CARPODACUS MEXICANUS FRONTALIS (Sa^). 

 HOUSE FINCH. 



Smaller than C. to. Tnexicaivus and C. m. rliodocolpus, but larger than C. 

 m. sonoriensis and O. in. ruherrifmis ; in coloration, the adult male inter- 

 mediate between the first named and the rest in extent of the red, this 

 being less restricted and less sharply defined and less intense than in 

 C. TO. mexicanus, the crown, occiput, and back often tinged with red, but 

 rarely to the same extent as in G. to. rhodocolptis, C. in. sonoriensis, and 

 C. in. ruher7'iinus; female rather grayer and more distinctly streaked 

 above than that of C. to. mexicanus.
