with Mr. Pycraft he had recently spent some weeks in 

 making a minute examination of the hundreds of Grouse- 

 skins procured by the Committee of the Grouse Disease 

 Inquiry^ and also of the large series of skins in the Natural 

 History Museum. In none of these birds could any 

 trace be found of the partial spring-plumage described by 

 Mr. Millais. Mr. Grant said that in getting together the 

 Museum series of Red Grouse he had received about twelve 

 male and twelve female birds killed in each month from 

 January to May, and that the males, though subjected to 

 a minute examination in the flesh, showed no trace of moult 

 until the autumn-plumage began to make its appearance 

 towards the end of May or beginning of June.

 conclusions. 



Mr. W. R. Ogilvie-Gkant exhibited an example of a new 

 species of Flycatcher which he described as follows : — 



Tarsiger elgonensiS; sp. n. 



Adult male. Similar to T. orientalis, Fischer & Reich., 

 but with the outer tail-feathers black except at the extreme 

 base, which is yellow. In T. oi'ientalis the yellow colour 

 extends over the basal three-quarters of all the tail-feathers 

 except the middle pair. Iris dark brown ; bill black ; feet 

 dull green. 



Wing 3' 3 inches. 



Hab. Mount Elgon, 7000-9000 ft., B. E. Africa. 



Obs. The species was first procured by Mr. F. J. Jackson, 

 but was not distinguished from the allied T. orientalis. 

 Subsequently it was obtained by Mr. Robin Kemp, the 

 naturalist on the Rudd Expedition to B. E. Africa. 



Mr. J. H. GuRNEY exhibited two Seventeenth Century 

 prints of the Bass Rock from Sleezer's ' Tbeatrum Scotise,' 

 and remarked on the diminution in the number of Gannets 

 which in the time of Sleezer and John Ray bred on the
