507. F. e. rich'-ard-s6n-I. To Sir John Richardson, the species having been described and 



figured in the Fauna Boreali-Americana. 



508. F. spar-v6'-ri-us. Post-classic Latin, meaning, relating to a sparrow, as columbarins from 



cohtmba. There is a quasi-Latin word sparvius, from which 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 span-erius 

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



509 F. s. I-sa-bel-H'-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-v6-rT-8-i'-des. This is an aggravated case of bastardy. Anglo-Saxon and Gothic 



spurwa or sparra, Latinized as sparvius, a sparrow, whence sparrerius, a sparrower, so to 

 speak, or sparrow-catcher, as this hawk is ; with the Gr. eI5os, to denote the resemblance 

 of the West Indian to the North American bird. 



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

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



511. F. fus-ci-coe-rul-es'-cens. Lat. fuscus, dusky, and cosrulescens, growing blue; i. e., being 



bluish: cceruleus, blue. This was written fuscocaerulescens by Vieillot, but the above is 

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

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



512. Bu'-tg-5 u-nl-clnc'-tus har'-rls-i. Lat. bntco, a buzzard-hawk; of doubtful etymology; 



the word occurs in Pliny. Lat. uni, once, and cinctus, girded ; units, one, and cingo, I 

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

 Edward Harris, of Philadelphia. 



513. B. al-b6-caud-a'-tus. Lat. albus, white, caudatns, tailed; cauda, tail. The latter part of 



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

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

 another form, it would be albicaudn, 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; and Ridg., Pr. Nat. Mus., i, 

 Oct. 2, 1878, p. 154.
