1862.] DR. p. L, SCLA.TER ON SOME BIRDS FROM MEXICO. 19 



M. Salle assures me that they are correctly marked. It is there- 

 fore still possible that this species may be distinct from P. ccerulea. 



4. Dendr(eca chrysoparia, Sclat. et Salv. P. Z. S. 1860, p. 298. 

 This beautiful Wood-warbler was originally discovered by Mr. 



Salvin in Guatemala. See 'Ibis,' 1860, p. 273. M. Salle now sends 

 me three examples from La Parada; and I have found a female already 

 in my own collection, which I had previously mistaken for the femafe 

 of D. townsendii. I have, however, no doubt of the species being 

 really distinct from both D. townsendii and D. maculata. 



5. DeNDRCECA MACULOSA (Gm.), 



A bird in winter plumage, obtained in February at Cosamaloapam. 



6. Oporornis FORMOSA (Wils.). 

 Play a Vicente. 



7. Helminthophaga celata (Say). 

 Example of both sexes from La Parada. 



8. Vireo huttoni, Cassin, Proc. Acad. Philad. 1851, p. 150, et 

 1852, pi. I. fig. 1; Baird, B. N. Am. p. .339. 



Example of both sexes of this Vireo, which I have not previousl3'^ 

 seen in Mexican collections from Cosamaloapam. 



9. VlREOLANItfS MELITOPHRYS, Bp. Consp. p. 330. 



One specimen of this beautiful but apparently scarce Mexican bird 

 is in the collection obtained at Capulalpam. 



10. Pyranga ludoviciana ("Wils.). 

 One example from La Parada. 



11. Empidonax obscurus, Baird, B. N. Am. p. 200. 



La Parada. M. Boucard has obtained specimens of a bird of this 

 perplexing group, which I refer to Empido^iax obscurus, as distin- 

 guished by Prof. Baird, as also of another nearly allied but appa- 

 rently distinct species, to which at present I am unable to find any 

 reference. 



12. Tyrannus crassirostris, Sw. 



Oaxaca. I believe this Tyrant is exclusively a western species ; at 

 least I have never seen it in any collections from the eastern parts of 

 Mexico. 



13. Heteropelma vERiE-PACis, Sclat. et Salv. P. Z. S. 1860, 

 p. 300. 



Playa Vicente. A Guatemalan species, new to the Fauna of 

 Mexico.
