450 THE ZOOLOGIST. 
Notes on Bats.—Mr. Kelsall has referred (Zool. p. 308) to a specimen 
of Daubenton’s Bat (which he kindly named for me) taken in Surrey. I 
may further state that at the time this specimen was captured (July, 1888) 
seven others were taken, and many more escaped. They were disturbed by 
poking a stick up a hollow apple tree at Cranleigh, and were caught in an 
insect-net. Mr. Kelsall also detected in my small collection two Whiskered 
Bats, Vespertilio mystacinus, obtained at Ratham, and I have since (Oct. 
18th last) obtained another specimen. The Noctule, perhaps for want of 
accurate observation, appears to have been less common of late years than 
formerly, when, as stated by the Editor (p. 244), I used to notice it in 
great numbers in August, and came to the conclusion that they were 
migrating, but this by my note-book appears to refer to the first week in 
August, 1863, and August 3rd, 1866. This year I saw none in August, 
nor in the preceding months, though during September, and as late as the 
18th of October, they were observed, but not in great numbers. The 
Pipistrelle is of course our common bat, and the Long-eared Bat is fairly 
numerous. I may add that, although searched for, no specimens of 
Daubenton’s Bat were found in the apple tree at Cranleigh during the past 
summers.— WILLIAM JEFFERY (Ratham, Chichester). 
Black Rat in Cornwall.—In your last number (p, 434) I recorded the 
occurrence of the ‘ Old English” or “ Black” Rat, captured at a place 
about five miles north-east of Penzance. Immediately after that capture 
a perfectly trustworthy observer saw near Camborne, at a place ten miles 
south-east from where my specimen was obtained, a Black Rit which was 
certainly not the ordinary Hanoverian Rat; and to-day I have seen and 
handled another specimen which is unmistakably the Black Rat, captured 
in Paul Parish, about three miles south-west of Penzance. ‘These facts appa- 
rently point to an incursion of this animal, which is gregarious certainly, 
and probably a vagrant in herds, but not a migrant.—Tuomas Cornisa 
(Penzance). 
BIRDS. 
The Marsh Warbler in Somersetshire.—About the middle of July, 
1888, during a visit to my home in Somersetshire, a young farmer friend 
brought me a nest, containing five eggs which puzzled me for some little 
time. At the first glance I took them to be unusually lightly coloured. 
eggs of the Reed Warbler, but the nest more resembled that of the Lesser 
Whitethroat, except that there was no wool in it. It then occurred to me 
that they might belong to the Marsh Warbler, Acrocephalus palustris, 
already recorded to have been found nesting in Somersetshire, some twenty 
five or thirty miles away (Zool. 1875, p. 4713), and turning up my copy of 
Seebohm’s ‘ British Birds’ on my return here, I found that they undoubtedly 
belonged to that species. The nest and eggs are there very accurately
