III. GENUS HEQ@ESTES (supra, p. 244). 
Remains of Carnivores which have been referred to this genus 
occur in the Miocene and Upper Eocene (Oligocene) strata of 
Europe; but many of these present characters intermediate 
between the existing members of the genus and Viverra, so 
that it is frequently impossible to say to which of the two they 
should be assigned. For instance, the above-mentioned 
Viverra minima has been referred by one writer to Hlerfesies, 
while some specimens referable to 4. /emanensis have been 
described as Viverra. It would thus appear that the two 
genera had a common origin; and it may be added that 
through an extinct Miocene and Upper Eocene genus known 
as Cynodictis they both seem intimately connected with the an- 
cestors of the modern Dogs and Foxes (Canide). 
One of the best known species is the large Hferpestes leman- 
ensis from the Lower Miocene deposits of the south of France, 
with which the so-called Viverra antigua, and perhaps #. 
priscus, as well as a German form, appear to be identical. The 
skull is stated to approximate to Viverra in possessing an ali- 
sphenoid canal. A second Lower Miocene species (Z&. primea- 
vus) is distinguished by the great relative length of the last lower 
pre-molar tooth, while in the Middle Miocene beds of Grive- 
St.-Alban, France, the genus is represented by yet another 
species known as Lerfestes crassus. 
IV. GENUS PROGENETTA. 
Progenetta, Depéret, Archiv. Mus. Lyon, vol. v. p. 34 (1892). 
This genus is represented only by a single species (P. z7- 
certa) of the size of a small Leopard from the Middle Miocene 
dep:sits of France, and is chiefly distinguished by details in 
the structure of the teeth, into the consideration of which it 
would be quite out of place to enter in a work of the present 
nature.
