Distribution. — Nothing is known of the range of this species, except 

 that the type was taken in the mountains of interior Guerrero. 



Description. — Crown dull grayish with a narrow black median line and 

 fine parallel lines on each side; back, rump and tail, with exposed part of 

 closed wings, gray like the crown and finely maculate with darker; back 

 and rump marked with narrow, dark shaft-lines ; scapulars marked with 

 small, roughly triangular black spots bordered Avith bufty ; gra^- of tail 

 indistinctly and irregularly barred with darker, and feathers tipped nar- 

 rowly with huffy ; chin, throat and sides of head grizzled gray, darker 

 than crown; neck encircled by a golden buffy collar, bordered along front 

 below by a narrow whitish band ; breast nearly' as dark as throat ; abdo- 

 men, flanks and lower tail-coverts pale buffy barred with gray and brown, 

 the light color predominating. The type and only known specimen is an 

 adult female. 



Size. — Wing 153, tail 116, culnien iS, tarsus 16. 



This form is readily distinguishable from any other known 

 Mexican species of the genus by its generally lighter or grayer 

 color and by the conspicuous, pale rufous or golden-buffy collar 

 which completely encircles the neck. 



Delattria pringlei, new species. PRiNGf.E's Hummkr. 



Type, No. 155219, U. S. Nat. Museum, Dept. Agric. coll., $ , from 15 

 miles west of Oaxaca City, Oaxaca, Mexico, September 14, 1S94. Col- 

 lected by E. W. Nelson and E. A. Goldman (Orig. No. 228S). 



Distribution. — -Mountains of central-western Oaxaca and thence into 

 Guerrero. 



Description. — Similar to Itoirici ^wd. inargarcthci; in general coloration, 

 but differing in the color of the throat patch, which is royal purple. 

 Using Ridgway's color nomenclature, the three species named above mav 

 be distinguished by the following colors of the throat patch. 



D. kenrici, phlox purple. 



D. margarethcE, violet. 



D. pringlei, royal purple. 



We obtained specimens of D. henrici at Mt. Zempoaltepec in 

 eastern Oaxaca. From central Oaxaca to central Guerrero D. 

 pringlei was found, and in the interior of the latter State D. mar- 

 garethce. was taken. Thus it appears that the three species occupy 

 contiguous areas. This species is dedicated to the field botanist, 

 Mr. C. G. Pringle. whose work in Mexico is so well known.
