 The second or black form of cock Grouse is, according to ISlr. 

 Ogilvie-Grant, rarely met with, most of tlie V)iack buds being 

 mixed with tlie red, or the white-spotted forms. 



In the Committee's Collection there ai-e a few very good ex- 

 amples of the rtuUy black tvjie, and they come from the folk. wing 

 areas : — Caithness, Sutherland, Pertiishire, Duuibarton.shire, and 

 Yorkshire. 



More or less typical examples have also heen obtained from 

 Ross-shire, Aberdeenshire, Morayshire, Kincardine, Stilling, 

 Fifeshiie, and Lancashire. 



At Newcastleton, the low-lying grassy ir,oors are credited with 

 the production of the black type of Grouse, while the other types 

 aie found on the higher heatlier-ground. 



The following specimen has been figured to illustiate the 1 lack 

 type of cock Grouse: — 



Plate LXXIX. Lender surface : black type in winter- 

 plumage. 

 ]\Tale Grouse, No. 723. Perthshire, 4.iv.07. 

 " The thii<l or ichite- spotted for 7n has tlie feathtis of the breast 

 and belly, and sometin;es those of the head and up|er])arts, tiji) ed 

 with white. The mo.st typical examples of this variety aie found, 

 as a rule, on the high grounds of the north of Scotland."" 



This statement is again confirmed by the Giouse Inquiry's 

 Collection, although an occasional white- spotted bird makes its 

 appeaiance farther to the south. It is, however, the exception in 

 the south, whether it be of the red or black or intei mediate type. 

 The most marked examples of this white-spotted form have 

 come from Caithness, Sutherland, and Inveiness, while IJunifries, 

 Perthshire, .and Yorkshire haxc tach piovided one oi- two very 

 fair examples. 



At Dingwall birils are said to be n;o>t connnc.nly dark I'ed or 

 l)lack with white beneath. 



At Scrafton, Middleham, the majority have whiti' beneath, and 

 all are dark red oi" bright red. 



The predominance of white beneath is quite coi;sj)icuous in 

 n geograpliical arrangement of a. large nund)er of skins, as a 

 cliaracter of the north of Scotland, especially throughout tlie 

 Higldands.

 Kpotted type of cock (!rousc : —
