ham, Ariz.] quite rare as comi^ared with solitarius; but, near Camp Crit- 

 tenden, the last few days of August, quite a number were seen among 

 the deciduous trees. Their seeming preference for the deciduous trees 

 over the coniferous timber is the only j)oint wherein their habits seem 

 to differ from those of the Solitary Vireo." 



Lanivireo solitarius plumheus (Cones) All. — Plumbeous Vireo. 



This species, belonging more particularly to the Eocky Mountain 

 Region, was found by Mr. Eidgway on the eastern slope of the Euby 

 Mountains. According to Mr. Henshaw, it is common during summer 

 among the pines of the mountains. 



Vireo belli Aud. — Bell's Yireo. 



But a few years since Mr. Henshaw secured a single individual on 

 the Gila Eiver, Arizona, showing its occurrence in the Southwest. K 

 Dr. Cooper's notice at Fort Mojave is correct, the species is no doubt to 

 be looked upon in Nevada as an extremely rare visitor, although Dr. 

 Cooper's belli has long been supposed to be V. pusillus. 



LAOTID^. 



Lanius horealis Vieill. — Great Northern Shrike ; Butcher Bird. 



Noted by Mr. Eidgway at Carson City during February and March, 

 where it occurred in the sheltered ravines along the foot-hills of the 

 mountains. This species appeared at all times less common than ex- 

 cuMtorides. 



Lanius ludovicianus excubitorides (Sw.) Coues. — White-rumped Shrike. 

 Dr. Cooper found this bird common at Fort Mojave during the winter, 

 leaving for the timbered caiions and hills in spring. Over nearly the 

 whole of the area from Bull Eun Mountain southward as far as Bel- 

 mont and westward toward the Inyo Eange, California, we found this 

 species in the higher belts of timber. At Eureka, especially along the 

 western slope of Prospect Hill among the groves of Cercocarpus, thence 

 southward toward Hot Spring Caiion, along the densely-covered hills, 

 this bird was conspicuous, being frequently observed in its search for 

 food by suddenly darting from a dry projecting branch upon which it 

 had been patiently and silently watching. In the Valley of the Hum- 

 boldt, and as far north as Independence Creek, the cottonwood groves 

 seemed the favorite resort of this bird, a fact due, perhaps, more to the 

 general abundance of cottonwood trees to the exclusion of pines. 



AMPELIDJi}. 



Ampelis garrulus Linn. — Northern Wax-win^. 



The only report regarding this species is that by Dr. Cooper, who saw 

 it at Fort Mojave in January, 18G1, which is the first instance of its oc- 

 currence in the United States.
