OENITHOLOGICAL EXPLORATIONS. 319 



TETEAONOIDE^. 



104. Urogallus parvirostris kamtschaticus (Kittl.j (p. 192). 

 ? ? Falcipennis falcipennis (Hartl.). 



Occasionally ' ' Kamtschatka " is given as the habitat of this species. It seems not to 

 occur there, however, and the statement is probably clue to some earlier author who 

 ignorantly supposed that all the countries surrounding the Okotsk Sea belonged to 

 Kamtschatka. It must be remarked, however, that also Bogdanow (Consp. Av. Imp. 

 Eoss., I, p. 30) (1884) gives Kamtschatka as the habitat of this bird. 

 ? ? Bouasa albigrularis Brehm. 



Brehm, in Naumannia, 1855, p. 287, described it in the following words: "Bonasia 

 albigularis, mento albo. Kamtschatkalis." In J. f. Orn., 1860, p. 393, is a statement 

 that the specimen was originally brought from Kamtschatka by Tilesius. No one 

 else has found the Hazel Grouse in Kamtschatka. The specimen may be from Siberia, 

 though, and is possibly identical with Menzbier's B. griseiventris, in which case 

 Brehm's name would have priority ; even Pallas says, " in Camtschatca, Stellero 

 observante, deest." 



" Graue Eebhiiner befinden sich allein um Werchoi Ostrog, doch sehr selten" (Steller, 

 Beschr. Kamtsch., p. 193.) Gray Partridges! May they not, perhaps, be one of the 

 two mentioned ? 



105. Lagopus lagopus (Lin.) (p. 194). 



106. Lagopus mutus (Montin)? 



Taczan., B. S. Z. F., 1883, p. 338.— i. alpinus Bogda^'., C. A. L R., I, p. 

 33.— Dyb., B. S. Z. F., 1883, f). 368. 



The Ptarmigan found in the mountains of the peninsula has not been 

 satisfactorily determined. It would be no surprise if it should prove 

 to be distinct. It is pretty safe to say, however, that it is not typical 

 mutus. 



107. Lagopus ridgwayi Stejn. (p. 194). 



ACCIPITROIDEiE. 



108. Falco rusticolus Lin. (p. 203). 



109. Falco islandus BrxJnn. (p. 204). 



110. Falco pealei Ridgw. (p. 206'). 



111. Falco peregrinus Tunst. ? 



Taczan., B. S. Z. F., 1883, p. 330. 

 The description of an adult male given by Taczanowski seems to 

 indicate F. pealei. The exact identification cannot be made without 

 examining the specimen, and F. peregrinua is therefore retained with 

 a query.
