DIGLOSSA PLUMBEA Cabanis. 



COSTA RICAN DIGLOSSA. 



Adult male. — Above plain deep l)lui,sh .slate color, darker (bluish 

 slate-black) on pileiuii, paler (bluish slate-gra}' or deep plumbeous) on 

 rump; remiges and rectrices black with bluish slate-g-ray edgings; 

 lores black; sides of head otherwise like pileum, but rather darker; 

 under parts plain slate-gray, paler on abdomen; maxilla brownish 

 black; mandible light brownish basally, dusky terminally; legs and feet 

 horn brownish (in dried skins); iris brown; length (skins), 105.4-110.2 

 (107.7); wing, 53.8-55.4 (51.9); tail, 39.6-11.5 (12.7); exposed culmen, 

 9.9-10.7 (10.2); tarsus, 17.5-18.8 (18); middle toe, 11.2-12.2 (11.1).' 



Adult female . — Above deep olive-gray or grayish olive, the rump 

 more grayish; under parts deep olive-grayish, paler and tinged with 



* The single Guatemalan specimen, an adult male, differs decidedly from all the 

 adult males from INIexico (eleven in number) in having the entire throat siate-gray 

 and the axillars and under wing-coverts pale buffy or rusty whitish instead of being 

 of the same deep rufous-cinnamon color or russet as the under parts. According to 

 Dr. Sclater, however, "Guatemalan specimens have less plumbeous on the throat, 

 thereby approaching D. sittoldes." Evidently, therefore, Guatemalan specimens 

 require careful comparison with Mexican examples. 



* Four specimens.
