416 THE ZOOLOGIST. 
The Squirrel (Sciwrus leucurus, Kerr) appears to be extend- 
ing its range in Cornwall. It is at present abundant throughout 
the Truro-Falmouth district, but seems to be absent from the 
west and south-west, while in many parts of the east and north 
of the county itis scarce or altogether wanting. The Dormouse 
(Muscardinus avellanarius, L.) is widespread but local. Though 
apparently scarce in the Hayle, Camelford, and Callington 
districts, it is common in places about Helston, Falmouth, 
Truro, Lostwithiel, and Liskeard. Up till three years ago it was 
fairly common about Newquay, but lately has become scarce. 
The Brown Rat (Mus decumanus, Pall.) is generally distributed 
and much too common. Pied varieties are not uncommon, and 
an albino was killed by Mr. Henry Harris near Stratton in 1901. 
The Black Rat (M. rattus, L.) was several times recorded from 
the county by T. Cornish between 1878 and 1889, and especially 
from the Penzance district. In August, 1891, one was killed 
near Falmouth by a farm lad, and seen by the writer in the 
flesh. There seems to be no further county record till 1902, 
when one was caught in a trap and another seen at Heamoor, 
about two miles north-west of Penzance. In June, 1907, a very 
old male was captured at Paul, three miles to the south-west of 
the same town. A fine female of Mus alexandrinus was killed in 
the Falmouth Docks on June 30th, 1900. The House Mouse 
(M. musculus, L.) is abundant, and so, too, is the Long-tailed 
Mouse (M. sylvaticus, L.). The diminutive size and unobtrusive 
habits of the Harvest Mouse (M. minutus, L.) have caused it to 
be generally overlooked, and consequently its county distribution 
has not been worked out. It is locally fairly common about 
Penzance, and two examples have been captured at Hayle and 
one at Helston. Several young specimens were brought in from 
Pendarves by mining students at Camborne. About Falmouth 
and Truro it is local, but in places very common. About a 
dozen were obtained one day in a stackyard at St. Breward, and 
it is known to occur at Bodmin, Egloshayle, and Lostwithiel, 
so that it is evidently well represented in the middle of the 
county. Specimens have been obtained at St. Neot and at 
’ Launceston, but on the north coast it is either scarce or very 
local, as the only examples seen were from Mawgan and Kast 
Pentire, Newquay.
