 tion more rusty above (ground color of back, etc., more tawn}", or 

 with rust}" edgings to black streaks broader), forehead more exten- 

 sivel}' black, and wing-bands less distinct. 



Adult wr^Zf^— Length (skins), 122.68-132.84 (127.51); wing, 67.06- 

 75.44 (72.39): tail, 56.90-64.01 (60.20); exposed culmen, 8.89-10.41 

 (9.91); depth of bill at base. 5.59-6.10 (5.84): tarsus, 16.76-18.03 

 (17.27); middle toe, 11.68-12.45 (12.19).^ 



Adult female.— l^^n^\h (skins), 120.40-133.10 (126.75); wing, 65.28- 

 73.66 (66.29): tail, 55.12-62.99 (60.45); exposed culmen, 9.40-10.41

Southern Mexico, breeding north to Vera Cruz (Cofre del Perote, 

 Jico, etc.), Puebla (Atlixco). Tlaxcala (Apixaco), Michoacan (Patz- 

 cuaro), Jalisco, and territor}" of Tepic; south to Chiapas (San Cristo- 

 bal. September 24); (?) northwestern Guatemala (Sacahaja, department 

 of Cuiche, May 22''). 



(?) Fringilla socialis (not of Wilson) Swaixsox, Philos. Mag., new ser., i., 1827, 



435 (Temascaltepec, Mexico, ^Mexico). 

 (?) Sp.linitesi socialis Caba^^is, Mus. Hein.,i, April, 1851, 1.33 (Mexico). 

 [SpizeUa] socialis Lichtenstein, Nom. Av. Mus. Berol., 1854, 43, part (Mexico). — 

 Sclater and Salvix, Nom. Av. Neotr., 1873, 32, part. 



^ Eight specimens. 



^ Seven specimens, one of them with sex doubtful. 



^ This specimen, in worn breeding plumage, I am unable to distinguish from Mexi- 

 can specimens. It seems probable, therefore, that S. s. pinetorum belongs to the more 

 eastern portions of northern Guatemala (departments of Vera Paz, Peten, etc.), and 

 extending thence southeastward across Honduras.
