1862.] DR. P. L,SCLATER ON SOME BIRDS FROM MEXICO. 19 
M. Sallé assures me that they are correctly marked. It is there- 
fore still possible that this species may be distinct from P. cerulea. 
4, DenpR@CA 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. Sallé 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 female 
of D. townsendii. I have, however, no doubt of the species being 
really distinct from both D. townsendii and D. maculata. 
5. DenpRa@ca MACULOSA (Gm.). 
A bird in winter plumage, obtained in February at Cosamaloapam. 
6. OpororNIs FORMOSA (Wils.). 
Playa Vicente. 
7. HELMINTHOPHAGA CELATA (Say). 
Example of both sexes from La Parada. 
8. Vireo HuTTONI, Cassin, Proc. Acad. Philad. 1851, p. 150, et 
1852, pl. 1. fig. 1; Baird, B. N. Am. p. 339. 
Example of both sexes of this Vireo, which I have not previously 
seen in Mexican collections from Cosamaloapam. 
9. VIREOLANIUS MELITOPHRYS, Bp. Consp. p. 330. 
One specimen of this beautiful but apparently scarce Mexican bird 
is in the collection obtained at Capulalpam. 
10. PyranGa LuDovICcIANA (Wils.). 
One example from La Parada. 
11. Emprponax oxnscurus, Baird, B. N. Am. p. 200. 
La Parada. M. Boucard has obtained specimens of a bird of this 
perplexing group, which I refer to Empidonax 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 VER#-PACIS, Sclat. et Salv. P. Z. S. 1860, 
p- 300. 
Playa Vicente. A Guatemalan species, new to the Fauna of 
Mexico.
