genus, in considerable plenty. To all appearance it was the same spe- 

 cies as that found in the East, but as no specimens were obtained we 

 cannot be positive that the individuals in question were not P. plumhea. 

 They were certainly not P. melaneura [caZi/brwtca], which would have been 

 recognized by its black crown." The most northern range on the Pacific 

 coast is fixed at 42° by Dr. Coues, while on the Atlantic seaboard the 

 Connecticut Valley seems to be the terminus of their eastern migration. 

 Although not actually reported from Xevada, excepting the instance of 

 the Colorado Valley — which is not positively definite as to exact loca- 

 tion — the species is undoubtedly to be found there, as future investiga- 

 tions may show. 



Polioptila plumhea Baird. — Plumbeous Gnatcatcher. 



Dr. Cooper gives this as a winter resident about Fort Mojave, in small 

 numbers, where he procured one in February. 



Polioptila californica Lawr. — Black-tailed Gnatcatcher. 



This species is only recorded from Fort Mojave, by Dr. Cooper, where 

 he found it rather common during the whole winter. Mr. Gruber found 

 it as far north as 39°, on the Sierra IsTevada, and it is probable that its 

 easternmost rauge in that latitude may bring it down to the foot-hills 

 into Kevada. 



Begulus calendula (Linn.) Licht. — Ruby-crowned Kinglet. 



Abundant during the fall months among the pines on the eastern slope 

 of the Sierras, near Carson City. — {Henshaiv.) At this place it was found 

 most numerous in April. — (Bidgway.) The species was also observed at 

 West Humboldt Mountains and in the Truckee Bottom, near Pyramid 

 Lake, by the latter authority. 



Regulus satrapa Licht. — Golden-crowned Kinglet. 



One of the most diminutive of the birds of Nevada, excepting the 

 Humming Birds, and appears to be rare. Mr. Eidgway observed " a 

 few individuals in the canons of the West Humboldt Mountains, among 

 the thick bushes along the streams." 



TARIDM. 



Loplioplianes inornatus (Gamb.) Cass. — Plain Titmouse. 



This species has thus far been reported only from the eastern foot-hills 

 of the Sierras, where Mr. Henshaw found it " a resident, but not numer- 

 ous." Mr. Eidgway also notes its occurrence near the same locality as 

 frequenting the cedar and piiion forests. 



Parus montanus Gamb. — Mountain Chickadee. 



Mr. Eidgway states that " the distribution of this species seems to be 

 governed entirely by that of the coniferous woods j consequently, we
