BANGS AND PENARD: SOME CRITICAL NOTES ON BIRDS. 35 



Tanagra aurcata Vieillot becomes the name by which this species 

 must be known. We recognize three geographical races, as follows : — 



1. Tanagra aureata aureata Vieillot. 



A large southern race, with darkest under parts — more chestnut 

 or orange and palest blue crown. Range extending north to Bahia. 



2. Tanagra aureata intermedia (Chubb). 



Euphonia nigricoUis iniermedia Chubb, Ibis, 1910, ser. 9, 4, p. 624. 

 A smaller race, slightly paler below, with a slightly more purplish 

 blue crown. Colombia, Venezuela, and Guiana. 



3. Tanagra aureata pelzelni (Sclater). 



Euphonia nigricoUis pchcini v. Berlepsch, Ms. Sclater, Cat. birds 

 Brit, mus., 1886, 11, p. 61. 



A very distinct race, with yellow under parts (lacking the brownish 

 or orange tinge present in the other two). Western Ecuador. 



Tanagra lauta lauta, nom. nov. 



Euphonia hirundinacea (not Tanagra hirundinacea Lesson, Traite 

 d'ornith., 1831, p. 460 = Cypmagra hirundinacea (Lesson)), Bonaparte 

 Proc. Zool. soc. London, 1837, p. 117 (Guatemala). 



Since there is no name in synonymy available for Bonaparte's 

 Euphonia, which ranges from Mexico to Nicaragua, we propose the 

 above. 



Tanagra lauta proba, nom. nov. 



Phonasca Gnatho (not Tanagra gnatho Lichtenstein, 1830 = Sal- 

 tator atriceps atriceps Lesson) Cabanis, Journ. orn., 1860, p. 335 (Costa 

 Rica). 



The name by which the Costa Rican form has been known also 

 proves to be untenable, and finding no other applied to it, we propose 

 the above.
