Animals -- Great Britain
One feels inclined to apologise for the poverty of language displayed
in the heading above; though no one accepts responsibility for it--the
fault lies with the Law of Priority. A strong point in the Linnean
System of nomenclature was its binomial character--there were two
words only in the name of every animal and plant, the first of the two
indicating the genus in which it was grouped, and the second peculiar
to the species. In recent years the extension of our knowledge of the
world's fauna has led to the breaking up of many of the older genera
and a regrouping of the species. In some cases the species name has been
adopted to denote a new genus, and then the Law of Priority steps in
and says the oldest species name must be retained, so that instead of
a binomial we get a mere duplication. When this happens--as above--to
be essentially the same as the only "popular" name the species has ever
had the result is ludicrous.
Daubenton, who first described it (1759), called it the Bearded Bat (La
Barbastelle) owing to tufts of black bristles on the glandular swellings
on the muzzle. It is of slender form with long legs and small feet. The
irregularly four-sided ears are relatively large, as broad as long, and
united by their bases just behind the muzzle. The outer border has a
deep notch; the lance-shaped tragus is half the length of the ear. The
nostrils open in a naked depression.
The long, soft fur is a very dark brown, but many of the hairs on the
upper surface have pale tips which produce a frosted appearance; on
the lower surface such light tips are more numerous, and are specially
evident along the middle line of the abdomen. The wing, ear, nose, and
foot are dusky, appearing lighter than the furred regions.
The head and body measure about two inches, and the tail an inch and
three-quarters. The expanse of wings is about ten and a third inches.
This and the Long-eared Bat are the only British species whose ears
connect; and the form of the ear in each is so distinct that there is
no danger of confusing them. It is both solitary and silent in flight,
which begins early in the evening, often in daylight; it holds its
feet far apart and the tail decurved. In fine weather it flies high.
During its diurnal rest it has been found in various retreats, often
in company: under thatch of a shed, between the rafters and tiles of
outhouses, behind a cottage shutter, in the crevices of walls and trees.
Its voice is a metallic squeak or a buzz.
It has one premolar less on each side than the Long-eared Bat, so that
its dental formula stands thus: _i 2/3, c 1/1, p 2/2, m 3/3 = 34_.
As a British Bat, the Barbastelle is found chiefly in the South of
England, though it has been recorded from all the English counties
between the Severn and the Wash; also Lincoln, Cheshire, and Cumberland
(Carlisle). It appears to be absent from Scotland, Ireland, and the Isle
of Man.
