464 THE ZOOLOGIST. 
Great HorsesHor Bat.—Recorded for Guernsey only, where 
it is common, but may possibly occur in Jersey also. 
BarBastELLe Bat ?.—A specimen (apparently of this species), 
now in the local museum, was taken from a cat in St. John’s 
Road, St. Heliers, Jersey, September, 1907. 
Brown Rat.— Has not yet appeared in Sark, where M. 
rattus occurs in great numbers. Since it is found even 
on isolated rocks around the island, one may suppose that 
the Black Rat has for once been successful in overwhelming 
its powerful brown competitor, probably owing to superior 
numbers. 
Buacx Rat.—Although abundant in Sark is getting rare in 
the other islands. The “Blue”? Rat, which occurs on the 
EKcrehou Rocks, a few miles north-east of Jersey, belongs to this 
species. The Black Rats on Herm are much stronger and more 
robust animals than those on Jersey or Sark, and have longer 
hair on their backs (85 mm.) than the latter. 
The Alexandrine Rat has been taken in Jersey. 
House Mousz. 
Lone-raiteD Fistp Movusr. — Occurs in Jersey, Guernsey, 
and Alderney. 
Fietp Voue.—Has not been taken in Jersey. 
Bank Vouu.—Probably occurs only in Jersey. 
Water Voute.—Once plentiful in Jersey, now rare. 
Ragpit.—At one time native in probably all the islands, 
but now hybridized by imported “‘ Belgian Hares” in Jersey, and 
by the English animals, which have so often been put down in 
Guernsey. 
Hare.—Was abundant in Jersey up till 1868, probably in- 
digenous, often added to from France, and now scarce. 
SQuIRREL.—Once indigenous, introduced several times during 
the last twenty years, now fairly numerous. 
Fox.—Was fairly numerous in 1850-60, and probably native, 
but is now extinct. 
Mr. Sinel, in a recent paper, read (October 21st, 1908) 
before the Guernsey Society of Natural Science, has dealt with 
the distribution of the Mammalia of the Channel Islands. 
It is interesting to notice, in this respect, that one finds on 
Guernsey a Microtus and a Crocidura, whilst on Jersey an
