SECTION VII. MEGALOTIS. 
THE FENNECS OR ZERDAS. 
Wirnovt adozting Illiger’s reasons, we detach the 
present group, under the denomination he applied to 
the Zerda, from the other diurnal canines, and more 
particularly from jackals and foxes, with which they 
have been confounded, and place them immediately 
after that of Cynalopex, with which it is nearly 
allied. When the long brush-tailed species shall 
have been studied with more care, there is little 
doubt but that others will likewise require to be 
separated. The group now under review is formed, 
because the species that have been attentively exa- 
mined have the eyes with a circular disk, and there- 
fore belong to the diurnal tribe ; they have only six 
mamme,? and form the last subdivision of those 
found in the eastern hemisphere. Although, by the 
increased proportions of the ears, several of the 
species before described, and most of the smaller 
African canines, approximate Megalotis, they are 
destitute of the following characters, by which 
alone the Zerdas are distinguished :—They have the 
ears disproportionately developed, and the folds at 
the edges double or treble. Such a structure cannot 
well be given without a corresponding effect ; and
