Eolliiwiiig is a (Icscription of an example of this species in the down; — Doiniij Voianj : Head and 



neck longitudinally striped with dusky and dull wliite, the dusky striiics widest {cxcc[it underneath the 



head), and about .six in luiniber ; the crown is divided 

 mc<lially liy a narrow .stripe of white, wldch, liow- 

 evcr, docs not extend anteriorly to the white of llie 

 forehead ; the dusky stripe, extending liaek from llie 

 lower eyelid, tenninates just behind the ears, but tliat 

 extending from above the eye is continued down the 

 side of the neck, there lieing between this and its fel- 

 low of the opposite si(U' three dusky stripes down tln' 

 back of the neck ; there is a broad but short rictal 

 streak, with tliree narrower streaks on the chin ; there 

 are also three dusky .streaks on the throat — one on 

 e.ich side, and (uie between. The plumage of the body 

 is dull grayish-fuliginous, lighter beneatli, where fading 

 into dull grayish white on the abdomen. (N'o. 57307, 

 Europe.) 



From the corresponding .stage of C. crintaliis, lids 

 may be distinguished most readily by the much darker 

 lower parts, the abdonu'U only being light colored, and 

 this dull grayish white, while in the young of C en's- 

 tidim the entire lower parts, except the .sides, are nearly 

 pure white. There are also some dill'ercnces in the 



markings of the head and neck, the most obvious of which consist in the absence of .streaks on the throat 



in t\ cristiUus.
