PROBOSCIDIA. 
Mastodon (Teilophodon) sp. nov. ? 
No species of Trilopliodont Mastodon lias hitherto been known from the Siwaliks, 
though one species— M. pandionis —has been found in the Deccan. I have now to announce 
the presence of a species in the Siwaliks ; this species is known by two lower molar teeth, 
one of which is the last milk-molar, and the other is the penultimate true molar. Both 
specimens were collected last year by Mr. Theobald from the Siwaliks of the Punjab. 
Each of these teeth carries three transverse ridges and a fore and aft talon; the 
presence of only three ridges on their teeth shews that they cannot belong to either of 
the two Indian Tetralopliodont Mastodons [M. latidens and M. perimensis) or to the 
aberrant Pentalophodont ili. sivalensis; in the first of these groups only the very small 
second milk-molar is trilopliodont, while in the second group only the first, and perhaps the 
second, milk-molars are trilopliodont. 
Both the present specimens beloug to the wide-toothed Mastodons; the ridges are 
divided by an autero-posterior median valley; the first two pairs of columns are placed in 
the same transverse line, but the third pair are placed somewhat uasymmetrically; there is 
a large quantity of cement in the valleys, which of itself would be a sufficient distinction 
from the other Indian species : the transverse valleys are fairly open. The length of the 
larger specimen is 6'8 inches, and its breadth 37 inches: the length of the last milk, 
molar is 4T inches, and its breadth 2'4 inches. 
The teeth have .not the complex crowns of the Trilopliodont Mastodon pandionis; 
it is therefore quite clear that they are distinct from all other Indian species of the genus ; 
I believe they are also distinct from any European species. If the latter should prove 
to be the case, I should propose to call the present species by the name of Mastodon 
(TrilopTiodon) Falconeri in honor of the describer of the many other forms of extinct 
Indian Proboscidia. 
CARNIVORA. 
PsEUDjEiiUBUs Sivalensis, n. sp. 
Mr. Theobald’s Siwalik collection from the Punjab contains one-half of a lower jaw of 
a Feline animal with four pre-molars which consequently belongs to this genus; the 
specimen belonged to an animal of about the size ol a small Leopard. The carnassial tooth 
is of the normal Feline typo: only two other specimens of the genus Pseudtslwncs are 
known, one from the Miocene of Sansans, and the other from the Pliocene of Nebraska. 
Both species are distinguished by their size from the present specimen. The dimensions of 
the specimen are as follows:—■ 
Length of jaw (broken) ... .. 3‘5 I Thickness .. .. .. ‘5 
Depth .. .. .. ' '8 1 Length of alveolus of canine .. ‘75 
Amphicyon Palaiindicits, nobis. 
The only remains of this species hitherto known are an upper tubercular molar, and 
a lower carnassial, one from Kushalghar, and the other from Nurpur. These specimens 
are figured on PL 7 of “ Indian Tertiary and Post-Tertiary Vertehrata.”* Mr. Blanford 
has sent from Sind the anterior half of a right lower carnassial, which exactly corre¬ 
sponds with the Nurpur specimen, and which shows that the species extended its range 
into the Sind area.
