Species 1 : Listeiodon PENTAPOTAMiiE (Falconer). 
Syn. Tapirus pentapotamice^ Falconer. 
History . — Tlie history of the species has been already given in the first volume.^ 
Upper molars. — In figures 13 and 17 of plate VIII. the two original specimens 
on which this species is founded are refigured^ : both teeth belong to the right true 
molar series ; and the first (fig. 13), which was obtained by Mr. Theobald from the 
Siwaliks of the Punjab, is almost unworn, and, from its size, may be regarded as 
m. 1 . The second (fig. 17), which was obtained by Messrs. Garnett and Trotter from 
the Siwaliks of Kushalghar, below Attock, is partially worn, and may be regarded 
as m. 2 . In fig. 15 there is represented a much worn and partly broken second left 
upper molar, which is slightly wider than the specimen represented in fig. 17 : this 
tooth belonged to the same individual as the specimens represented in figs. 14 and 16, 
and, together with the corresponding tooth of the opposite side, was collected by 
Mr. Theobald in the Siwaliks of Niki, Punjab : it is in a well-worn condition. The 
tooth represented in fig. 16 is the third left upper true molar, in a well-worn 
condition, wanting the postero-internal angle. In fig. 15a there is represented the 
hinder portion of the third right upper true molar, in an unworn condition, probably 
belonging to the same individual as the specimen represented in fig. 17. In fig. 14 
there is represented the much-worn first right upper incisor belonging to the same 
individuals as figs. 15, 16. In the following table the dimensions of the above- 
mentioned teeth are compared with those of a specimen of the right maxilla of 
Listriodon splendens in the Lyons Museum, the measurements being taken from a 
plaster cast in the British Museum (No. 40,959) : —

The dimensions of the Indian teeth are such that all the specimens may, at 
least provisionally, be referred to the same species ; and their resemblance to the 
European form is so close that there can be no doubt of their belonging to the genus 
Listriodon. In size the Indian teeth are rather larger than those of L. splendens.^ but 
the difference in this respect is so slight that it cannot be regarded as of any specific 
value. In the upper molar of L. splendens figured by Gervais® the cingulum is more 
distinctly developed on the outer surface than in the Indian teeth ; and the same
