. Review of American birds in the Museum of the Smithsonian Institution: pt. 1 . Birds. vmEO. 351. Vireo noveborcuiensis. (PennBylvanla.) The species of Vireo are most easily tabulated by color, and in the following synopsis no regard is paid to external form, bat species of Vireo and Vireonella are mixed together. It will, however, be remembered (page 326) that V. noveboracensis, atricapiUus-, car- mioli, huttoni, belli, vicinior, a, rd pusillus fall under the head of Vireo proper, with their longer, more pointed wings, and (except in vicinior) smaller outer primary—belli, vicinior, &ndpusillus differing, however, from the others in longer tarsi, and longer and more graduated tail, with narrower, more pointed feathers. Under Vireonella are to be ranged V. modestus, latimeri, pallens, ochraceus, crassirostris, gund- lachi, and hypochryseus, each of which has a peculiar form. V. modestus in its very small bill approaches closely to huttoni, most of the other species having rather larger bills than the average. Common CaABACi>EBs.—All the species olivaceous above, or ashy; beneath whitish, or olivaceous-yellow. Wings with light bands, except in latimeri and hypochryseus; tail without spots.
