] 



Fulmarus antardicus Stephens, in Shaw, General Zoology, XIII, Pt. i, 

 Feb. 18, 1826, 236. Based on Procellan'a glacialis Latham, Index Orn., 

 II, 823. (Antarctic Ocean, pretty far to the south, ex Latham.) 



The locality of Townsend's specimen of this southern species as recorded 

 by Audubon believed to be in error (cf. Audubon, Orn. Biog., V, 333, and 

 Stone, Auk, XLVII, 1930, 414.) Appeared in the third edition as P. gla- 

 cialoides and now transfeiied to the Hypothetical List. 



Oceanodroma hornbyi (Gray). Hornby's Petrel. 



Thalassidroma hornbyi Gray, Proc. Zool. Soc. Lond., XXI, 1853, No. 

 251 [July 25, 1854], 62. (Northwest coast of America.) 



The alleged type locality of this south Pacific species is apparently erroneous 

 as no further specimens have been taken in North American waters. 



Macronectes 2 giganteus (Gmelin). Giant Fulmar. [85.] 



Procellaria gigantea Gmelin, Syst. Nat., I, Pt. ii, 1789, 563. Based 

 largely on the Giant Petrel Latham, General Synops., Ill, Pt. ii, 296, 

 locality quoted from Cook, Voyage, II, 205. (in oceano, potissimum 

 australi, circa Staatenland, Terra del Fuego, insulam desolationis, etc. 

 = Staten Island, off Terra del Fuego.) 



The locality of Townsend's specimen of this species of the southern oceans 

 as quoted by Audubon is believed to be erroneous (cf. Audubon, Orn. Biog., 

 V, 320, and Stone, Auk, XLVII, 1930, 414). 



[Phalacrocorax perspicillatus Pallas. Pallas's Cormorant. 



Phalacrocorax perspicillatus Pallas, Zoogr. Rosso-Asiatica, II, 1811, 305. 

 (Bering Island.) 



North American records of this extinct species of the Asiatic coast regarded 

 as unsatisfactory. Dropped from the List in the third edition.] 



1 Priocella Hombron and Jacqiiinot, Comptes Rendus, XVIII, 1844, 357. 

 Type, by monotypy, Priocella garnoti Hombron and Jacquinot = Procellaria 

 glacialoides Smith. 



- Macronectes Richmond, Proc. Biol. Soc. Wash., XVIII, 1905, 76. Type 

 by orig. desig., Procellaria gigantea Gmelin.
