Mexico and Ouateniala ? Not noted from West Indies. I aiu still much perplexed in reference to the distinctness of tho /. velasquezii from /. virens. All the Chats I 'lave seen from lof-alities south of the United States (four in the Smithsonian collection) agree in having the bill lighter colored, the upper nian- (liblo brown with lighter lower edge, the lower nearly whitish. All have the sides and crissum tinged with brown. The size is rather less than in viridis, the proportions about the same; the tail if any- IhinfT shorter, not longer. In two specimens the bill is shorter, higher, and the culmen more curved than in any virens I have seen; ill one it about the same, and in another (13,601) it is longer and more slender. The white maxillary patch is rather restricted. Ill no adult male specimens from tho United States do I find the bill other than intense black, and the crissum pure white. Tho flunks arc a little brownish, but less so than in Mexican skins. A female from Carlisle, Pa., however (2,312; May), has the crissum and flanks precisely as in southern specimens ; the bill, also, is nearly as light colored. /. longicauda has the tail much longer, and the upper parts much grayer. The mandibular white extends farther back, as does the white at the posterior corner of the eye. Young birds from Capo St. Lucas differ from adults in the light-colored bill, and brownish wash on the flanks and crissum ; but the back, instead of being pure olive green, has a brownish faded appearance. Cabanis (Jonrnal, 1860, 403), in summarily uniting all described Icteria into one species, entirely overlooks the great difference in the length of the tail of eastern and western specimens. Ideria auricollis, of Licht, doubtless refers to /. velasquezii. Specimens of this species are in the S
