P. 75. Curve-billed Thrush. Specimens lately received indicate that the Arizona bird 
constitutes a variety of H. curvirostris: the following is a better description than that given 
in the text. — Var. palmeri Ripaw. Ms. Above, grayish-brown, nearly uniform; wing 
coverts and quills with slight whitish edging, the edge of the wing itself white; tail feathers 
with slight whitish tips; below, a paler shade of the color of the upper parts, the throat 
quite whitish, the crissum slightly rufescent, the breast and belly with obscure dark gray 
spots on the grayish-white ground; no obvious maxillary streaks, but vague speckling on 
the cheeks; bill black; feet blackish-brown; bill 1}; wing 44; tail 5; tarsus 14; middle toe 
and claw 14. (Described from 61589, Mus. Smiths. Inst., Tucson, Arizona, Bendire.)

of V. solitarius, as intimated in the text. 
P. 129. For Genus Curvirostra Scopoli read Genus Loxta Linneus. The Red Crossbill 
may be considered as var. americana of the European Loxia curvirostra.
