The characters of the head, ears, nose-leaf, and even the gland- 
like swelling on the front of the thorax, are as in A. centurio. 
The warts on the lower lip are six in numl)er instead of seven as 
in that species. In comparison with the figure given by Dobson 
they are not well defined. The markings of the wing membranes 
are as in other sfjecies of Stenodermatidae, excepting that the 
inesopatagium is furnished with eleven long, nearly vertically 
disposed muscle-lines which converge to a single point near the 
forearm. 
The terminal cartilages are filiform. The pigment is absent in 
the first and second digital interspaces. 
The gland-mass at the other side of the nose-leaf is raised on a 
skin fold as in Ectophylla. The glands, three in number, are 
lodged well up on the face and occupy a groove between the eye 
and the nose-leaf. 
Teeth. Peters in his descrij)tion of Ametrida centurio describes 
a small "basal cusp" on the maxillary central incisor, and a 
bilobed minute lateral incisor ; the lower premolars are not of the 
same form and size, the second being smaller than the first. 
These characters are not found in A. minor, in which species the 
superior lateral incisor is nearly half the length of the central. 
Dobson gives a description to which the teeth of the new species 
conform for the most part, but I find the intervals between the 
maxillary centrals too great to accept the statement that the teeth 
fill up by their bases the wide space between the canines. I infer 
that the London and Leyden specimens are not so much alike as 
are the London and the Boston examples, so far as the characters 
of the teeth are concerned. 
Rugae two in number ; the rest of the hard palate being occu- 
pied with minute mammilations as in Sphaeronycteris. Fur 
above including the iiead is of a (lull white ; the hair is long, the 
extreme ti[) and base having a delicate shade of brown. IJeneath, 
a conspicuous patch pure white in color lies on the ventral as]>ect 
of each shoulder. A covering of short hair is seen on the wing 
membrane extending from the trunk to the distal third of the 
liumerns and almost to th.e knee. This distribution is notewortiiy 
from the lact that it. is iiotMistinctive fi'om that of the back of the 
trunk, but the hair in the region just named extends upon that of 
the wing membrane so that no limitation between the trunk and 
the meml)rane can be detected. The fleshy part of the forearm
