BEVIEW OP AMERICAN BIRDS. 



[part I. 



The essential characters of this genus are to be found in the con- 

 siderably rounded tail, which somewhat exceeds the wings, and in 

 the very short, much rounded wings and considerable amount of 

 graduation of the primaries — the sixth being longest, the second 

 shorter than the secondaries, and the third barely longer than the 

 tenth. But one species is known, the coloration of which is entirely 

 peculiar in the family, 



IVeochloe Tirevipennis. 



Neochloe hrevipennis, Sclater, P. Z. S. 1857, 213 (Orizaba, Botteri). 

 Hab. Orizaba. 



(No. 38,163.) Wing much graduated; the 6th longest; first quill more 

 than half 2d ; second shorter than secondaries. Tail longer than wings, 

 somewhat graduated. 



General color dark ashy plumbeous ; the entire top of head and nape sap 

 green ; the outer surface of wings bright greenish-yellow, edges of tail feathers 

 and upper tail coverts similar, but duller ; edge of bend of wing bright yel- 

 low. Chin and median region of abdomen, including crissum, white, as are 

 the lining of wing and inner edges of quills. Concealed portion of wing and 

 tail feathers above, as well as their under surfaces, almost black, especially 

 the quills. Bill and feet plumbeous black. 



(No. 38,163.) Total length, 4.40; wing, 2.25; tail, 2,40; difference of 

 feathers, .24; difference of 10th and longest quills, .34; exposed portion of 

 1st primary, .67, of 2d, 1.26, of 3d, 1.56, of longest (6th) (measured from ex- 

 posed base of 1st primary), 1.80; length of bill from forehead, .50, from 

 nostril, .25, along gape, .56 ; tarsus, .75 ; middle toe and claw, .53, claw alone, 

 .15 ; hind toe and claw, .44, claw alone, .23. 



The outer edges only of the quills are green, so that the inner 

 secondaries exhibit a good deal of black. The outer two primaries 

 are edged with gray, not green, and on the other primaries the latter 

 color changes to gray towards the end. The specimen described is 

 the second known, the type, also collected by M. Botteri, being in 

 the British Museum. 



HYLOPHILUS, Temm. 

 " Hijlophilus, Temm. PL Col. 173, fig. 2. (Type H. pacilotis, Temm.") 



Similar to Vireo in general appearance, but shorter and stouter. Wing 

 short, rounded, about equal to the tail, which is narrow and rounded, the
