VIREO HUTTONI, Gas sin. 



Uiittoii's Flycatcher* 

 Hreo hutlotu. Cassis, Pr. A. N. So. Phila. V, Feb. 1851, 150.— lu. VI, pi. i, f. 1. 



Sp. Cii. — Fourth, fiflli, and sixth quills about equal and longest ; third and seventh equal, and .10 of an inch shorter ; second 

 quill not longer than secondaries; spurious primary largo, broad, about half the second. Above olive green, becoming 

 considerably darker towards the bill and on sides of head. Beneath dirty greenish white, tinged with greenish yellow 

 posteriorly. A paler ring round the eye. Two broad bands across the wing coverts and edges of inner tertiarics, with greater 

 portion of outer web of the outer tail feather greenish or oliraceous white. Length about 4.73 inches ; wing, 2.33. 



Bab. — South California, across by valley of Gila, to northeastern Mexico. 



The yellowish riug round the eye is very narrow. The space between the upper edge of the 

 eye and the bill is yellowish, but not well defined. The rest of the sides of head and neck are 

 dark olivaceous, like the back. There is no white whatever in the under parts or elsewhere, the 

 lightest tints beneath being yellowish, with a brownish tinge. The sides of the body are 

 olivaceous yellowish. 



This species differs from V. gilvus in its large first primary, the whitish bands and edgings of 

 the wings and tail, and in the more olivaceous colors generally. It is of rather smaller size. 

 It is about the same size as V. noveboracensis, but has a much more slender bill, which is horn 

 color instead of blue black ; it lacks the vivid yellow on the forehead and in front of the eye ; 

 the head is darker ; the outer tail feather paler ou its outer edge. It lacks the pure white of 

 the throat and the vivid contrast in color between the sulphur yellow of the sides and the 

 whitish of the middle of the body. Both species have concealed whitish on the rump. It is 

 larger than V. belli, although the bill is the same size ; it has the sides of the head and neck 

 much darker ; there is more whitish on the wing and outer tail feather ; the inferior colors are 

 much browner, with less of the vivid sulphur yellow. 



The differences between the present species and the closely allied V. cassinii will be pointed 

 out in the description of the latter species.
