external enamel fold, and two or more smaller inner folds, wliicli persist till the 
crown is qnite worn down. These characters agree, therefore, perfectly with the 
characters of oirr Siwalik specimens, and I can have no doubt but that the latter 
belong to that genus; I have compared these molars with the teeth of B. mma- 
trensis, and find that they can only be distinguished in form from the latter by 
the greater depth of the external fold, and by the smaller size of the first internal 
fold; the fossil molars are in one specimen slightly smaller, and in the other 
slightly larger, than those of the recent species ; the fossil mandible is, however, 
narrower and slenderer, the incisors much smaller, and there are other differences 
in the form of the two mandibles which are quite sufficient to specifically distin¬ 
guish the two forms; these differences will be pointed out on a subsequent 
occasion. I shall hope to give a figure of the fossil. The fossil teeth ai’e larger 
than those of any of the other species with which I have been able to compare 
them: should they belong to a now species, as I think is probably the case, 
I shall proijose to call this species It. sivalemis. 
It may not be out of place here to observe that among Falconer’s undesoribed 
Siwalik Mammalia, there was indicated a new genus under the name of TypModun. 
The name only of this genus occurs in the Introduction to the “ Fauna Antiqua 
Sivalensis” (Pal. Mem., p. 2.3), and from the contents it is evident that this genus 
belonged cither to the Podents or Insectivores ; from the name Ti/pModon I think 
that the genus must have belonged to the former, .since the name appears to be so 
evidently derived from Sj^aUhti typhlm. This being so, and since our now 
Bhizomys belongs to the Spaladnce, I think it not at all improbable that Falconer’s 
TypModon was founded on the same Bhizomys. The Introduction in que.stion was 
published in 1844, and a great part of it was written much earlier in India; it 
is, therefore, not improbable that Falconer was unacquainted at the time of 
wi’iting with the genus Bhizomys, which was made in 1830,’ and that finding a 
Podent allied to, but distinct from, Spalax, ho made a new genus for its 
reception. 
The genus Bhizomys being confined at the present time to Asia, it was only to 
bo expected that fossil representatives should be di.scovored in the pliocene of 
that continent; living species are found in India in the Khasi Hills, and the 
Sikim Terai. (Jerdon.) I beHove that no fossil species of the genus has hitherto 
been described. An allied genus {Myospalax") has been formed for the 
reception of the so-called “ Quettah mole;” I cannot, however, find that this 
genus has been described; and I cannot, therefore, say in what respects its 
dentition differs from that' of Bhizomys and Spalax. The genus is not intro¬ 
duced into Mr. Alston’s synopsis. 
CAPNIVOPA. 
The remains of Carnivora are of somewhat rare occurrence in the Siwaliks, 
and therefore almost every specimen obtained is worthy of notice.
