314 MAMMALS OF ARRAN. 



2. Long-eared Bat (Plecotus auritus, LINN.) Common. 



3. Common Shrew (Sorex vulgaris, LINN.) Common. 



4. Black Water-Shrew (Crossopus fodiens, PALL.) The dark 

 race of the water-shrew (often, described as a distinct species 

 under the name of C. remifer) is not uncommon in the burns 

 near Loch Ranza. This variety is pretty widely spread 

 throughout Scotland, while the white-breasted race seems to 

 be very rare or local Specimens intermediate in character 

 are often taken. 



5. Otter (Lutra vulgaris, ERXL.) Common. Except tame 

 cats run wild, and rats, this is the only sort of " ground 

 vermin " found in Arran. 



6. Common Seal (Phoca vitulina, LINN.) Sometimes seen, 

 but is not plentiful on any part of the coast 



7. Porpoise (Phoccena communis, F. Cuv.) Frequently 

 seen in pursuit of the shoals of herrings. Other species of 

 cetaceans may perhaps visit the coast, but I am not aware 

 that any have yet been recorded. 



8. Brown Rat (Mus decumanus, PALL.) Abundant, both 

 in houses and in the open country. Mr. Halliday observes 

 that, when hunted, it takes to water as freely as the true 

 water-vole. 



9. House Mouse (Mus musculus, LINN.) Common. 



10. Wood Mouse (Mus sylvaticus, LINN.) Common. 



11. Common Field-vole (Arvicola agrestis, LINN.) Com- 

 mon. The red field- vole (A. glareolus, SCHREB.) may pos- 

 sibly be also found, for it is widely distributed in Scotland. 

 Mr. Halliday has never seen the water-vole (A. amphibius, 

 LINN.) in Arran, and believes that it is not a native of the 

 island. 



12. Common Hare (Lepus timidus, LINN.) Common in 

 suitable places, but is believed to have been introduced from 

 the mainland. It is not mentioned by Pennant. 



13. Rabbit (Lepus cuniculua, LINN.) Rabbits must have 

 been introduced before 1772; for they are included by 

 Pennant among the quadrupeds of the island.
