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 Roraima Mountains, some 5000 or 
6000 feet above it.

There are only four really recognizable species of Cereba, so far as we can see, 
though several others have been indicated, chiefly by Dr. Cabanis. Of these four, 
C. cyanea and C. cerulea 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. cerulea. The fourth species, C. nitida, is an inhabitant of the upper valley 
of the Amazons, and Colombia probably on the eastern slopes of the Andes. 
The species of Cereba 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 Cereba 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.
