Plumbeous Vireo. Leaden-gray, rather brighter and more ashy on the 

 crown, but without marked contrast, faintly glossed with olive on rump ; 

 a conspicuous white line from nostril to and around eye, and below this a 

 dusky loral stripe ; below, pure white, sides of neck aud breast shaded with 



color of the back, tlanks, axillars 

 and crissum with a mere trace of 

 olivaceous, or none; wing and tail 

 dusky, with conspicuous pure white 

 edgings and cross-bars. Size of 

 the last or rather larger ; bill nearly

spurious quill about f , one-third as long as the second quill. Central Plains 

 to the Pacific, U. S., and especially Southern Rocky Mountains, where it is 

 abundant. A large stout species, a near ally of soUlarius, but nearly all 

 the olivaceous of tiiat species replaced by plumbeous, and the yellowish by 

 white, so that it is a very different looking bird. It may prove onl^' a 

 variety, but I have seen no intermediate specimens, and cannot reconcile 

 the obvious discrepancies, upon this supposition. Coues, Pr. Ac. Phila.,

 r/i Gray Vireo. With the general appearance of a small faded specimen of 

 jplumbeus : leaden-gray, fiuntly olivaceous on the rump, below white, with 

 hardly a trace of yellowish on the sides ; wings and tail hardly edged with 

 white ; no markings about head except a whitish eye-ring. 5| ; extent 85 ; 

 wing and tail, each, 2J ; tarsus nearly % ; middle toe and claw hardly over J ; 

 tip of inner claw failing short of base of middle claw ; tail decidedly 

 rounded ; spurious ciuill f , half as long as the second primary, which latter 

 is not longer than the eighth. Arizona. If these peculiar proportions of the 

 single known specimen are constant, the species is distinct from any other. 

 It is our plainest colored species, resembling plumbeus, but apparently 

 more closely allied to the smaller rounder-winged species like novebora- 

 censis and especially pusillus ; the toes are almost abnormally short, and 

 the tail as long as 

 the wing. Coues,
