158 New Birds from Yucatan. 



whitish towards their ends ; the secondaries have their outer webs of a 

 warmer brown than the primaries, and they are also edged with white as in 

 the primaries ; the inner webs of all the quills are clear cinnamon-red, the 

 primaries at their ends for one and a half inches are dark brown ; the under 

 wing-coverts are deep cinnamon-red ; bill black ; tarsi and toes clear flesh- 

 color — probably crimson in the living bird. * 



Length (skin), 10 inches ; wing, 5.75 ; tail, 4.25 ; bill from front, 0.70 ; 

 tarsus, 1. 



Habitat, Silam, Yucatan. Type in my collection. Collected 

 by George F. Gaumer, whose name I have conferred upon it. 

 Concerning it Mr. Gaumer writes as follows : "During one week 

 that I was at Silam, I found the doves to be quite rare ; ten were 

 taken, all of which were like the specimen sent you, i. e'., with 

 the white front and brilliant reflections on the neck. The spe- 

 cimens from the interior (E. fulviventris) are larger and darker. 

 The song of the coast bird is more prolonged and of tener repeated 

 than the other." 



Remarks. — This species, in distribution of colors, most resem- 

 bles E. Jamaicensis, but differs from it in being smaller in all 

 its dimensions, except that the bill is perceptibly larger and 

 stronger. The upper plumage is of a much lighter olive, being 

 brownish in Jamaicencis ; the middle tail-feathers are darker 

 and narrower, with their shafts dark brown, these in the other 

 being of a light reddish-brown ; in the new species the cinnamon- 

 color of the inner webs of the primaries reaches up to the shafts, 

 in Jamaicensis it is separated from them by a dusky space. I 

 have before me four specimens of the latter, with which to make 

 comparison. 



From E. albifrons, it is readily distinguished by its having the 

 front largely pure white, which in albifrons is bluish-white and 

 the color more restricted ; also by the more brilliant reflections 

 on the hind neck and by its white throat ; the most marked dif- 

 ference is, that the inner webs of the quills are entirely of a cin- 

 namon-red, whereas in albifrons they have only a very pale edging 

 of that color. 



Last spring Mr. Gaumer went to Yucatan on his second expe- 

 dition to that country, to collect specimens in the different 

 branches of natural history. Lately I received from him two 

 small collections of birds, which contained the specimens above 

 described. 



* Chin and throat white; sides of the head, the breast and sides, pale 

 vinaceous; abdomen and under tail coverts white.
