ARTICLE XIX.--DESCRIPTION OF A NEW VESPERTILIONINE BAT FROM YUCATAN.

By J.A. ALLEN.

In a small collection of mammals recently sent by Dr. G.F. Gaumer from
Izamal, Yucatan, to this Museum for identification, is a single
specimen of a species of _Adelonycteris_, which appears to be
undescribed. It may be called

ADELONYCTERIS GAUMERI, sp. nov.

Above dark brown, with an olivaceous wash, the fur being
uniform dark brown to the base tipped with a slight tinge of
olivaceous, the extreme tip slightly grayish in certain
lights; below much lighter, the fur being dark brown basally
and broadly tipped with pale buffy gray; ears and membranes
black, naked, and with no trace of a whitish border. Ears of
medium size, rather thin, evenly convex on the front border,
slightly hollowed on the posterior border below the rounded
posteriorly directed tip; tragus long and rather narrow,
pointed, equal to half the height of the ear. Face
semi-nude, about as in _A. fusca_.

_Measurements._--"Length, 95 mm.; expanse, 286; wing, 124;
tail, 40";[1] ear, 21; tragus, 11; fore arm, 39; thumb, 7;
3d digit, 79 = phal. i, 37, phal. ii, 24; phal. iii, 11;
phal. iv, 7; tibia, 70; foot, 8.

specimen; the rest are from the dry skin.]

_Skull._--Similar in a general way to that of _A. fusca_,
but about one-
