74 MR. W. OSBURN ON THE BATS OF JAMAICA. [Jan. 24, 
be arranged, even though putrefaction has not yet commenced in 
the stomach.” 
“ Freeman’s Hall, 21st July, 1859. 
“One of these Bats entered the house this eveuing; and though 
the room is small and very low, it was only after a long chase I suc- 
ceeded in taking it, from its extreme rapidity and agility of wing. At 
length it was completely tired out, and allowed me to take it by hand. 
I placed it under a candle-shade, where it made constant efforts to 
escape by jumping. It easily took wing off a flat suface, and its 
efforts to escape during the night broke some of the phalangeal 
bones; but, notwithstanding, on the cover being removed, after one 
or two efforts it succeeded in jumping out at the top. It refused 
flies I caught and offered it, shaking its muzzle at them with evident 
dislike; but it drinks greedily. The tongue was protruded; but the 
water taken up by it and the foliations of lips was sucked in with the 
head raised, by an action very like chewing.”

containing a yellowish mass with fragments of harder parts of insects 
interspersed. I recognized two short legs, with powerful double 
claws attached. These, from what I subsequently observed, I have 
reason to believe were those of Orthoptera. 
Dental formula, M. =, C. =, I. 4 =34. 
Incisors. Upper, middle large, edges rounded ; lateral minute, 
only visible with glass. Lower, one notch each ; all edges level. 
Molars. Large, jagged. Canines long. 
Nose-leaf an isosceles triangle, apex rounded off, pubescent ; 
nostrils oblique. Nostril-lobes large: outside these, on each side, 
five warts, from each of which springs a long hair. LEars large, 
capacious, erect, with apertures directed forward, transversely wrm- 
kled inside. Skin of scalp so loose that fur will pull back, and leave 
merely bare skin over skull behind raised skin which connects inner 
edges of ear-bases. Interfemoral forked by calcanea, being stretched 
backward, shorter than extended foot. Teats lateral, flattened or 
compressed ; so that young holds in its mouth a broad projection, not 
a mere round dug. Lacteals large; exuded milk on pressure. No 
cranial ridge. Muscles of ferearm small, compared to those of Areti- 
beus carpolegus. Thighs, hardly any muscle. Bones, soft volars 
thin ; whole structure much more delicate and loose than in A. carpo- 
legus. Fur fluffy, loose, long, easily disarranged. Volar membrane 
extending along whole anterior edge of forearm, and, leaving only half 
thumb free, connects it beyond with first digit. Eyes large, bright.
