MOLAU TEETH AND OTHER REMAINS OE MAMMALIA. 
Order: CARNIVORA. 
Genus Amphicyon, Lartet. 
Amphicton pal^indicus, n. sp. Falc. et nobis. Plate 7, figs. 5, 8, 12. 
This genus of extinct Subursoid mammalia^ distinguished from their living 
congeners by having been furnished with three instead of two tubercular molars 
in the upper jaw, has hitherto been definitely known only from the miocene strata 
of Europe, where four well-marked forms have been determined, viz.^ A. major, 
A. minor, A. dominans, Meyer, and A. lielveticus, Pietet, and from the Tertiaries 
of Nebraska, from which two species, A. vetus and A. gracilis, have been described 
by Professor Leidy. 
No specimens of the genus were known to Dr. Ealconer at the time of pub-- 
lishing the “ Eauna Antiqua Sivalensis” ; subsequently, however, among a collec- 
tion of mammalian remains sent to him for determination by Dr. Oldham from 
tertiary strata at Kushalghar below Attock, Dr. Ealconer {see “ Palceontological 
Memoirsj^ vol. I, p>- 1^16) discovered a tubercular upper molar tooth, which he said 
must have belonged to a carnivorous animal, as large as the Folar Bear, and 
allied to the Ampliioyon. This tooth was, with the other specimens from the same 
locality, subsequently returned to the Indian Museum, where it now remains ; 
for the first time I give a figure and description of the specimen {Bl. IV, jig. 5). 
N o specific name ajopears in the account of the specimen in the “ Palaeontological 
Memoirs,” but in a manuscript of Dr. Ealconer’s on this specimen given to me 
by Dr. Oldham, the species is named A. palceindicus. It will be observed that 
in its general form the tooth corresponds with that of the European forms of the 
genus, but that it presents certain modifications of detail by which it is distin- 
guished : these modifications, however, do not appear to me to justify the placing 
of the specimen in a separate genus or sub-genus, and I have therefore retained 
it under Ampliicyon ; it is, however, I think, doubtful from Ealconer’s remark on 
the specimen, as being “ nearly allied to Ampliicyonj’ whether he himself intended 
to place it in that genus. 
In addition to the above specimen, we have in the Indian Museum another 
tooth of Ampliicyon {Bl. lY,jig8. 8, 12) : this second specimen is the “carnassial” 
tooth of the lower jaw — it is of such a size that it seems too large to have been the 
lower molar of the same species to which the upper molar belonged ; to prevent, 
however, the unnecessary multiplication of species, I have, for the present at all 
events, referred it to the same species as the former specimen : this tooth was 
brought by Mr. Medlicott from the Siwalik strata of Nurpur. 
Reverting to the upper molar, we find that the specimen is the second true 
molar of the right maxilla ; it is quite perfect, and belonged to an adolescent 
animal, as none of the points of the lobes have been touched by wear. 
The outline of the crown is nearly in the form of an isosceles triangle, of which 
the outer border forms the base : the apex of the triangle is rounded off. The
