Flying Insectivora. Mammals with the anterior limbs modified 
for flight by the elongation of the fore arm, and especially of four 
of the fingers, all of which are connected by a thin leathery mem- 
brane, which also includes the hind feet and the tail; humerus and 
femur not included in the common integument of the body ; teeth 
with enamel, the three sorts differentiated; mamme pectoral. The 
Bats are chiefly nocturnal in their habits, going into retirement in 
day-time, and hanging, head downward, by their hind claws. Most 
of them are insectivorous, a few in tropical regions feeding on fruits. 
About 400 species are known, chiefly of small size. The order is 
very sharply defined, but it has probably sprung from the same 
stock as the Insectivora. (yelp, hand; qrepov, fin.)
