VESPERTILIO INXESI. 
121 
Vespertilionine Section. 
Nostrils simple, opening by crescentic orifices at the end of the snout. Forehead 
not grooved. Ears generally of moderate size. 
VESPERTILIO. 
Vespertilio, Linn. Syst. Nat. 10, i. 1758, p. 31 {nec Dobson). 
llody thick and heavy; head broad and flat; muzzle obtuse, vrith glandular 
eminences between the eyes. Ears separate, short, broad, triangular, obtusely pointed ; 
tragus usually short and incurved, with the outer margin more or less convex and the 
inner concave or straight. Legs short; a postcalcaneal lobe generally present; feet 
short and broad. 
Dentition : i. |^, c. y, pm. y, m. |- = 32. 
Outer upper incisors well developed, or if small, distinct. 
Almost cosmopolitan in its distribution, but most common in temperate and 
subtropical regions of the Eastern Hemisphere ; some species, however, extend to thd 
Western Hemisphere. 
In text-books the next genus {Pipistrellus) will be found linked to Vespertilio 
(= Vesperus of Dobson) as a subgenus of the very large and unwieldy genus Vesperuqo ; 
but by most systematic workers it is now considered more convenient to re^wd the 
two as distinct genera, although the known characters which separate them are 
slight. As regards the species of the two genera which are found in Egypt, they are 
clearly separated by the absence or presence of a bone in the penis ; this peculiarity, 
however, has not yet been investigated in the large majority of the species of the world,' 
so it cannot be here given as a character of universal generic value.
