Cereba cyanea is found over nearly the whole of the continental portion of the 
Neotropical region, being an inhabitant of the low-lying country up to an elevation of 
about 3000 or 4000 feet. We once observed it at Duefias in Guatemala at a height 
of nearly 5000 feet ; but its occurrence so high must be considered exceptional. So 
far as our experience goes, it is not a bird of the open savannas, but resorts to the edges 
of the forests and second-growth woods, and may even be seen in the hedgerows of 
villages in such situations. It is absent from the West-Indian islands with the 
exception of Cuba, where, singularly enough, it occurs to the exclusion of all species 
of Certhiola, whose place it seems to take. This is the more remarkable, as the Antilles 
foster Certhiola to such an extent that nearly every island has its distinct race. 
In 1859 Mr. Sclater separated Mexican specimens of C. cyanea under the name of 
C. carneipes 12, at the same time doubting whether the minute differential characters 
to which he drew attention were really of specific value. The receipt of a large series 
of specimens from a wide unbroken range has convinced us that no such separation 
can be maintained; the bird, in fact, being unusually constant in its coloration, con- 
sidering the vast area over which it is spread. | 
In its habits C. cyanea is restless in search of insects, climbing over every twig and 
examining every leaf in its way. We never met with its nest or eggs.

This Central-American species seems fairly separable from C. cwrulea of the Southern 
continent ; not only does the colour of the male differ in being of a less dense purplish- 
blue, but the black of the throat extends further on to the breast. These differences 
are very apparent when Central-American and Guiana birds are compared. The range
