rectrices 5 one of tbem (No. 57835) Las the nape bright golden yellow, the 

 other (No. 54107, Juchitan, Sept. 8, 1868) saffron orange. Both have the 

 outer webs of the primaries largely blotched with white toward the base. 

 As to the females, there appears to be no correlation between the color of 

 the nape and the locality ; those with deep red napes coming, respectively, 

 from liaoul, Coban, and DneQas, Guatemala, and the city of Mexico, 

 those with orange napes from Eastern Mexico (Jalapa and Mirador), 

 Guatemala (lietaluleu), and Western Mexico. Two examples from Hon- 

 duras, in the collection of Messrs. Salvin and Godman, are remarkable 

 chiefly for their small size. The male (San Pedro, G. M. Whitely) is 

 very intensely colored, the white bars of the dorsal region narrower 

 than in any skins from Guatemala or Mexico, and very strongly tinged 

 with fulvous, the lateral and lower poi^tions of the head deep olivedrab, 

 in marked contrast with the white frontal crescent, the white of the 

 rump stained with fulvous-yellow, and the lower parts much deeper 

 olivaceous than other specimens ; the inner webs of the middle rectrices 

 are solid black. The measurements of this specimen are as follows : 

 Wing, 5.00; tail, 3.30; culmen, 1.15; and tarsus, .88. The female (Julian, 

 G. M. Whitely) is of abnormally small dimensions, measuring, wing, 

 4.G0; tail, 2.90; culmen, .95; tarsus, .80. It appears, however, to be an 

 immature bird, and may not have attained its full size. In colors, it is 

 very dark, like the male from San Pedro. 



It is not uncommon for very higbly-colored examples to have the white 

 of the rumj) and upper tail-coverts more or less tinged with yellow.
