This species, the CorypJwsjji mj k.s crt.statii.s of authors, should l)e 

 called CoryphoHplngns eucullatux^ as MiiUer's long-neg'lectcd name has 

 a imuiber of years priority.

 put centrally' slate color; rest of upper surface slate color; tail slate

The above-described specimen, which is the only one sent by Mr. 

 Foster, differs so much from all of* a large series of Arremon poJio- 

 notus with which it has been compared that it seems impossibly identi- 

 fiable with that species. The discrepancies are not such as can be 

 attributed to sex, age, or even to individual peculiarity; the bird is 

 undoubtedly an adult male, and as such has been treated. With species 

 other than pol!oiiotiis it needs no comparison. 



EMBERIZOIDES MACROURUS HERBICOLA (Vieillot). 



Siilvia herbicola Vieillot, Nouv. Diet. d'Hist. Nat., XI, 1817, p. 192. 

 Eiaberizoides herbicola Sharpe, Cat. Birds Brit. Mus., XIII, 1888, p. 769. 



One specimen, an adult female. ''Iris light brown." This form is 

 apparently well entitled to subspecific recognition, for though but little 

 different in size, the almost invariably unstreaked crissum serves 

 for its easy recognition. 



EMBERNAGRA PLATENSIS (Gmelin). 



Emberiza plateiisis Gmei,in, Syst. Nat., I, 1788, p. 886. 



Embernagra platensis D'OiiBKiNy, Voyage. Amer. M^rid., Ois., 1835-44, p. 284. 



The single specimen is rather more grayish above and less buff'y
