APPENDIX. 



The circumstances which necessitate this Appendix being fully set forth la 

 the first 2)aragruph of the Pi'eface to this edition, it only remains to direct atten- 

 tion to the marginal reference numbers, which indicate the exact point in the 

 body of the work where the new matter is to be interpolated. 



(1.) Page 4, Gencs iECHMOPHORUS : 



jE. clarkii is almost certainly only the female of ^. occidentaUs. 



(2.) Page 14, Synthliboramphus wumizusume : 



There appears to be no reason for considering this species as North Ameri- 

 can. (Cy. Stejneger, Proc. U. S. Nat. Mus. ix. 1885, 524.) 



(3.) Page 38, a'. Creagrus is a good genus, and the species following should be 

 called Creagrus furcatus. {Cf. Eidqway, Proc. U. S. Nat. Mus. xii. 1889, 117.) 



(4.) Page 57, Genus FULMARUS : 



The subspecies of F. glacialis are probably reducible to two, an Atlantic 

 and a Pacific form. The older name for the latter is F. roilgersii, which was 

 based upon a very light-colored individual. If this view of the case be correct, 

 F. glacialis glupischa and the more recently described F. g. columba (Anthony, 

 The Auk, xii. April, 1895. 105) become synonymes of F. g. rodgersii, and F. g. 

 minor is a synonymo of F. glacialis proper. It is possible that bad we good 

 series of specimens from all the breeding localities of the species, the above- 

 mentioned supposed forms could be clearly defined; but I have very serious 

 doubts whether their validity can be demonstrated otherwise.

Related to jE. ph(vopygia is ^. hypoleuca, the comparative diagnostic char- 

 acters of the two being as follows : 

 g^. Larger, and darker above; upper tail-coverts grayish duskj-, very abruptly 



white beneath the surface jb. phseopygia. 



(/'. Smaller, and paler above; upper tail-coverts ash-gray, much less abruptly 

 white beneath the suriiice; wing 8.80-9.20, tail 4.50-4.75 (graduated ibr
