72 MR. W. OSBURN ON THE BATS OF JAMAICA. [Jan. 24 
where (deciduous) canine will be, and two a little behind, near po- 
sition of lesser molars. Three on each side, lower jaw, in same 
situations.” 
7. Mormooprs BLAINVILLII, Leach *. 
Expanse 123 inches; muzzle to tail 21; tail 14, free 2; forearm 
132; first digit 24; fourth digit 2}; thigh }; tibia to caleaneum 73 ; 
calcaneum 2; foot 2. Length of interfemoral 14 ; beyond tip of 
tail, when expanded,  (?). 
Muzzle flat, depressed ; skin of sides of face connects muzzle with 
ears by a series of folds concealed by silky moustache. Upper lip 
obsolete in front, foliated behind with a single indent. Lower lip 
expanded into a thin broad cordate lamina, with a short foot-stalk 
between the lobes warted. Below this, and attached perpendicularly 
and transversely to its under surface, two thin, membranous, but 
broad lobes, like clerical bands. These are carried backwards, with 
sinuous folds. Thirdly, below this last, and attached to their under 
surface, two thin folds of skin, one to the under surface of each 
band. These are carried back on their respective sides, with one 
deep indentation near centre of their course, then, continuing back- 
wards and upwards till they reach the fold which connects lower ear 
with muzzle. 
Ears united with skin at sides of face, so as to contain the eye. 
Eyes about size of a pin’s head, bright, and both at same time visible 
on front view. Ears somewhat lunate, or perhaps rather the shape 
of some bivalve shells; tips brought forward and doubled on them- 
selves before meeting over forehead. The external ear is furred, and 
the long silky fur of head extends over forehead, meeting the long 
moustache. The head thus appears disproportionately large, and the 
ears imbedded or plunged in it, so that only a narrow rim of mem- 
brane is visible above the fur externally. 
Tongue fleshy ; when in mouth, furrowed with about six trans- 
verse plicz. 
Dental formula, M. = (Pin OF = MF s=34 (?). 
Molars jagged (there appear three lesser molars in lower jaw). 
Incisors, upper, middle, one notch ; lateral minute, leaning towards 
them. Lower level; each two notches. 
Intestine 4 inches. Stomach empty. 
Volar membrane semitransparent, and tissue so thin it dried 
almost before I had finished preparing the specimen ; much wrin- 
kled, between elbow and hand, into angular plice like shagreen. 
Nerves of interfemoral very beautiful when held against light ; one 
central in line of tail, giving off at right angles pairs of branches 
like a pinnate leaf. Fur bright chestnut, above rather paler ; very 
long, silky, and soft. Round the shoulders it is longer, so as to 
form a narrow frill longer than rest.
