TURDUS. Psi 
only very slightly fulvous, without any well defined edging. ‘This 
is also the ease with some Costa Rica skins. 
Mexican specimens seem to have shorter bills than Guatemalan. 
In all there is a decided bare space behind the eye, less marked, 
however, especially around the eye, than in Z. gymnophthalmus. 
The latter species is otherwise somewhat similar, differing mainly in 
the absence of the cinnamon tinge to the under parts of the body. 
Male and female specimens from Panama, in Mr. Lawrence’s col- 
lection, exhibit both extremes of coloration of the quills as referred 
to above. 
I do not consider the evidence before me favorable to the separa- 
ration of 7. cesius from the original grayi; and therefore, for the 
present, prefer to unite the two species. Planesticus luridus, Bon. 
Notes Orn. Delattre, 28, New Grenada, probably, as suggested by 
Selater, belongs here also. 
It is difficult to say to which of the Mexican Planestici the Turdus 
tristis of Swainson belongs. His description of “olive brown, be- 
neath whitish ; chin with black spots; under wing coverts pale fer- 
ruginous; bill and legs brown,” really suits 7. leucauchen better 
than grayi, to which it has generally been referred, but is too far 
from the truth to admit of being identified with either.
