The downy chicks of tbis form, which is rather common on the main- 

 land of Kamtschatka, have not yet been described so far as I know. I 

 was fortunate enough to obtain two, the larger of which may be de- 

 scribed as follows : 



Pullus (,U. S.Kat. Mus., No. 92705; L. Stejneger, No. 2300. Fetropaulaki, Earn., begin- 

 ning of July, 1883). 



Above pale rusty ochraceous, more or lees spotted with blackish ; underneath pale 

 buff, more yellowish on jugulum and abdomen, unspotted ; the spots on the upper 

 surface are arranged as follows : On the forehead an arrow-shaped blackish spot and 

 a double one on the lores ; just on the border betweeu forehead and crown a large 

 horseshoe shaped spot with the opening turned toward the beak; on the crown a 

 somewhat indistinct cross-streak, and a similar one across the nape ; on the ear-coverts 

 two very disitinct spots, and behind them, on the side of the neck, a larger rusty 

 brown spot circumscribed by black ; along the middle of the hind neck a longitudinal 

 streak ; back more or less mottled with dusky, which color on the posterior part of 

 the back forms into two indistinct parallel longitudinal bands of a more rusty hue. 

 The remiges and the larger coverts are out, with more or less regular mottlings of 

 dusky and pale rusty in both webs and broadly margined with rusty cream-color, 

 which also runs up along the shafts; the tips of the light margins of the great 

 coverts are nearly white, so as to form a conspicuous band across the winij. Chin, 

 throat, and tibiae pale buff, as the rest of the under surface, and without dark raark- 



The two specimens are exactly alike in every particular.

ties. There are apparently at least two forms in Europe (being now without suflQcient 

 material, I shall only hint at Tetrao eremita, described in " Svenska Vetenakaps Aka- 

 demiens Handlingar for 1789 " (p. 179), which is " smaller than the usual bird, and ashy 

 gray, with somewhat darker head and neck "), and one East Siberian variety which may 

 be called UrogaUtis urogaUus taczanoivsldi. It is described by Mr. Taczanowski thus: 

 " Les m^les obtenua d'Irkutsk se distinguent par piusieurs details des oiseaux de 

 I'Europe, c'est-a-dire : ils out les pattes beaucoup plus velues, et les doigts converts 

 jusqu'a la derni^re articulation ; ils out le bee un peu plus court, plus renti6 sur lea 

 c6t6s au devant des narines ; lo plumage en g^n^ral plus niou avec un dessiu g^n^- 

 ralement pins fin. Les femelles ont les plumes des pattes plus aboudautes que dans 

 les femelles europ^ennes, mais la diffdrence n'est pas aussi grande que chez les miles ; 

 leur bee est aussi plus large a la base " (Bull. Soc. Zool. France, 1876, p. 243). The 

 other species is UrogaUus parvirostris (Bp.) with its two subspecies U. parviro^tris 

 Aaj>i(«c/iaHc((8 (KiTTL.), and UrogaUus parciroatris saehaUnensis (Bogdanow) {Tetrao 

 vrogaUoidis var. j3. sachaUnensis Bogdan.. Consp. Av. Imp. Ross., I, 1884, p. 122).
