ADDITIONS AND CORRECTIONS. 



P. 130. Gray-croimied Finch. It is hardly necessary to recognize by name more than one 

 variety of this bird — "campestris" being referred to tephroarjUs proper, and "littoralis" to 

 var. griseinucha. 



P. 135. Baird's Buntinij. As very strongly Iiinted in the text, the supposed specimens of 

 Centronyx bairdii from Massachusetts are not this species at all, but a Passerculus, apparently 

 new. (P. princeps Maynakd, Am. Nat. vi, 1872, p. G37). Although perfectly aware of this at 

 time of writing, I refrained from anticipating publication of the fact. I venture to foretell, 

 that a second specimen of " Centronyx" will never be found. 



P. 13G. St. Lucas Sparrow. Doubtless only a variety of F. rostratus. 



P. 140. Good autliority contends for the specific validity of Feuccea cassinii, but I am not 

 prepared to 3'ield my position. 



P. 147. It may be as well to allow Passerella townsendii to stand as a species, until its 

 intergradation with iliaca is proven. P. schistacea goes with townsendii as a slight variety. 



P. 174, first line. For features read feathers. 



P. 183. Vaiix's Swift. I am more inclined to doubt its validity. 



P. 186. Linne Hummingbird. The implication is, that the specimen accredited to Massa- 

 chusetts came from a dealer's stocls:, in exchange for a specimen of T. colubris spoilt in stufllng. 



P. 207. Ferrugineous Owl. To the extralimital specimens described, add: — No. C15S5, 

 Mus. Smiths. Inst., from Tucson, Arizona, since transmitted to me Jjy Lt. C. Bendire, U. S. A. 

 It is the specimen of which some fragments furnished my note in the American Naturalist, as 

 quoted in the text. 



P. 213. Gyrfalcon. The specimens from the Mackenzie's river region, noticed b}^ Baird 

 (I. c.) under name of F. sacer, have since been determined by Prof. Newton to be indistin- 

 guishable from ordinary var. islandicns. I omitted to state, that var. gyrfalco is a N. European 

 form, not recognized, I believe, from this country. The name sacer has priority over all the 

 others as the specific designation. 



P. 222. Catliartes burrovianus, tliere is reason to believe, may be a valid species ; it does 

 ■not, liowever, occur within our limits. 



P. 248. After Genus Piialaropus insert Brisson. 



P. 270. Before GuuiD^ insert:— Suiioudeb ALECTORIDES. Ck.UvES, E.uls and 

 OTiinR Allies. See p. 241.
