DINOTHERIIDiE. 11 



The folloiving specimens, the originals of which are from Eppelsheim, 

 belong either to the present species or to Mastodon longirostris ; 

 it is said that Kaup was inclined to refer them to the former. 



1544. Cast of the imperfect right femur. Purchased. Before 1836. 



M. 2948-9. Cast of a calcaneum and unciform. 



Purchased. Before 1836. 



Dinotherium indicum, Falconer l . 



Including: — Dinotherium pentapotamice, Lydekker 2 {ex Falconer). 

 Syn. Antoletherium, Falconer 3 . 



Since the difference in size between D. indicum and D. pentapotamice 

 is not greater than the variation obtaining in the forms included 

 under the head of D. giganteum, the two are provisionally classed 

 together. Both have been identified by Weinsheimer 4 with the 

 European species ; but there appear to be slight differences 5 in the 

 teeth, which may be of specific value. Thus pm. 3 and p m . 3 do not 

 agree exactly with those of the latter species, while in the mandible 

 (' Palseontologia Indica,' ser. 10, vol. i. pis. xxix., xxx.) the low 

 longitudinal bridge connecting the transverse ridges of the true 

 molars is relatively more developed, so that the worn first and 

 second ridges of mTT are connected by a bridge of dentine before 

 those of pm. 4 are so connected, while the dentition islet of the 

 third ridge of mTI is of a regular elliptic form. One specimen 

 seems, moreover, to indicate a characteristic difference in the form 

 of the incisors 6 .

6 The opportunity of comparing the figures of the Indian specimens given in 

 the ' Palseontologia Indica,' op. cit., with the European ones, has shown the 

 writer that many of the differences there indicated are not of more than indi- 

 vidual value. 



6 Falconer (see ' Palaeontological Memoirs,' vol. i. p. 408) observes : " In 



corroboration of this view [i. e. the specific distinctness of the Indian Dinothe- 

 rium] it deserves to be stated that, of the numerous Proboscidea discovered in 

 India, we have found that all the forms are specifically distinct from those 

 which occur in Europe." The subsequent discovery of M. angustidens on the 

 north-west frontier is hardly an exception to this generalization.
