of wliicli there is no trace in the little-worn tooth of S. giganteus figured in the 
“F.A.S.” 
In plate VII., fig. 3, there is represented a slightly worn and partially broken 
last right lower true molar, collected by Mr. Tlieobald in the Potwar district, which 
agrees so closely with m. 3 of the specimen represented in fig, 4 of the same plate, 
that there seems every reason for referring it to the same species. This tooth has a 
length of 2 To, and a maximum width of To inches ; and it apparently indicates an 
animal still larger than that to which the specimen last described belonged : its size 
is indeed scarcely inferior to that of the corresponding tooth of Hippopotamus 
ampliihius. This tooth differs from m73 of the mandible represented in fig. 4 of the 
same plate merely by the outer portion {!)) of the talon extending somewhat behind 
the inner portion (r) ; thus causing the whole talon to be somewhat longer. 
Limh-hones . — In figures I and 2 of plate XII. of this volume there are figured 
the distal half of the left radius (fig. 1), and the third and fourth left metacarpals 
(fig. 2) which were obtained, in company with some broken bones, by-Mr. Theobald 
from the Siwaliks of the village of Niki in association with the cranium figured in 
plate IX. From the circumstance that the fracture of the radius is quite recent, and 
that the articular surfaces of the metacarpals and radius are perfectly uninjured, 
with their ridges sharp and distinct, there is no doubt that the whole skeleton was 
originally in juxta-position, and was broken up in the process of extraction. In the 
following table the dimensions of the figured bones are compared with those of the 
corresponding bones of a skeleton of a male of 8. scrofa in the Museum of the 
Royal College of Surgeons (No. 1765); viz.^ 
Fossil. 1 Recent. 
Length of third metacarijal 4-5 3-46 
Transverse diameter of ditto distally .... 1-19 0-86 
,, ,, ,, distal end of radius . . . 2-5 1-6 
The fossil bones agree so closely in general form with those of the existing 
sj^ecies, that they do not afford any characters of specific value. The skeleton of 
8. scrofa has a height of 31 inches at the shoulder; and taking the length of the 
third metacarpal as a modulus, the calculated height of the skeleton of the fossil 
would be 40 inches, or ten ‘ hands ’; — the height of a good-sized pony. The molars 
of the skull of the Niki pig (pi. IX.) are, however, by no means the largest which 
may probably be referred to that species, being about the size of those of the 
mandible represented in plate VII., fig. 4, in which the length of m. 1 is 2T6 inches. 
The larger corresponding tooth represented in fig. 3 of tlie same jDlate has a length 
of 2 ‘65 inches, and the calculated height of the skeleton of the individual to which 
that specimen belonged would be upwards of 49 inches, or 12^ Tiands’; — the height 
of a small horse. 
Specific distinctness and ajjinities . — As the result of the foregoing comparisons it 
appears that there is a very strong probability that the specimens described above 
are specifically distinct from 8. giganteus — a probability which will be almost a 
certainty if the mandible figured in plate XI. be correctly referred to that species.
