466 a (Appendix). Rallus obsoletus, Ridgw.—This proves to be quite 
distinct from R. elegans, being, in fact, more nearly related to R. longi- 
rostris (sive ‘‘crepitans”). 
472. Gallinula galeata (Licht.) Bp.—Quite distinct specifically from 
G. chloropus, Lath. 
473. IONORNIS martinica (Linn.).—This species has usually been 
referred to either Porphyrio, Briss., or Porphyrula, Blyth, but it is exceed- 
ingly distinct generically from both these types, particularly the former. 
The generic name Jonornis, instituted for its special reception, by Reich- 
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 @ (Appendix). Anas fulvigula, Ridgw.—This bird proves very 
distinct from A. obscura. 
526. Pelecanus ERYTHRORHYNCHUS, Gmel.—This name antedates 
“trachyrhynchus, Lath.,” by two years, and, being no less appropriate, 
there is no valid reason why it should not be retained. (Cf. Bull. Nutt. . 
Orn. Club, Jan., 1880, p. 36.) 
525. Sula LEUCOGASTRA (Bodd.) Salvin.—See Salvin, Trans. Zool. 
Soc. Lond., LX, ix, 1875, 496. 
529. PHALACROCORAX DILOPHUS cincinnatus (Brandt) Ridgw.— 
This is simply the large northwestern form of P. dilophus, no more 
entitled to specific separation than var. floridanus, which represents 
the opposite extreme of size. 
In regard to the generic name of the Cormorants, it appears that we 
will have to use Phalacrocorax, Briss., instead of Graculus, the latter, 
properly applied, having for 1ts type the Corvus graculus, Linn., = Gra- 
cula pyrrhocorax, Scop. (Conf. Sharpe, Cat. Passerif. Brit. Mus., p. 146, 
foot-note.) 
547 b. Larus OCCIDENTALIS, Aud. 
548 a. Larus CALIFORNICUS, Lawr. 
549. Larus BRACHYRHYNCHUS, Rich. 
The above appear to be quite well-defined and distinct species; the 
first more nearly related to ZL. affinis, Reinh., than to argentatus ; the 
second much nearer to L. cachinnans, Pall., than to delawarensis. 
581. OSSIFRAGA gigantea (Gmel.) Homb. & Jacq.—A very distinct 
genus from Fulmarus.
