that this is the true Zonotrichia botterii of ScL. P. Z. S. 1857, p. 214. Dr. Sharpe indicates 

 by his synonymy that he considers this to be also P. arizoncB of Kidgw. Pr. U. S. Nat. Miis. 

 i, Aug. 1878, p. 127. It would appear that Mr. Ridgway has at different times confounded 

 the two supposed species under the one name of P. arizon(e. This does not invalidate his 

 original P. cestivalis arizoncB of 1873, as above cited, but brings in question his P. arizonce of 

 1878, which the A. 0. U. Committee cites as authority for the name of the foregoing species. 

 P. cas'sini. (To John Cassin.) Cassin's Summer Finch. Belonging to the cestivalis 

 group, with yellow edge of wing, and most resembling arizonce; but perfectly distinct. A 

 peculiar character of marking raises groundless suspicit)n of immaturity. Adult ^ 9 : Entire 

 upper parts, from bill to tail, alike in pattern of coloration — a peculiarly intimate variegation 

 of ashy-gray, rufous-brown and blackish — the ruddy color occupying most of the feathers, 

 which have a blackish central field and gray edging ; the blackish area on each feather, espe- 

 cially of back, rump, and upper tail-coverts, where it is most conspicuous, being hammer- 

 headed, or widened toward end of the feather. Pattern of markings smallest on cervix. No 

 special head-markings, but a tendency toward a lateral browner band on side of crown, and 

 browner postocular stripe, separated by a gray interval. Variegation of upper parts descending 

 on sides of neck; sides of head with vague markings. Innermost secondaries showing quite 

 blackish in general field of upper parts, and edged all around with a firm border of ashy-white 

 or hoary-white. Greater and middle coverts exactly like inner secondaries ; prhnaries similar, 

 but the edging not so clear. Edge of wing clear yellow, and some of the least coverts tinged 

 with this color. Tail curiously particolored ; middle pair of feathers light grayish -brown, with 

 a strong dusky shaft-line throwing off numerous dusky cross-bars, so that these feathers seem 

 " watered " with lighter and darker shades. Other tail-feathers, except outermost pair, dusky- 

 brown, AA'ith pale grayish-brown terminal spots increasing in size from inner feathers outward. 

 On outermost feather this pale gray space is very large, and rimmed all around with white. 

 An indistinct maxillary stripe on each side of chin. A number of strong well-defined dusky 

 stripes on flanks ; otherwise, entire under parts unmarked, and of a dingy whitish color, clear- 

 est on belly and throat, more grayish on sides and across breast. Bill brown, pale below ; feet 

 pale. Length 6.00-6.25; extent about 8.25; wing 2.50; tail 2.75. Young: Similar, but with 

 a few drop-shaped streaks on jugulum and along sides ; feathers of upper parts with a more 

 appreciable terminal border of buft". Texas to California and southern Nevada, N. to Kansas 

 in summer, S. through New Mexico and Arizona into Alexico. Habits, nest, and eggs as in 

 P. crstivalis (eggs pure white, 0.75 X 0.55). 



H^MO'PHILA. (Gr. alixa, haima, blood; 0/Xof, lihilos, loving: what application?) Re- 

 lated to Peuccpxi; crown chestnut or rufous (in our species) ; no yellow on edge of wing ; eggs 

 not white. This is an extensive and varied genus of chiefly extralimital species, to which our 

 birds of the ruficeps group and carpalis group prove to be more closely related than they are to 

 the cestivalis group, arizonce, and cassini. This distinction, first indicated in Key, 2d ed. 

 1884, p. 374, under head of ruficeps, was confirmed by Ridgway, Auk, Jan. 1899, p. 80, and 

 formally adopted in A. 0. U. Suppl. List, ibid. p. 119, where the name of the genus is mis- 

 spelled ^'Aimophila,^^ as by Swainson, 1837.
