MAMMALIA. 
Genus Molossus . — The Molossus are animals with a large head, 
thick blubber-lips, more or less fringed, and with the interfemoral 
membrane only reaching to one half of the tail. Their tout ensemble 
is simply hideous. They inhabit the hot and temperate regions of 
the two continents. Eight or nine species are known, only one 
of which has been observed in Europe ; the largest is the Collared 
Molossus, which inhabits Borneo and the kingdom of Siam, and 
the span of its wings is twenty-six inches. 
Genus Nyeteris . — The nose in this genus is pierced by a cavity 
in which the nasal-leaf is concealed. This leaf, therefore, exists, 
though it is not visible externally. The tail is of medium size, 
and supports the interfemoral membrane throughout its length. 
These creatures inhabit different parts of Africa, such as Egypt, 
Sennaar, and Senegal, and are also found in Java. Up to the 
present time, only three species have been discovered. They 
measure from eight to ten inches across the wings. 
Genus Bhinolophus . — The animals belonging to this genus are 
distinctly characterised by the presence and the arrangement of 
the nasal leaf, which is composed of two parts, somewhat similar 
to that of the Yampires: one has the form of a lance-head, and 
is placed at the root of the forehead, the other margins the upper 
lip, and is more or less in the shape of a horse- shoe ; the nostrils 
open between these two membranes. The ears and tail are of 
medium size ; the interfemoral membrane entirely embraces the 
latter. At the flanks two glands are found which have the 
appearance of mammae, and secrete an odoriferous substance. 
With regard to size, the Bhinolophus differs but little from the 
Yespertilio; it has a long abundant fur, generally of a light 
shade, and which is sometimes remarkably handsome. 
These Cheiroptera are widely spread in the Old World, in 
Europe, Africa, Asia, and the islands of Sunda ; no species are 
found in America. They live in numerous bands during the 
greater part of the year. When the females are with young, they 
separate themselves from the males, to bring forth and rear their 
progeny. When the latter are capable of supplying their own 
wants, the mothers cease to attend them, and return to live in 
the society of the males. 
The most considerable species of the genus is the Giant 
Bhinolophus, which inhabits Java and the Moluccas; it measures
