80 MR. W. OSBURN ON THE BATS OF JAMAICA. ([Jan. 24, 
the lens, proved to be entirely composed of fragments of the harder 
portions of insects; a portion at the surface was agglomerated in 
the usual form, but by far the largest part completely disintegrated 
and dry. Those not dead crawled actively on the grass, climbed upon 
clothes ; one little fellow I captured between my coat and waistcoat. 
Their object was evidently to escape the light. They bit fiercely at 
my fingers, and drew blood with the sharp little canines, and made 
a squeaking bird-like chirp when put into the bag. Several got up 
from the grass for a few inches, but soon fell again after hovering 
with great exertion; when thrown three or four feet from the 
ground, flew easily. I noticed that with this species, when thus 
flying by day, the arc of the stroke was about a sextant, as much 
above the body as below. Several of the females were pregnant 
with one foetus.” 
“‘ Mount Pleasant, St. Anne’s, 14th June, 1859. 
** The roof here is largely inhabited by Bats; Dr. Rose thought, 
by two species—a long-eared (Macrotus?) and asmall one. Towards 
dusk I went out, anxious to ascertain what they were; but the little 
creatures were extremely cunning. Their place of egress was beneath 
the shingles of a low house. Though we could hear them scratching 
about, they always darted out at an unguarded point, and it was 
some time before the chaise-whip brought one down. It proved 
to be this species. There were no Long-eared Bats that I saw. I 
suspect my friend was mistaken.” 
“ Freeman’s Hall, 4th July, 1859. 
** T observe, in looking over my specimens, that, besides the lips 
being fringed with ordinary stiff cilia, there is in the considerable 
space between the nostrils and edge of the lip a tuft of very singular 
bristles ; they are very short and thick-set, and beneath the glass 
are seen to be spoon-shaped. I have no idea of the use of these, 
unless it be to aid in retaining struggling insects. Some cotton, I 
put the Bats in, was attached very firmly by the hooks.” 
“ Windsor (Trelawny), 30th May, 1859. 
On a foetus of this Bat I note as follows :— 
* Milk-teeth not through, but in lumps on gum. 
“© Molars = Gjp—a ak = 
1—P 
** Molars in the position of anterior pair of false molars. Lower 
limbs most developed ; two exterior toes on each foot largest ; outer 
toes of each foot set on lower than the rest, like a thumb. Naked.’ 
Stomach of adult a lengthened membranous sac, thin, and, when 
empty, with difficulty distinguished from intestine, except by its 
rather wider diameter. No trace of internal plicee. Male distin- 
guished by a large gular gland, 3, in. in width. Made a loud chirp- 
Ing noise in captivity. Would not drink : rejected the flies I offered, 
and bit fiercely. The large size of the outer toe seems a distinction 
from Nyctinomus (no. 1). When about to bite, the ears are brought 
down; but they are ordinarily kept erect.
