ZOOLOGICAL NOTES. 



Lesser Shrew in Perthshire. On igth November 1910, a 

 Lesser Shrew (Sorex minutus] was found lying dead on a path in a 

 larch wood, on the estate of Baledmund, near Pitlochry. We sent 

 it to the Royal Scottish Museum, where our identification of it was 

 confirmed. As there are only two direct records of this species in 

 Mr. Harvie-Brown's " Fauna of the Tay Area and Strathmore," we 

 think this occurrence may be worthy of a note. LEONORA JEFFREY

Melanie Variety of the Orkney Vole. During my last visit to 

 Orkney, I saw several black specimens of the Orkney Vole, a pair 

 of which are now to be seen in the Stromness Museum. There 

 appears to be only one very small colony, or even family, known, and 

 known only to one man, who procured these specimens, but who will 

 not divulge their locality, except that it is on the mainland of Orkney 

 and not far removed from Stromness. H. W. ROBINSON, Lancaster. 



[I have captured what appeared to be partially melanic examples 

 of this Vole near Stromness, but these on examination proved to 

 be merely in moult. I do not wish, however, to suggest that the 

 specimens to which Mr. Robinson refers were not in full fur and 

 are not melanisms. The under fur of this species is black, and 

 when the longer hairs are moulted this under coating becomes very 

 evident. I have moulting specimens which approach being entirely 

 black. W. E. C.] 



The Birds of St. Kilda. In order to carry the investigations on 

 the migrations of birds, in which I have been for some years en- 

 gaged, to the outermost fringe of the British Area, I visited St. Kilda 

 during the past autumn. Here I remained, with George Stout as my
