HABITAT.—India generally.
DESCRIPTION.—Muzzle broad and thick; upper lip overhanging the lower, marked by vertical wrinkles; ears large and quadrilateral; outer margin ending in a decided anti-tragus; tail thick; the lower part of the leg is free from the wing membrane, which however, is connected with the ankle by a strong fibrous band; fur dense, smoky or snuff brown above (or bluish black—Dobson); paler beneath.
SIZE.—Head and body about 2-1/10 inches; tail, 1-1/10. Jerdon gives length, 4¼ to 4-1/10; expanse, 13½; tail, 1¾.
This bat is common about Calcutta, frequenting ruins, dark places and hollow trees. It is allied to N. tenuis (Horsfield), and it is mentioned as inhabiting hollow trees in such numbers as to attract attention by the hissing noise from within, every available spot in the interior being occupied. A synonym of the genus is Dysopes.
[NO. 76. NYCTINOMUS TRAGATUS.]
HABITAT.—India generally.
DESCRIPTION.—This differs from the last in having the wing membrane from the ankles, and in the free portion of the tail being shorter; ears united at the base; tragus broad and rounded above, partially concealed by the large anti-tragus.
SIZE.—About the same as the last.
