Punjab. The specimen contains the four anterior teeth of the molar series, which have 
only just come into wear; only a short notice is here given of these teeth, as they will 
subsequently be figured and fully described. 
The first premolar is very small; it is inserted by a single fang ; the three succeeding teeth 
are inserted by distinct fangs, and their crowns are consequently extremely short; their 
grinding surfaces are oblong, their antero-posterior diameter being the longer of the two; 
the second tooth is elongated. The larger teeth consist of six lobes, of which the outer and 
middle pairs are the larger, the latter pair being concave externally; the antero-internal lobe 
is placed between the two median lobes, and is entirely unconnected with them ; the postero¬ 
internal lobe is connected by a narrow bridge with the postero-median lobe; the medial 
enamel infolds ai - e deeply crenulated, and all the hollows are filled with cement; the length 
of the three large teeth is 3'05 inches; the length of the penultimate tooth is T25 inches, 
and its breadth 09 inch. 
The teeth approach nearest to those of Hippoiherinm, but are distinguished among 
other characters by their elongated crowns, and by being inserted by distinct fangs as soon as 
they are protruded ; in the latter character they agree with the American Protohippus and 
Mery chippies, but are distinguished by having the antero-internal column detached from the 
antero-median column. 
The completeness of the median columns distinguishes these teeth from those of Anchi- 
therium and its kindred. 
The generic name is derived from the name of the beds in which the specimen was 
found, and the specific name is given after Mr. Theobald, the discoverer of this and so many 
other Siwalik fossils. 
An examination of the remains of Siwalik Eqtiidre in the Indian Museum has convinced 
me that, besides the above new genus, there are two species of true Equus from these depo¬ 
sits—namely, E. sivalensis, and a new species; and that there are also two species of Hippo- 
therium, —namely, IT. antilopinum, and a larger new species. Two detached middle molars of 
the latter species are figured by H. von Meyer in the fifteenth volume of the German Palseonto- 
graphica, under the name of Equus primiqenhus (=Hippotherium grocile) ; a more com¬ 
plete series of the dentition of this species enables me to state that it is certainly distinct 
from the European species, which must consequently be expunged from the lists of Indian 
fossils. A memoir on the dentition of all the Indian fossil Equidce, in which the new 
species will receive names, will subsequently appear. 
ICTITHERITTM SlVALENSE, n. Sp., nobis. 
The above genus of Viverroid carnivores was first made known to science by 
M. Gaudry, who determined two species from the upper miocene of Attica; two fragments 
of the mandible of a Viverroid carnivore, lately sent down by Mr. Theobald from the 
Siwaliks of the Panjab, appear to agree very closely with the lower jaw of the European 
I. robustum, and I have accordingly referred them to that genus with the specific name of 
sivalense. 
The two fragments are respectively from the right and left sides, and probably belonged 
to the same individual; the larger of the two comprehends the hinder half of the left 
ramus, lacking the condyle and the coronoid and angular processes ; it shews the sectorial 
molar, the socket of the second molar, and the greater part of the ultimate premolar; the 
smaller fragment comprises a portion of the middle of the right ramus shewing the two 
last premolars.
