into two cutting-edges, anterior edge sinuated. Lower rather 
smaller. 
Incisors. Upper, middle pair diverging slightly, entire, blunt, like 
human ; lateral minute, conical (or as a tubercle). Lower, edges 
forming a concavity between canines; lateral minute, truncated ; 
middle still smaller, visible only with glass in recent, but with the 
eye in prepared skull; conical truncated. (It is over these last the 
tongue is, of course, protruded.) 
Dental formula, milk teeth :—M. = C. = 16 <= 16. 
Molars. Upper hooked ; lower scarcely so. Canines excessively 
sharp, hooked backwards; upper largest. Incisors, upper middle 
broad, with one fine notch ; lateral hooked. 
Length to base of tail 22 inches, length to fork 2; expanse 123 ; 
radius 12, in others 2; thumb 3; last phalanges 2; index 24; car- 
pus, to tip, 3£; 4th digit 2}; muzzle to ear 2; knee to calcaneum 1 
(nearly); foot 2; calcaneum (minute) 75; ear, back 2, front 2. 
Tongue, protrusible beyond muzzle, 2 (it must have been more, ‘I 
think), narrows towards tip more suddenly than with Monophyllus 
redmanii; covered with reversed prickles, which are especially long 
and bristle-like, on the edges of tip: large and full, tip narrowed, 
thinner, hollowed; when shortened and contained within mouth, 
thrown into two rows of oblique strize or folds. 
In the young the tongue had the same striz, but only the tip 
was slightly extensible. 
Description. Nose-leaf pentagonal; central lobe reduced to a 
small blunt point on the upper angle; seen under the lens to be 
covered with fine white hairs. Nostrils round; external lobe two 
series of conspicuous confluent warts, centres depressed and punc- 
tured for hairs, one series on each side, leaving a space behind, cen- 
tral lobe free. Lower lip split, and on each side a notched triangular 
wart; upper lip fringed with hairs; but scarcely any beard. Ears 
ample, points rounded; tragus lanceolate acute. Tail short. Thumbs, 
legs, and toes very long, the latter regularly decreasing from hallux, 
which is longest. Forehead low. Muzzle very long; colour a soft 
chestnut-yellow, paler beneath, each hair at its base white; volars, 
ears, and nose-leaf pale black. No cranial ridge. Caudal vertebree 
5(?); intestine 14 inches long; stomach membranous, not reticu- 
lated, filled with a yellowish frothy pulp.

* It is in the eastern cave on this estate this pretty little Bat abounds, 
The entrance is in a wall of rock shrouded by a thicket. The in- 
terior of the cave not very extensive, and not thoroughly dark, I 
had, at first, no light; but the noise of innumerable wings, and the 
heaps of fruit and droppings with which the floor was covered, 
showed it was densely inhabited. I fired my gun towards where the 
sound was loudest; had just light enough to pick up what fell, and 
on taking it to the entrance, saw this interesting species for the first 
time. When the light arrived, I was surprised at their immense num-
