1. DIGLOSSA. 3 



The genus Diglossa contaius about sixteen species of small Tit-like 

 birds easil}' recognized by their peculiar hooked bill. The}- arc dif- 

 fused over the more northern portion of tlie Neotropical llegion, from 

 Southern Mexico to Bolivia, and are confined nearly entirely to the 

 upland forests above 6000 feet in altitude. They are said to frequent 

 the bushes and trees at the edges of the forests, and to be usually 

 fouud in small parties, ever active in search of insects. 



The nests of two of the species taken by Salmon in Antioquia {cf. 

 P. Z. S. 1879, p. -iOG) were open and cup-shaped. The eggs (pp. cit. 

 pi. xlii. fig. 1) are spotted with brown on a greenish ground.
