of the Punjab, lias been already referred to by me in the “ Records,” as noticed 
above. That tooth carries seven ridges, each of which has only a small number of 
cusps, and exhibits a slight trace of a mesial cleft, with the plane of wear sloping 
from the inner to the outer side. It seems from these two specimens that the 
lower molars of S. cliftii carry a smaller number of cusps tlian the upper. 
Conclusion. — The skull and complete mandible of S. cliftii are unfortunately 
still unknown, and \re must, therefore, depend entirely on the teeth for its specific 
characters. The whole of the upper molar series, with the exception of the first 
milk-molar, are now known, while of the lower molars only the last is known. The 
ridge-formula of the species may probably be represented as follows -

History.— The first mention that I can find -of Stegodon hombifrons occurs in 
the Introduction to the “ Pauna Antiqua Sivalensis,”^ where the name only is 
mentioned. Purther on in the same w'ork^ mention is made of the cranium of the 
species, and some of the characters of the molars are pointed out. The molars are 
said to differ from those, of S. insignis [vide infra) in having broader and less 
elevated ridges, and more open valleys, and by the number of ridges being fewer, 
though greater than in S, cliftii. In Plates XXIXA & B of the same work 
various specimens of the molars are figured, showing that the last upper milk- 
molar had six ridges, and the corresponding lower tooth either five or six ridges, 
Avhile other specimens of the “ intermediate” molars had seven ridges, and the 
last lower molar never carried more than nine ridges. In the “ Records”^ I alluded to 
a six-ridged tooth, which I then thought to be the first upper true molar of S. bombi- 
frons, but which, as noticed above, I now find probably belongs to S. cliftii; the cor- 
responding tooth referred to on the same page of the “ Records” as belonging to the 
so-called S. sinensis of Professor Owen I now find belongs to the present species. 
Molar series. — With these preliminary remarks, I wiU now consider in serial 
order such of the molar teeth of this species as are at present known to me. 
First milh-^molars. — Of the first milk-molar, either of the upper or lower jaw, 
I can find no specimen. 
Second upper milk-molar. — Of the second upper milk-molar I likewise cannot 
find any specimen.
