and its vicinity in Vera Paz we found it not uncommon in February 1862. It here 

 frequents the openings in the forest. In Guiana Mr. Whitely found C. spiza both at 

 Bartica Grove, nearly at the sea-level, and in the Eoraima Mountains, some 5000 or 

 6000 feet above it.

There are only four really recognizable species of Cosreba, so far as we can see, 

 though several others have been indicated, chiefly by Dr. Cabanis. Of these four, 

 C. cyanea and C. ccerulea are found over the whole of the tropical portion of South 

 America, the former penetrating our country as far north as Southern Mexico, and also 

 occurring in the island of Cuba. In Central America C. lucida is found taking the 

 place of C. ccerulea. The fourth species, 0. nitida, is an inhabitant of the upper valley 

 of the Amazons, and Colombia probably on the eastern slopes of the Andes. 



The species of Coereha are all very similar in coloration, the males being deep blue 

 of various shades, and the wings and tail black. C. cyanea is easily recognized from 

 all the others, the male by its turquoise-blue spot on the head, and by the under 

 wing-coverts being yellow in both sexes. 



The bill in Coereba is longer than in any other genus of this family ; it is slender and 

 gradually arched, the cutting-edge of the maxilla being furnished with an indentation 

 near its extremity. The tail is short and nearly square at the end, and the tarsi and 

 toes moderately strong.
