PHOENIX PARK. 
THE OWL-FACED BAT. 
May 1846. — A pretty and interesting little 
Bat came into my hands, a species of the curious 
genus Chilonycteris* It flew in at an open window 
at Phoenix Park in the evening, hut was not captured 
until after a very tedious pursuit, manifesting great 
agility on the wing. It looked much larger in flight 
* This closely resembles Ch. Madeayii (Gray), sent from Cuba by 
the zoologist whose name it bears. It differs, however, from that 
species in some of its admeasurements, and remarkably in colour. I 
therefore consider it distinct, and would thus describe it. 
Chilonycteris grisea, Mini. Expanse 1 11 inches. Length from nose 
to insertion of tail, 2 in. ; tail 1 in., of which ^ were free, above the 
membrane. Length of first finger, S^^gin. Ear, measured up the 
longer side, up the shorter, tragus (front side), 55 Muzzle 
to inner angle of eye, ; muzzle to ear, thigh, fg; leg, foot f*g 
nearly ; calcareum, ^in. Dental formula, M. ^ ; C. JEh ; I. | ; = 32 . 
Molars very jagged, with sharp points ; upper canines large ; upper 
incisors, middle pair, large, wedge-shaped, like the human incisors, 
with one notch ; lateral pair very small, pointed, leaning towards the 
middle pair ; lower incisors small, with two notches, the points equal 
in height. Muzzle dilated and truncated, in the manner of a hog’s, 
ending in four points, one above each nostril, and one on each side. 
Lower lip large, warty : below this there is, as it were, another lip, 
a thin projecting lamina. The skin at the sides of the head is a con- 
tinuation of the ear, reaching almost to the muzzle, inclosing, with 
the ear, a deep hollow, at the bottom of which is placed the eye, the 
fur diverging in front and below, like the facial feathers in Owls; 
the eyes are hidden in a front view : probably this structure is to 
converge the sound, not the r9,ys of light. The head is round, and 
prettily formed. The reproductive organs were inconspicuous, but 
it was a male. 
Colour of the upper parts brownish-grey ; of the under parts pale 
grey, silky ; the whole fur very soft, shorthand mole-like. The volar 
membranes black, much wrinkled. (Plate VI. fig. 1.)
