Vol 'm9 XVI ] Proposed Changes in the A. 0. U. Check-List. 267 



fLarus hyperboreus barrovianus Ridgway. Larus barrovianus Ridg- 

 way, ' The Auk,' III, No. 3, July, 1886, p. 330 (Point Barrow, Alaska). 

 Reinstated as a subspecies. (Cf. Oberholser, ' The Auk,' XXXV, 

 No. 4, Oct., 1918, p. 472.) Range: northwestern North America, 

 south in winter to California. 



Thalassogeron Ridgway becomes Thalassarche Reichenbach (Naturl. 

 Syst. Vogel, 1852, p. V), because not considered generically separable. 

 (Cf. Loomis, Proc. Calif. Acad. Sci., ser. 4, II, pt. II, No. 12, April 22, 

 1918, p. 44.) 



Thalassogeron chrysostomus culminatus (Gould) becomes Thalas- 

 sarche culminata culminata (Gould), because Diomedea chryso- 

 stoma Forster is considered not with certainty identifiable. (Cf. 

 Loomis, Proc. Calif. Acad. Sci., ser. 4, II, pt. II, No. 12. April 22, 1918, 

 p. 85.) 



Fulmarus rodgersi Cassin becomes Fulmarus glacialis rodgersii 

 Cassin, because not specifically distinct from Fulmarus glacialis. 

 (Cf. Loomis, Proc. Calif. Acad. Sci., ser. 4, II, pt. II, No. 12, April 

 22, 1918, pp. 88-90.) 



Thyellodroma cuneata (Salvin) becomes Thyellodroma chloro- 

 rhyncha (Lesson) (Puffinus chlororhynchus Lesson, Traite d'Ornith., 

 1831, p. 613, no locality), because it is only a light color phase of the 

 latter. (Cf. Loomis, Proc. Calif. Acad. Sci., ser. 4, II, pt. II, No. 12, 

 April 22, 1918, pp. 141-145.) 



fPriofinus Hombron and Jacquiriot. Recognized as a genus. (Cf. 

 Loomis, Proc. Calif. Acad. Sci., ser. 4, II, pt. II, No. 12, April 22, 1918, 

 pp. 59, 108.) The only species therefore should be called 

 Priofinus cinereus (Gmelin). 



fPterodroma gularis (Peale). Procellaria gularis Peale, U. S. Explor. 

 Exped., VIII, 1848, p. 299 (Atlantic Ocean, lat. 68° S.,long. 95° W.). 

 Recorded from Alaska. (Cf. Bent, 'The Auk,' XXXV, No. 2, 

 April, 1918, p. 221.) 



iEstrelata gularis Peale becomes Pterodroma inexpectata (Forster) 

 (Procellaria inexpectata Forster, Descript. Anim., 1844, p. 204, Ant- 

 arctic Ocean), because the latter is identical and of earlier date. 

 (Cf. Loomis, Proc. Calif. Acad. Sci., ser. 4, II, pt. II, No. 12, April 22, 

 1918, pp. 104-105.) 



Pelecanus californicus Ridgway becomes Pelecanus occidentalis 

 californicus Ridgway. {Cf. Oberholser, ' The Auk,' XXXV, No. 1, 

 Jan., 1918, p. 62.) 



Aristonetta Baird, Rep. Expl. & Surv. R. R. Pac, IX, 1858, p. 793 (type, 

 Anas valisineria Wilson). Raised to generic rank. (Cf. Oberholser, 

 Proc. Biol. Soc. Wash., XXXI, June 29, 1918, p. 98.) The only 

 species therefore becomes 



Aristonetta valisineria (Wilson).
