Dryocopus Boie.* 
Bill shorter than the head, with the base broader than high ; the gonys moderate, and advancing 
upwards; the nostrils basal, lateral, and hidden by the projecting plumes. Wings moderate and pointed, 
with the third, fourth, and fifth quills nearly equal and longest. Tail lengthened and rounded. Tarsi 
short, and covered in front with broad transverse scales. Toes unequal, the posterior outer toe shorter 
than the anterior outer one, the inner posterior toe short ; the claws moderate, compressed, and curved. 
All the species are found ia the New World, except one that inhabits the northern and eastern parts of Europe. 
Tliey arc active birds, flying from tree to tree in search of decayed parts of the trunks and branches, in which they 
extract fi-om beneath the bark, by means of their bills, the insects that destroy the timber. Their movements are very 
rapid, and their flight is powerful, but not prolonged to any distance. They wiU also feed on Indian corn, chestnuts, and 
acoi'ns. The eggs are placed in hollows of the trees, which are excavated by the bhds to the depth of a foot or more, 
with a breadth generally of two or three inches, and enlarged at the cud to five or six inches. The eggs are usually 
four to six in number.

Chrysocolaptes Bhjth.-\ 
Bill as long as the head, broad at the base ; the gonys of the lower mandible lengthened, and advancing

the longest. Tail long, rounded, and very rigid. Tarsi as long as the outer anterior toe, robust, and 
covered with transverse scales. Toes long, slender, the outer posterior toe longer than the anterior outer

India and its archipelago are the countries of the five known species of this genus. They are found in the dense 
forests, especially in those that are situated on the elevated mountains. Their habits do not difi'er from those noticed 
of the other genera of this family.
