104 PROCEEDINGS OF THE 



HOUSE MOUSE. 



Mus musculus, Lin. 



Common. It would appear that this species also frequents the 

 cropped fields, because in harvest time they become much more 

 abundant in the houses. 



Rodentia. Arvicolidae. 



COMMON FIELD VOLE. 



Arvicola agrestis, De Selys. 



Occurs in North Uist and in South Uist. No mention is made of 

 it by Macgillivray or previous writers, and considerable confusion 

 existed concerning the Yoles and Shrews of the Long Island, until 

 in June, 1879, I fortunately succeeded in obtaining specimens of 

 both for identification. This species is extremely abundant all over 

 the hills, and in the "machars" or sandy meadows, and their 

 runs in the grass are found to cross and recross in a perfect net- 

 work in certain favoured localities. The shepherd dogs take great 

 delight in hunting for them, and eat them with great relish. In 

 autumn they are most abundant in the lower ground and around 

 the farms, but in summer they are found all over the more unin- 

 habited parts equally numerous. 



Rodentia. Leporidae. 



13. BROWN HARE. 



LErus europaeus, Pall. 



Introduced into Harris at Rodil, becoming very numerous, and 

 numbers could be seen at one time crossing and recrossing the road 

 between Rodil and Borve; but prior to 1870 they were much 

 scarcer, and when I was there in that year I did not meet with a 

 single example. In 1879, however, they appeared more abun- 

 dantly, and, I was informed, had again largely increased. 



Hares occurred in Lewis as early as 1842.* 



They were also introduced into Barra, according to John 

 Macgillivray. f 



Buchanan puts on record the positive fact of the entire absence
