1762 CARNIVORA. 
by the larger size of the talon of the carnassial, and the 
lesser vertical depth of the horizontal ramus. MM. elongata, 
P. Gervais’, of the Lower Pliocene of Montpellier, is of 
considerably smaller size, but agrees in having a relatively 
long and basin-shaped talon to the carnassial; this talon: 
is, however, proportionately narrower, and the inner cusp 
of the blade is larger and placed more posteriorly, causing 
the ‘‘cusp-line” to be more oblique. The mandible 
figured by P. Gervais * under the name of M. minuta is at 
once distinguished by its diminutive size. The mandible 
of M. ardea*, Bravard, agrees very closely in size, but the 
talon of the carnassial appears relatively smaller; the 
inner aspect of this tooth is not figured. MM. taxodon, 
P. Gervais *, has the talon of the carnassial still larger 
and more distinctly basin-shaped ; and it is highly probable 
that this form should really be referred to a new genus 
allied to Meles. M. incerta’, Lartet, of Sansan, even if 
it really belong to the present genus, is distinguished by 
its greatly superior size. The so-called M. hydrocyon, P. 
Gervais ° (Hydrocyon sansanensis, Lart.), is slightly larger, 
and the ramus of the mandible relatively deeper—its depth 
exceeding, instead of being less than, the length of the 
carnassial ; the inner border of the crown of that tooth is 
also higher. The insufficiently described WZ. zorilloides’, 
Lartet, from Sansan, seems to be of smaller dimensions. 
A species said to be allied to the Martens has been de- 
‘ scribed by Filhol®, from the Quercy phosphorites, under 
the name of J. felina, which is sufficiently distinguished 
from the present specimen by the absence of an inner 
cusp to the lower carnassial. MW. angustifrons and M. 
sectoria, P. Gervais, are considerably smaller ; and it does 
not appear that any others of the described fossil forms 
approach the Siwalik jaw. The lower carnassial of the 
allied genus Plesictis is distinguished by the much larger 
development of the inner cusp. 
It thus seems that the present specimen indicates the 
existence of a species of Mustela in the Siwaliks closely
