ARTAMIDES. 479 



feathers of rump with thickened shafts. In. this family the bill, legs, 

 and nails are black. The nests are built in trees, and the eggs are 

 usually greenish blue, spotted with brown and gray. 



Genera. 



o'. Eill larger and stronger; culmen from base longer than tarsus; wing more 

 than 150 mm.; 23arts of the body-plumage usually more or less barred with 



black and white Artamides (p. 479) 



a". Bill smaller and more slender ; culmen from base equal to, or less than, tarsus ; 

 wing less than 140 mm.; body-phtmage of the adult never barred, with black 

 and white. 

 &'. Much larger; Aving more than 125 nun. 



c'. Wing shorter, about equal to tail ; a black collar, incomplete behind.

. 6". Much smaller; wing less than 125 mm. 



c*. Tarsus shorter and weaker, less than middle toe with claw; rectrices long. 



slender, and strongly graduated Pericrocotus (p. 490)

Genus AETAMIDES Hartlaub, 1865. 



Bill large and strong; wing considerably longer than tail; first primary 

 little more than one-half of second, fourth longest; tarsus strong, longer 

 than bill from nostril; tail nearly square, but outermost pair of rec- 

 trices decidedly shorter than the others. The Philippine species of Arta- 

 mides are very much alike ; the wings and tail are black, and the greater 

 part of the remaining phunage is gi'ay, but certain parts are barred with 

 black and white in nearly all the species. The sexes are unlike and the 

 male is slightly larger than the female. The length is usually more 

 than 260 mm. The key to the species of Artamides is modified from 

 the key given by Grant, Ibis (1896), 535.
