One specimen, a male in winter plumage, was caught 

 in Rånen (Nordland) at the beginning of 1889, (probably at the 

 end of January or the beginning of February), and is preserved 

 in the Bergen Museum 1 ; it was described and figured by Dr. 

 Grieg in the Bergens Museums Aarsberetning for 1889, No. 5, 

 with plate (Bergen, 1889). 



Another specimen of the same hybrid was found in Anger- 

 manland in Sweden 2 (Upsala Museum), and three in Finland 

 (Helsingfors Museum), all males. No instance of the occurrence 

 of a female has as yet been reported. 



One of the Finnish specimens was caught in Kittilå Lapp- 

 mark in November, 1890. In colouring it was almost exactly 



1 At the farm of Jordbro in the same district, at the end of November, 

 1897, a bird was shot that was possibly the same bastard. It was 

 described by the sportsman to whom I am indebted for the informa- 

 tion, as altogether resembling the "Rype-Orre" (a well-known bastard 

 form in these paris) in colour, but of the size of a female capercaillie. 

 It showed very little fear, and was shot in willow-grouse eountry, 

 sitting in a tree. It was not preserved.
