SUBGENUS Centurus SWAINSON. 



Centurus SWAINS. Classif . B. ii, 1837, 310. Type. Picus carolinus LINN. 



GEN. CHAB. Bill about as long as the head, or a little longer, the length from the tip 

 to the nostril about equal to the tarsus, or a little greater; decidedly compressed anteri- 

 orly, but depressed at the extreme base; the lateral groove distinct for half the length of 

 the bill; culmen decidedly but gently curved from the base; gonys nearly straight, and 

 about half as long as the culmen. Nostrils broad, elliptical, situated about midway be- 

 tween the culmen and tomium, and only partly concealed by the frontal tufts. Anterior 

 outer toe a little longer than the posterior, the inner anterior toe decidedly shorter, and 

 the inner hind toe only about half its length. Wings long and broad, third to fifth pri- 

 maries longest, the first equal to the sixth to the ninth. Tail about two thirds as long as 

 the wing, graduated, the feathers (except the outer) rather abruptly attenuated at ends. 

 Colors, banded with black and white, or yellow, above, with more or less of the pileum 

 scarlet in the male; below plain, the abdomen tinged with red, orange, or yellow in most 

 species. 



While only one species of Centurus occurs in eastern North 

 America, two others are found along our southwestern border : 

 C. aurifrons in southern Texas, and C. uropygialis in southern New 

 Mexico and Arizona. Other species belong to Mexico, Central 

 America, Cuba, Hayti, and Jamaica.
