Pipilo chlorosoma, Baird. 50,225 ♂, Oaxaca. Similar to P. macronyx in color, but without any trace of white markings on the wings. Outer tail-feathers with an obscurely defined greenish-white patch about an inch long, at the end of inner web; similar, but successively smaller patches on the second and third feathers, all whiter on upper than lower surface. Fifth quill longest; first shorter than ninth.
Dimensions (prepared specimen): Total length, 8.20; wing, 3.75; tail, 4.80. Bill: Length from forehead, .73; from nostril, .43. Legs: Tarsus, 1.24; middle toe and claw, 1.10; claw alone, .36; hind toe and claw, .85; claw alone, .50. No. 60,050, Mexico, is similar, in all essential respects.
From the analogies of the black Pipilos, it is reasonable to consider these two birds as distinct species, or at least varieties, especially as the specimen before us of that with unspotted wings is marked male. The general appearance is otherwise much the same, the unspotted bird rather smaller, and without the dusky interscapular markings described in macronyx. Should No. 50,225 represent a distinct species, it may be called P. chlorosoma, and distinguished as above. (60,050, Mexico, Boucard.)
