Genus ARTAMIDES 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 plumage is gray, 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.
