This Manakin is a beautiful Mexican representative of P. rubri- 

 capilla and P. chloromeros. From the former it may be distin- 

 guished by its yellow thighs, from the latter by its yellow chin and 

 under wing-coverts.

Schistacea unicolor, subtus pallidior, ventre albicantiore : remigibus

 albidiore : cauda nigra; rectricibus duabus mediis schistaceis^ 

 harum duarum utrinque extimarum parte apicali pallidior e et api- 

 cibus ipsis cum margine interna apicem versus albis : rostro et 

 pedibus nigris. 

 Long, tota 7*5, alse 3*8, caudse 3*4. 

 Salle, no. 150. Cordova, <? et ? similes. 



This bird is certainly quite distinct from Lafresnaye*s M. obscura, 

 of which I possess examples from Guatimala. Judging from^udu- 

 bon's plate and description it likewise would seem diiferent from P. 

 townshendi, which has been united to Lafresnaye's species, I believe 

 quite erroneously, by Prince Bonaparte. 



My impression is that the Berhn Museum specimens, marked 

 "Hypothymis ccesia,** are identical with the present bird ; but as I 

 have no means of verifying that fact, and the name is merely in MS., 

 I think it safer to give it a new appellation. 



Lafresnaye's M. obscurus (R. Z. 1839, p. 99), of which I have 

 examples procured near the city of Guatimala by Signor Constancia, 

 may be recognized at once from the present species by its brown 

 back and rufous wing-edgings.
