much lighter colour of the upper parts, the mantle being lighter, 

 not darker than the No. 7 grey of my ' Nomenclature of Colours.' 

 The upper tail-coverts and tail still paler, while the entire nape and 

 pileus are white, the former marked with crescentic bars, and the 

 latter more sparsely with cordate and sagittate spots of slate-colour ; 

 the white edgings of the greater wing-coverts and secondaries are 

 much broader, and the inner web of the lateral tail-feathers is 

 wholly pure white, the outer web also white, with grey bars. 

 Notwithstanding the much paler coloration of the upper parts, 

 however, the soft brownish grey of the under parts is quite as dark 

 in CE. fisheri as in CE. gulans, and occupies just about the same 

 area; but the well-defined bars on the flanks seen in the latter 

 seem to be quite absent in (E.fisherV *

" Inner webs of primaries abruptly white for at least the inner 

 half ; wing more than 9 inches. Above, including the whole top of 

 the head, dark bluish grey, the feathers of the back and scapulars 

 broadly bordered terminally with ashy white, the middle and 

 greater wing-coverts similarly marked ; chin, throat, chest, centre 

 of breast, and under tail-coverts plain white ; rest of the lower 

 parts vermiculated and irregularly barred with slaty-grey or plum 

 beous, this becoming uniform and somewhat darker on the belly ; 

 tail chiefly plain light brownish-grey. Wing 9-88, tail 3-95, culmen 

 1-03, depth of bill at base -46, tarsus 1-37, middle toe with claw 

 1-7." {Ridgway, Man. N. Am. Birds, p. 68.) 



Hah Unknown ; the type was taken in the interior of the State 

 of New York. 



The single type-specimen of this species, which is now in Mr. 

 WiUiam Brewster's collection, is, he tells me, in poor condition 

 and mounted in a case, and thus unfit to be sent to England for 

 purposes of comparison. 



This species seems evidently closely allied to CE. gularis and 

 (E. JisJieri, and as Mr. Brewster is the only person who has had 

 the three types under his eye at one time, his original full de- 

 scription and comparison give the most authentic account of the 

 relationship of the three forms.
