46G« (Appendix). EaUus obsolctus. Ridgw. — This i)roves to be quite 

 distinct from R. elegans, being, in fact, more nearly related to R. longi- 

 rostris (siv^e '■'■crepitans'^''). 



472. Gallimila fjaleata (Liclit.) Bp. — Quite distinct specifically from 

 O. chloropus, Lath. 



473. loNORNis martinica (Linn.). — This species has usually been 

 referred to either Forphyrio, Briss., or Porpliyrula, Blyth, but it is exceed- 

 ingly distinct generically from both these types, particularly the former. 

 The generic name lonornis, instituted for its special reception, by Keich- 

 enbach in 1853 (Nat. Syst., p. xxi), seems to be the earliest one avail- 

 able. 



488. Anas boscas, Linn.— See Wharton, "The Ibis," Oct., 1879, 

 p. 453). 



489 a (Appendix). Atias fulvigula, Eidgw. — This bird proves very 

 distinct from A. ohscura. 



526. Pelecaniis erythrorhynchus, Gmel. — This name antedates 

 '•Hracliyrhynclius^ Lath.," by two years, and, being no less appropriate, 

 there is no valid reason why it should not be retained. {Gf. Bull. Nutt. 

 Orn. Club, Jan., 1880, p. 36.) 



525. Sula LEUCOGASTRA (Bodd.) Salvin. — See Salvin, Trans. Zool. 

 Soc. Lond., IX, ix, 1875, 496. 



529. Phalacrocorax dilophus cincinnatus (Brandt) Eidgw. — 

 This is simply the large northwestern form of P. dilophus, no more 

 entitled to specific separation than var. Jioridanus, which represents 

 the opposite extreme of size. 



In regard to the generic name of the Cormorants, it aj^pears that we 

 will have to use Phalacrocorax, Briss., instead of Graculus, the latter, 

 properly applied, having for its type the Gorvus graculus, Linn., = Gra- 

 cula pyrrhocorax, Scoj). {Gonf. Sharpe, Cat. Passerif. Brit. Mus., p. 146, 

 foot-note.) 



547 h. Lams occidentalis, Aud. 



548 rt. Larus caxifornicus, Lawr. 



549. Larus brachyrhynchus, Eich. 



The above appear to be quite well-defined and distinct species ; the 

 first more nearly related to L. arffinis, Eeinh., than to argentafns ; the 

 second much nearer to L. cachhinans, Pall., than to dclaaiarensu. 



581. OssiFRAGA gigantea (Gmel.) Homb. & Jacq. — A very distinct 

 genus ft-om Fulmarus.
