507. F. e. rlch'-ard-s6n-l. To Sir Jolin Richardson, tlie species having been described and 



figured in the Fauna Boreali-Americana. 



508. F. spar-vg'-n-us. — Post-classic Latin, meaning, relating to a sparrow, as columhanus from 



columba. There is a quasi-Latin word sparvins, from whicli sparverius is directly formed. 

 The word sparrow in some of its forms doubtless antedates any corresponding word in 

 the South European languages. We have not traced the Latin sparvius or sparveriua 

 back of Gesner, 1555. See Passer, No. 192. 



509 F. s. i-sa-bel-li'-nus. The Lady Isabel, having confidence in her husband's prowess, 

 vowed not to change her chemise until that warrior had taken a certain town. He was 

 longer about it than she expected, and she wore the garment until it assumed a peculiar 

 brown tint : hence the term " isabel-color " ; whence quasi-Latin isabellinus. 



510. F. spar-ve-rl-o-i'-des. This is an aggravated case of bastardy. Anglo-Saxon and Gothic 



spariva or sparra, Latinized as sparvius, a sparrow, whence sparverius, a sparrower, so to 

 speak, or sparrow-catcher, as tliis hawk is ; with tlie Gr. elSos, to denote the resemblance 

 of the West Indian to the North American bird. 



Not in the orig. ed. of the Clieck List. Lately said to have occurred in Florida. 

 See Ridg., Pr. Nat. Mus., iii, 1880, p. 220. • 



511. F. fijs-ci-coe-rial-es'-cens. 'La.t. fusciis, dusky, and ccErw/escens, growing blue; z. e., being 



bluisli: cceruleus, blue. This was wy'Mqii fuscoccerulescens by Vieillot, but the above is 

 preferable. " Femoral " relates to the color of the thigh ; femur, the tliigli-bone. 

 This is F.femoralis of the orig, ed. See Sharpc, Cat. Accip. Br. Mus., i. p. 400. 



512. Bia'-tg-6 u-nl-clnc'-tus har'-rls-i. Lat. huteo, a buzzard-hawk; of doubtful etymology; 



tile word occurs in Pliny. — Lat. uni, once, and ductus, girded ; unus, one, and cDirjo, I 

 gird, bind about; with reference to the single zone of white color on the tail. — To 

 Edward Harris, of Philadelphia. 



513. B. al-bo-caud-a'-tiis. — Lat. (7ttH.s, white, ca((c/fT^75, tailed; cauda, tuil The latter part of 



the word being a participial adjective of a supposed verb caudo, permits albus to be in the 

 "ablative of instrument," "white" being tliat wherewith the bird is "tailed." In 

 another form, it would be albicauda, like albicilla for instance. See No 42. 



Not in the orig. ed. ; since discovered in Texas both by G. B. Sennett and J. C. 

 Merrill. See Cones, The Country, July 13, 1878, p. 184; aud Ridg., Pr. Nat. Mus., i, 

 Oct. 2, 1878, p. 154.
