Inhabits Cayenne and Demerara. 
This bird, of which I give a description for the purpose of com- 
parison with the following three, newly described, was first noticed 
by Brisson as “ Tangara viridis indica maculata.” Linnas; 
quoting this description, and associating with it Edwards’ figure of 
the “ Parus maculatus,” formed hence his Tanagra punctala. 
Buffon’s figure, Pl. Enl. 133, fig. 1, also represents this spect’: 
and Desmarest has figured both sexes in his Histoire Naturelle des 
Tangaras. It appears to be a common bird in Cayenne and Dem’ 
rara, from which country I have seén many specimens.
