ON THE GENERA. 
XXXI 
1. Genus Capito. 
Characteristics .- Bill compressed, inflated at the base; gonys slightly raised towards the 
tip; cnlmen flat; rictal bristles few and feeble; nostrils rounded and basal. Wings 
rounded and moderate in length; fourth and fifth quills longest. Tail about one-third less 
an the wing m length. Legs and feet similar in structure to the other subfamilies’, 
arsus about the same length as the exterior front toe. According to Mr. Sclater, the 
Baibets occupy but a limited area in South America, compared with many other of its 
peculiar families. Not one of them has yet been found to the north of the Isthmus of 
I anama, or south of the basin of the Amazon ; and the species are chiefly confined to the 
countries traversed by the upper branches of this river and to the mountain- valleys of New 
'ranada, Ecuador, and Peru*. We have few details recorded concerning their habits; but 
they are said to be seen generally in the fruit-trees, feeding on the fruit and hopping from 
blanch to branch like the Toucans. 
Mr. Bartlett, who had great opportunities of noticing the habits of this genus, says that 
iey perch on the tree-tops, and bow the head and raise the tail as they utter their call, 
e considers that their movements greatly resemble those of the Bamphastida. 
the species of this genus have this peculiarity, which exists in no other, namely that 
he sexes differ in a most wonderful manner: for many years the small green ones were all 
considered good species, until Mr. Salvin discovered that they were only females of the red-
