364 SHRIEKING BIRDS — STRISORES. 



Mr. Lord found this species numerous near tlie northwest boundary line, 

 east of the Cascade Mountains in May, arriving with <S'. rufus, and fre- 

 quenting the Ribcs flowers also. During the summer he observed them 

 chiefly about rocky hillsides at great altitudes, frequently above the line 

 of perpetual snow, and discovered the nest, usually on the liranch of a 

 young pine, artfully concealed among the leaves at the very end so as to be 

 rocked by the lireeze. 



I probalily saw the same species in August, 1853, on the summit of the 

 Cascade Mountains, liut mistook them in their moulting plumage fi-ir tlie 

 yoimg of »S'. rufus. (Cooj^er.) 



Genus HELIOPiEDICA, Gould. 



ndiopadka, Gould, Jlon. Trocbil. II. ; Intiod. Troclul. 18G1. 60. (Type, Tmcliilus melaiio- 



tis, SWAIN.SON.) 



Gen. Char. Bill longer than head, depressed ; broad at its exposed base ; the frontal 

 feathers not advancing forward beyond the beginning of the nostrils, nor so far as those 

 of the ehin. Hind toe shorter than the lateral ; tar.si feathered. Outer primary not at- 



_ f/ 



tenuated. Tail nearly even, slightly roundeil and emarginate, the feathers broad, the 

 webs nearly even. Metallic feathers of throat nut elongated. Female quite similar in 

 form. 



TIlis genus is quite peculiar among those of North America, in the ex- 

 posure of the liase of Ijill, which is entirely bare between the lengthened 

 nostrils, instead of co\-ered by the frontal feathers. Tliis makes the Tiill 

 appear very broad, although it really is more so tlian in our other genera. 

 The feathers on tlie chin extend considerably beyond those of the forehead, 

 instead of to about the same line. The tail and its feathers are much 

 broader than in the other genera. 



Of Hcluqxndica there are two species, both with green throats and white 

 stripe in the black of the side of the head ; the top of head blue ; they differ, 

 however, in decided characters. (Baird.)
