Thyellodroma cuneata (Salvin) becomes Thyellodroma chlororhyncha (Lesson) (Puffinus chlororhynchus Lesson, Traité 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.)
†Priofinus Hombron and Jacquinot. 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).
†Pterodroma 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.)
Æstrelata gularis Peale becomes Pterodroma inexpectata (Forster) (Procellaria inexpectata Forster, Descript. Anim., 1844, p. 204, Antarctic 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).
Creciscus coturniculus (Ridgway) becomes Creciscus jamaicensis coturniculus (Ridgway). (Cf. Oberholser, ‘The Auk,’ XXXV, No. 1, Jan., 1918, p. 63.)
†Numenius americanus occidentalis Woodhouse. Numenius occidentalis Woodhouse, Proc. Acad. Nat. Sci. Phila., 1852, p. 194 (near Albuquerque, New Mexico). Revived as a subspecies. (Cf. Oberholser, ‘The Auk,’ XXXV, No. 2, April, 1918, p. 191.) Range: southwestern Canada and the northwestern United States, south in winter to Mexico and Jamaica.
Ectopistes migratorius (Linnæus) becomes Ectopistes canadensis (Linnæus) (Columba canadensis Linnæus, Syst. Nat., ed. 12, I, 1766, p. 284, Canada), because the latter has been identified as the same species, and has anteriority. (Cf. Oberholser, Science, N. S., XLVIII, No. 1244, Nov. 1, 1918, p. 445.)
Polyborus cheriway (Jacquin) becomes Polyborus cheriway auduboni Cassin (Polyborus auduboni Cassin, Proc. Acad. Nat. Sci. Phila., 1865, p. 2; Florida), because the North American bird is subspecifically distinct. (Cf. Bangs and Noble, ‘The Auk,’ XXXV, No.4, Oct., 1918, p. 443.)
