spending to F. gyrfalco of Continental Europe, without raising the much-vexed question 

 of their identity. We give the dark Labrador bird as a variety of tliis, and tlie Ice- 

 landic and Greenlandic as both specifically distinct; thougli we suppose all the nortiiern 

 Hierofalcones to be but geographical races of a single species. 



499. F. s. 6b-s61-e'-tus. Lat. o/«o/c<((s, unaccustomed, unwonted, disused, obsolete; here refer- 



ring simply to the ill-defined character of the markings ; ob and soleo, 1 am accustomed. 



Not in orig. ed. This is Falco labradoms of Audubon, lately accredited by Mr. Eidg- 

 way with varietal distinction, and identified with F. obsolctus Gm. 



500. F. is-land'-i-cijs. [ees-]. Latinized directly from the native name of Ice-land (Island, 



otherwise known as Eisland and Ijsland), and thus meaning Icelandic, — not "in- 

 sular." 



501. F. can'-di-cans. Lat. ca??c?/co, I am white ; present participle of the verb ; candidus,\\\\\iQ\ 



cundeo, I am sliining, &c. Candid is pure, clean, hence truthful; candescent, brilliantly 

 glowing; candidates were so called because clothed in white; candles give light; canescent 

 hairs grow white ; in all these, and countless words, the same root is seen. 

 In the orig. ed. as Falco sneer var. candicans ; see above, No. 498. 



502. F. mex-i-ca'-nus. To Mexico, whence Lichtenstein described it. It has been identified 



witli F. poli/a;jrus of Cassin. " Lanier " or " Lanner " is the name applied in ornithology 

 and falconry to certain Old World species ; it is from laniarius, of a butcher, laniatur, a 

 butcher, from lanio, I lacerate, mangle; lanitis (which see, No. 186) is the same thing. 



503. F. pgr-g-gri'-niis. See Hehnintliophaga, No. 109. 



This stands as F. communis in the orig. ed. It is well to stretch a point in favor of 

 Tunstall, 1779, to be able to restore this well-known name. 



504. F. p. peal'-T-i [in three syllables]. To Titian R. Peale, of United States Exploring Expe- 



dition fame. Of doubtful standing. 



505. F. c61-Qm-ba'-rI-us. Post-classic Lat. columbarius, pertaining to a pigeon, co/wmta ; or, a 



pigeon-fancier, as this spirited little falcon is. 



506. F. c. suck'-16y-i. To George Suckley, known in ornithology for his researches in Oregon 



and Washington Territories. The first syllable is long, and pronounced with the full 

 Latin force of j2, like oo in moon. A very dubious bird.
