64 MAMMALS. 



the Long Roads ( 1 Hope), of which South Ronaldsay forms the 

 eastern breakwater. Very many exotic insects are introduced 

 by vessels at Liverpool and other sea-ports, and bats can hide 

 in a corner, and do without food in cold weather almost as well 

 as an insect. I hope the reasons I have now stated will serve 

 to explain my contentment in looking upon this bat as an 

 intruder." John Wolley, Edinburgh, December 15, 1849. 1

 autumnal straggler to Bermuda. J. M. Jones, The Naturalist in 

 Bermuda, p. 13 (London, 1859).

 Newton, who kindly took the trouble to work out the history 

 of the specimen. 



Order INSECTIVORA. 



Family ERINACEIDJE. 

 Erinaceus europaeus, L. Hedgehog. 



Mr. Irvine-Fortescue was told that a few Hedgehogs were brought 

 to Orkney by the sons of Dr. Logic, minister of Dirleton, and 

 turned out about 1870. There seems to be no word of them 

 since. 



Family SORIOIDJE. 

 Sorex tetragon urus, Herman. Common Shrew. 



Orc.=Rone Mouse (J. G. M.-H.). Sheer-Mouse (B. and H.). 



Messrs. Baikie and Heddle consider this species as not very 

 numerous, but the late Mr. J. G. Heddle found it common in 

 Walls. 



Mr. Irvine-Fortescue has seen dead Shrews occasionally about 

 Swanbister, and has also seen and heard them in Hoy. 



1 Tom. cit. 2813, 2814. [" A very minute description of the Ronaldsay specimen 

 is given by J. Wolley, which occupies nearly two pages. The specimen is sup- 

 posed to be in the Cambridge Museum, but Wolley seems to have had others for 

 comparison, and, as none appear to have been labelled, the Orkney specimen 

 cannot easily be picked out now.]
