dori was correct in stating (Ibis, 1893, p. 466) that the 

 species is quite different from C. novce-zelandice, and tliat 

 C. rayneri is identical with C. cooki — the proper name of the 

 Norfolk-Island bird. It would seem that the species of 

 this genus, which formerly inhabited Lord Howe Island, has 

 become extinct. 



22. Ogilvie-Grant on the Changes of Plumage in the Red 

 Grouse. 



[Ou the Changes of Plumage in the Red Grouse {Lagopus scoticus). 

 By W. R. Ogilvie-Grant. Ann. Scottish Nat. Hist. 1894, p. 129.] 



We may fairly presume that no living ornithologist knows 

 more about the various plumages of the Red Grouse of 

 Scotland than Mr. Ogilvie-Grant, and that his views are 

 entitled to respect, if not to acquiescence. The results that 

 he has arrived at are as follows : — " The male has no distinct 

 summer-plumage, but has distinct autumn- and winter- 

 plumages, and retains the latter throughout the breeding- 

 season. 



" The female has a distinct summer-plumage, which is 

 complete by the end of April or the beginning of May : also 

 a distinct autumn-plumage, which is retained until the 

 following spring. 



'^To put it more shortly, both male and female have two 

 distinct moults during the year, but in the male they occur 

 in autumn and winter, and in the female in spring and 

 autumn ; the former having no distinct spring- and the 

 latter no distinct winter-plumage.^' 



These remarkable facts, which the author believes to be 

 without parallel in ornithology, are fully explained in the 

 present article, and illustrated by useful coloured plates.
