I. RECENT SPECIES. 



Order I.: CHIROPTERA. 

 Family: VESPERTILIONIDAE. 



1. Plecotus auritus (Linnaeus). 



Long-eared Bat. 



Not uncommon in the southern and central counties, but rarer 

 in the north. It occurs in Arran, Islay, Mull, and probably in 

 the other Inner Hebrides, but has not been recorded from the 

 Outer Islands, nor from Orkney or Shetland. 



[Rhinolophus hipposideros (Bechstein). — The Lesser Horse- 

 shoe Bat is stated by Dr. A. R. Young to have occurred, along with 

 the last species, at Crookston Castle, Renfrewshire (New Stat. Ace. 

 Renfr., p. 162). All inquiries as to the fate of the specimen have 

 been in vain, and I greatly suspect a mistake in identification.] 



2. Vesperugo pipistrellus (Schreber). 



Common Bat. 



Scot., Bak, Bakie, Backie-bird (Swed., Natt-baka, a bat; Old 

 Norse, blaka, to flap) ; Gael., Ialtag, Dialtag. 



Much the commonest species of Bat in Scotland, extending 

 quite to the north of the mainland, but rare in some localities, as 

 in the west of Sutherlandshire, where I have only once seen a 

 specimen. It is common in Arran, Islay, and Mull, but appears 

 to be scarce in the Outer Islands. The late Capt. M 'Donald, of 

 Rodil, told Mr. Harvie-Brown that he had only once seen a Bat 

 in Harris, and Baikie and Heddle mention a few instances of 

 their occurrence in Orkney (Hint. Nat. Ore, p. 14). 



[Vesperugo xoctula (Schreber). — Fleming identified the Vesper- 

 tilio auriculatus of Walker's "Fauna Scotica" (Essays Nat. Hist., 

 p. 472) with this species (Brit. An., p. 6), but the description agrees 

 much better with V. daubentoni. The Great Bat is also stated bv 

 the late Sir William Jardine to have been seen near the River 

 Annan, in Dumfriesshire (New Stat. Ace. Dumfr., p. 175), but its 

 occurrence in Scotland has not been confirmed. The most northern 

 English locality which has been recorded is Northallerton, in York- 

 shire (BelVs Brit. Quad., 2nd ed., p. 23).]
