nigrifrons; wings and tail blackish, edged with dull grayish; breast black, 

 flanks and abdomen, back of yellow pectoral spots, white mixed with 

 blackish; under tail-coverts white. 



The type is the only specimen obtained of this beautiful bird. 

 It was shot in an old potato field in the forest a little below 10,000 

 feet. Others were seen and the bird did not appear to be un- 

 common, but not appreciating its distinctness from auduhoni at 

 the time, I failed to secure additional specimens. 



Its nearest relative is Dendroica nigrifrons Brewster, from 

 which, however, it presents various striking differences. It has 

 yellow markings of the same shade and distribution as in nigrifrons 

 and auduhoni. 



This species is dedicated to my assistant, Mr. E. A. Goldman, 

 whose services have aided so largely in the formation of the 

 collection upon which the present paper is based.

Disiribution. — From" Yajalon, Chiapas, to San Andres Tuxtia, Vera 

 Cruz. 



Description of type. — Crown rufous, darker than in ruftfrons, with a 

 faintly marked median line of lighter strongest on the forehead; super- 

 ciliary stripe white; a white spot just back of and below the ear-coverts 

 on the side of the neck, forming the termination of a grizzled whitish 

 band which extends back along the side of the head, from the chin, and 

 reaches up nearly to the lower eyelid ; lores, a narrow line around each side 

 of the eye, and a postocular spot black ; cervical collar on the sides and 

 back of the neck, just back of the rufous crown, olive-shaded, ashy-gray; 

 remainder of upper parts including exposed borders of the wing and tail- 

 feathers dark olive green ; throat, breast and middle of belly bright 

 yellow, but less intense and slightly washed with buffy on the latter; the 

 sides of the breast and flanks olive green, shaded with buffy posteriorly : 

 the under tail-coverts are huffy. Its size is about the same as riififrons. 



This species has the head markings much as in ruffrons, with 

 the yellow ventral surface of delattrii. Specimens from San 

 Andres Tuxtia. Vera Cruz, are not quite so richly yellow below 

 as the type.
