Central America. 



257. P. car-pa'-lls. Gr. Kapiros, fruit, berry, grain; also, the wrist; Latinized as carpus. The 



derivation supposed to be Kaptyco, I gather, as fruit ; Lat. carpo, I take, seize. The quasi- 

 Latin carpus is only used as signifying the wrist ; the adjective carpalis is an arbitrary 

 form, denoting of or pertaining to the wrist; carpus and carpal are common terms in 

 anatomy. The allusion is to the bright color on the carpal-joint of the bird's wing. 



258. Am-phl-spi'-za bi-lin-g-a'-ta. Gr. d,u</>t, on both sides, and a-rrifr, a finch ; in allusion to 



the close relation of the genus to those about it. See Melospfza, No. 242. Lat. bilineata, 

 two-lined; Ills, twice, and lineatus, striped; linea, a line: see Linaria, No. 207.

260. A. b. ngv-a-den'-sis. To the Territory of Nevada. It were better written nivadensis,\n 



Latin, but is directly from the Spanish adjective ncvada, snowy, white as snow ; Lat. 

 nii-eus, snowy, from nix, genitive, niris, snow. The Territory was named for the snow- 

 capped peaks of its Sierras Nevadas. 



261. Jun'-co [pronounced yooncoj hi-g-ma'-lls. Lat. juncus, a reed or rush; cf. junr/o, I join, 



junctus, joined ; either, reeds growing densely together, or used as withes to bind with? 

 For hiemalis, see Anorthura, No. 76. 



262. J. h. ai'-kgn-i. To Charles E. Aiken, of Colorado, its discoverer. 



This and several other connecting forms of Junco (Nos. 264, 266, 267) are not in
