SIWALIK AND NARBADA PROBOSCIDIA. 
111—292 
APPENDIX. 
Since the above was in type, several specimens of Siwalik proboscidian remains have been received 
in the Indian Museum, some of which require a short notice, and have engendered the necessity 
of issuing an additional plate (XXXV A) . 
Dinotherium sindibnse, nobis. 
Of this species, a single ramus of the mandible, collected by Mr. Wynne in the Siwaliks of 
the Kohat District, has been received by the Indian Museum. The crowns of the molars in this 
jaw have, unfortunately, all been broken off, but the size and form of the jaw agree precisely with 
those of the Sind specimen (Plate XXXI, fig. 4), and confirm the conclusions deduced therefrom. 
Mastodon pandionis. Falconer. 
Mr. Theobald has remitted to the Indian Museum a magnificent specimen of the palate of this 
species, from Nila in the Punjab, showing the penultimate and last true molars of either side. In 
Plate XXXY A, the two teeth of the left side have been figured. These two teeth are very 
important, as completing our knowledge of the true molar dentition of this species ; no specimen 
of the penultimate upper molar was known to me when describing the dentition in detail, and only 
one bad specimen of the last molar, alluded to on page 218. I shall not describe the new teeth in 
detail, but merely mention their leading features. 
The penultimate tooth is considerably worn, carries three transverse ridges, and may have had 
a small hind-talon. The last molar is only slightly worn, and carries four ridges and an anterior 
talon : the ridges of this tooth dimmish in size gradually from the first to the last. A large 
quantity of cement is present in the valleys, which are completely blocked by accessory columns or 
tubercles. The ridges when worn present irregularly shaped, and depressed surfaces of dentine. 
In all the above characters, these two teeth agree with the molars of M. pandionis described 
above, and unquestionably belong to that species ; they show that the species was a true Trilophodon. 
In the palate, the two teeth of either side converge to a very small extent anteriorly : their 
plane of wear slopes very considerably from the outer to the inner side. The dimensions of the 
specimen are as follows : —
