PTARMIGAN. Lagopus mutus (Montin). Length, 14 

 in. ; wing, 7 "5 in. ; tarsus, 1-25 in. 



Resident only on the higher mountains of Scot- 

 land and the Hebrides. The best hills for Ptar- 

 migan in Scotland are in Ross-shire around Loch 

 Maree, and in the Auchnashellach Forest; Sutherland, 

 Caithness, and parts of Perthshire. Formerly in the 

 Isle of Rum, and in S.W. Scotland — Kirkcudbright- 

 shire and Dumfriesshire (Service, Zool., 1887, p. 81). 

 In Orkney the last were shot in Hoy in 1831. 



As to its alleged former occurrence in Cumber- 

 land, see More, Zool., 1881, p. 44, and Macpherson, 

 "Fauna of Lakeland," 1892, p. 333. The assertion 

 that Ptarmigan once existed in Wales is without 

 foundation (Zool., 1881, p. 45). 



As to hybrids between Ptarmigan and Red 

 Grouse, see P. Z. S., 1878, p. 793, and Zool, 1892,
