Differs from /. viridis in its grej'ish upper surface and longer 

 tail. In winter plumage also it appears to be olive-brown, and not 

 so green as /. viridis. At the same time I have seen some spe- 

 cimeus which are so difficult to determine, that I have not been 

 able to satisfy myself that the two races are fully distinct. I have 

 therefore contented myself with separating the synonj^my, as given 

 by the American writers, and prefer to wait for further evidence on 

 the question. Tail about 3" 5 inches.
