462 THE ZOOLOGIST. 
Stoat (Putorius sp.), although said to be fairly common round 
the coast—where the Rabbits have been driven by cultivation of 
the interior—I was able to obtain only one specimen, and that 
given me by afriend, nor have any others been taken since by 
those who promised to keep a look-out for it. This specimen 
was caught in a Mole-trap in Trinity, and presents a definite 
difference from either the English or Irish species, but Mr. 
Miller has been obviously unable to describe it as a distinct 
species until other specimens come to hand to confirm its 
peculiarities. 
Woop Movs (Apodemus sylvaticus) is about as frequent as in 
England, and shows no difference from the type. Up to the 
present there is no record of A. flavicollis. 
Hovsse Mouse (Mus musculus) occurs in its usual habitats all 
over the island. Specimens taken from the sandy soil of St. 
Ouens, where they are said to have occurred before the advent 
of houses, show a slightly sandy coloration. 
Brown Rat (M. decumanus) is as ubiquitous as ever. 
JERSEY VOLE (Hvotomys cesarius).— This interesting species 
has been recently described by Mr. Miller (Ann. Mag. Nat. Hist. 
February, 1908) from two specimens in the National Collection, 
taken by Capt. Barrett-Hamilton at St. Heliers in 1896. It is 
related, according to Mr. Miller, to EH. skomerensis on account of 
its possessing “‘a well-defined third re-entrant angle on the inner 
side of third upper molar,” but differs from that species in its 
‘‘shorter, more evenly cuneate nasals, broader rostrum, shorter 
tail, and much darker colour.” Specimens which have recently 
been sent to me show measurements slightly exceeding those of 
the type-specimens. For instance, one (female) taken at Trinity, 
Oct. 9th, measures as follows (the corresponding measurements 
of the type are added in parenthesis for comparison) :—Head to 
tail, 165 (145) mm.; hind foot, 18 (18); ear, 12 (11). Skull: 
Condylo-basal length, 27 (25°6) ; zygomatic breadth, 15°5 (14); 
interorbital constriction 4°1 (4); occipital breadth, 12 (11°6) ; 
occipital depth, 6°8 (7); nasals, 7°8 (7); diastema, 7°8 (7-2); 
mandible, 15°8 (15°4); maxillary tooth-row, 6°4 (6°2); man- 
dibular tooth-row, 6 (6). 
The following measurements are taken from eighteen males 
and twelve females :—
