ON SOME NEW SPECIES OF CALLISTE. 
Whole length, 4.6; wings, 2.23. 
Inhabits Cayenne. 
I believe the bird figured Pl. Enl. 301, fig. 1, and which has 
hitherto been confounded with the true C. punctata (Linn.), to be 
of this species, of which I have two specimens, bought at a London 
dealer’s, There is a similar one at the British Museum, and I have 
also seen one other. 1 believe them all to be in a somewhat imma- 
ture state, from the general appearance of their plumage. I should 
suppose that the adult bird would show more yellow beneath. 
The present bird may be readily distinguished from the three 
affine species, by the comparative absence of spots, the leaden-blue 
of the back, wings, and tail, and the smaller size of the beak. It 
is the smallest of the four species here described.

Fe Pes wo to Mr. Edward Wilson for the loan of this bird, 
With othe Verreaux of Paris received from the Rio Negro along 
allied vo new and rare species of the same genus. It is closely 
co el the following species, C. chrysophrys, Sclater, but the 
we ae beneath is bright yellow instead of white, and the black 
aha aiken less conspicuous. The colour which lines the wing
