Co Merriam on Birds of the Adirondack Regioit. [January 



Pvas, PiJ^a, (Jv^w, I hoot, etc., from the root of j3or[, a ci-j, and cites Byzan- 

 tium, 'the place of owls.' 



No. 491. Ictinia. Here is a point on which Professor Merriam might 

 have thrown some light. We gave as probable radication ikfepd*;, a dis- 

 ease, in the idea of attacking; ictus, a blow, etc. Wharton says (1. c.) : 

 Perhaps froin the root ii<, to strike, as in if^, iT^f, a worm, iVvt], a wood- 

 pecker, icere, to strike, etc. ; but then adds, more probably from Skt. 

 9Jena, a falcon, as if *i-KJ€ivo§; cf. iKfig, a pole-cat, thief. 



No. 494. Accipiter. Should not Professor Merriam have helped us to 

 decide which of the alternative derivations we gave should be accepted .f* 

 Wharton gives wxtiTre'rqs, swift-flying, — thus making it formed on the 

 model of, and synonymous with, foxii'irtVT]S, Tachypetes. 



No. 498. Hierofalco, Gyrfalcon. Why could not Professor Merriam have 

 given us the benefit of his sound erudition on this.^ We advanced what 

 the 'Zoologist' reviewer calls an ingenious idea, very probably true ; but 

 it is against Skeat (whose 'Dictionary' we had not seen when we wrote the 

 'Check List'). The word seems to ti'ouble the etymologers, and no doubt 

 the ornithologists would be glad to have them settle it among themselves. 



( To be concluded.)

206. Turdus aliciae bicknelli. Bicknell's Thrush. — In my cabinet is a 

 specimen of this recently described Thrush which I shot in Lewis County, 

 near the western border of the Adirondacks, May 24, 1S78. It is a male 

 of the preceding year and its scapulars still show several (four on one 

 side and one on the other) of the light tear-shaped spots so characteristic 

 of immaturity in this group of Thrushes. Following are its measure- 

 ments : —
