In the < Annals of the Lyceum of Nat. Hist, of N. York/ as 
above cited, I pointed out some differences between the birds 
received from Panama and C. flavigastra from Cayenne. Others, 
since received, showing these differences to be constant, I am 
induced to consider them to be distinct species. 
The specimens from Panama are smaller, the upper plumage 
is of a rather deeper brown, except the rump, which is greyish 
white, the yellow of the abdomen is rather paler, and the under 
tail-coverts whiter. 
Male. Length about 5 inches; wing ; tail 2J. 
Female. Wing 3f inches; tail 2. 
The wings of two specimens of Cotyle ruficollis sive flaviga - 
sir a *, from Cayenne, measured 4f inches ; the sexes of these are 
not known.

* [This bird agrees with the specimens from Ecuador which I have noticed, 
in my list of Fraser’s collection, P. Z. S. 1860, p. 292, as showing differences 
from C. ruficollis .—P.L.S.]
