NOCTILIONID^ 1. 
No facial cutaneous foliaceous appendages ; nostrils simple, opening at the extremity 
of the muzzle which is obliquely truncated and projects more or less beyond the lower 
lip. Tragus distinct, occasionally minute, usually well developed, and frequently 
expanded above. First phalanx of second digit of manus folded in repose on the 
dorsal surface of its metacarpal. Tail sometimes perforating the interfemoral 
membrane and appearing on its upper surface, or terminating in it; and sometimes 
strongly developed and extending far beyond the posterior border of the membrane. 
Teeth varying in number; generally a single pair of upper incisors separated from 
the canines and from each other in the middle line, but sometimes deciduous. 
No pubic teats. 
Distributed throughout tropical and subtropical regions of both hemispheres. 
This family is divided into two subfamilies, the Noctilioninoe and Molossince. 
Subfamily NOCTILIONINJS. 
Tail slender, perforating the interfemoral membrane and appearing on its upper 
surface or terminating in it; legs long, fibulae very slender; upper incisors weak. 
COLEURA. 
Coleura, Peters, MB. Ak. Berl. 1867, p. 479- 
Premaxillaries ossified. Muzzle broad, anteriorly pointed; forehead concave ; tragus 
longer than broad; no radio-metacarpal pouch; legs long ; fibulae very slender; tail 
short, last caudal vertebra projecting on the upper surface of the interfemoral 
membrane. Lower incisors and canines close together; upper incisors equally distant 
from each other and from the canines. 
Dentition ; i. g, c. j, pm. g, m. g = 32. 
Distribution .—East Africa, the Seychelles, and Southern Arabia. 
^ In 1898 Mr. T. S. Palmer (Proc. Biol. Soc. Washington, xii. 1898, p. 109) pointed out that the above 
family name has priority to Emballonuridse, Dobson, 1875, as it had been based by Gray (London Med. 
Repository, xv. 1821, 1st April, p. 299) on another genus of the family 50 years before Dobson wrote.
