372 CHECK-LIST OF NORTH AMERICAN BIRDS. 



Family BUTEONID^. 



Buteo codperi Cassin. Cooper's Henhawk. [14.] 



Buteo cooperi Cassin, Proc. Acad. Nat. Sci. Phila., 1856, 253. (Near 

 Mountain View, Santa Clara Co., California.) 



Only known from the type specimen, obtained by Dr. J. G. Cooper, 

 near Mountain View, Santa Clara County, California, in October, 

 1856. The validity of the species is in doubt; possibly the light phase 

 of B. harlani. (Cf. Ridgway, Auk, I, 1884, 253, 254; II, 1885, 165, 

 166.) 



Family IGTERID.£. 



icterus icterus (LiNN.a;us). Troupial. [16.3.] 



Oriolus icterus Linnaeus, Syst. Nat., ed. 12, I, 1766, 161. (Cayenne.) 



The only alleged North American occurrence of this South American 

 species is Audubon's record for Charleston, South Carolina. The 

 only specimen stated to have been taken may have been an escaped 

 cage bird. 



Family FRINGILLID.S. 



Ac&nthis brSwsteri (Ridgway). Brewster's Linnet. [17.] 



Mgiathus {flavirostris var.) brewsterii Ridgway, Amer. Nat., VI, July, 

 1872, 434. (Waltham, Mass.) 



Known only from the type specimen, taken at Waltham, Massa- 

 chusetts, November 1, 1870. Possibly a hybrid between Acanthis 

 linaria and Spinns pirrns. 



Spiza t6vnsendi (Audubon). Townsend's Bunting. [18.] 



Emberiza townsendii Audubon, Om. Biog., II, 1834, 183. (New Garden, 

 Chester Co., Pa.) 



The type specimen, taken May 11, 1833, at New Garden, Chester 

 County, Pennsylvania, by Mr. J. K. Townsend, remains unique. Its 

 peculiarities cannot be accounted for by hybridism, nor probably by 

 individual variation.
