only very slightly fulvous, without any well definca edging. This 

 is also the case with Bome Costa Kiea skins. 



Mexican specimens seem to have shorter bills than Guatemalan. 

 Ill all there is a decided bare space beJiind the eye, less marked, 

 however, especially around the eye, than in T. (jijinnujihllialmutf. 

 The latter species is otherwise somewhat similar, dillering mainly in 

 the absence of the cinnamon tinge to the under parts of the body. 



Male and female specintens from I'anama, in Mr. Lawrence's col- 

 lection, exhibit both extremes of coloration of the quills as referred 

 to above. 



I do not consider the evidence l)efore me favorable to the scpara- 

 ration of T. ceesius from the original grayi ; and therefore, for the 

 present, prefer to unite the two species. Planesticus luriduH, Bon. 

 Notes Orn. Delattre, 28, New Qrenada, probably, as suggested by 

 Sclater, belongs here also. 



It is difficult to say to which of the Mexican Planestici the Tardus 

 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 1\ leucauvhvn better 

 than grayi, to which it has generally been referred, but is too far 

 from the truth to admit of being identified with either.
