90 PROCEEDINGS OF THE 



which occur in Scotland, seven occur in the Inner Hebrides, and only 

 six in the Outer Hebrides, while Ireland contains no less than twelve. 



Of the twelve in Ireland, one I consider doubtful as an indigen- 

 ous species, viz., the Squirrel — Sciurus vulgaris. My reasons for 

 doing so cannot be given in this place, as they involve too long a 

 discussion for this paper. 



To five previously recorded in the Outer Hebrides I am now 

 able to add the sixth — Sorex minutus. 



We gather the general information from these comparative lists 

 that the semi-aquatic Otter, and the wide-ranging, swift Deer were 

 those animals — not purely oceanic — which had the earliest and 

 widest distribution in the Long Island amongst now-existing 

 species. Next in order probably come some of the smaller rodents, 

 and then the Marten. The Rabbit cannot be taken into this con- 

 sideration, as it was an introduced species. 



The following is a list of the various works treating of the 

 Outer Hebrides which have been found more or less useful in this 

 connection, as well as of others which I have not had an opportunity 

 of examining : —

 Scotland."
