The T. episcopus of Linnaeus depends1 upon Brisson’s ‘ Episcopus
avis,’ and from Brisson’s description and locality I think there can
_be little doubt that thé present species with white shoulders and
narrow edgings to the greater coverts was intended.1 ■ ^
The only bird likely to be confounded with it is the néxtfollowing
species T. coelestis, which has a regular white bar across the wings
formed by the pure white terminations of the greater coverts.

These blue ‘ Bishop ’ Tanagers are very puzzling, and I confess I
am as yet quite unable to arrange them satisfactorily. After separating
the true * episcopus ’ and * coelestis ’ (which are clearly distinct)
and the large South Brazilian * cyanoptera ’ (which may also
he -recognized without much difficulty), there remain four or five
birds -with different names attached to them, varying a good deal in
the amount of blue on the wings, but not otherwise presenting very
appreciable’ differences. At present I am inclined to refer them to
two, speciesr—a South American bird with the lesser wing-coverts of
a more or less violet tint—and a Central American and Mexican
species with these parts deep blue—like the South Brazilian T. cyanoptera'.
The former bird is common in collections from Bogota
and Trinidad, and seems to range so far south as the Amazon at
Para. The latter extends from the north coast of New Grenada
through Central America as far north as the province of Vera Cruz,
whence specimens have lately been brought by M. Sail A
