short and edentulous. Those molars in which the median cleft is 

 most marked approximate very closely to certain examples of those 

 of M. latidens, of which the present species may be regarded as the 

 descendant 1 .

41925. A third right upper milk-molar, provisionally referred to 

 {Fig.) this species ; from the Pliocene near Shanghai, China. 

 This specimen is the type of Stegodon sinensis, and is de- 

 scribed and figured under that name by Owen in the 

 Quart. Journ. Geol. Soc. vol. xxvi. p. 417, pi. xxvii. ; it 

 is also figured and provisionally referred to the present 

 species by the writer, in the ' Palaeontologia Indica,' ser. 10, 

 vol. i. p. 257, pi. xlv. fig. 2. There are four complete 

 ridges, and a large anterior talon, which is reckoned by 

 Owen as a fifth ridge. The median longitudinal cleft is 

 very indistinct. 



Presented by Prof. Sir JR. Owen, K.C.B., 1870. 



M. 3421-2. Cast of the fourth left upper milk-molar in a fragment 

 of the maxilla, together with that of the germ of pm. 4 which 

 was imbedded in the maxilla, provisionally referred to this 

 species. The originals were obtained from the Siwaliks 

 of Asnot, Punjab, and are preserved in the Indian ITuseum 

 (No. A 64) ; they are figured by the present writer, op. cit. 

 pi. xxxvii. figs. 6, 8, as Mastodon latidens. The milk- 

 molar agrees, however, precisely with the teeth of the 

 next specimen (which was referred by Palconer to the 

 present species) 4 ; it differs from the teeth of M. latidens in 

 the deep grooving of the enamel, and the greater number 

 of cusps on the ridges ; the latter are five in number, 

 the fifth being smaller than the others 5 . There is a slight 

 median cleft on the fourth ridge, which is wanting in 

 No. 7388. Made in the Museum, 1886. 



1 M. latidens occurs in the Lower Siwaliks of Sind, where E. clifti is unknown.

4 The tooth figured in the ' Palaeontologia Indica,' ser. 10, vol. i. pi. xlv. fig. 1 

 a 8 mm. 4 i s probably m. l ; its ridges may be reckoned as seven, and it agrees 

 in general characters with mm. 4 f the present specimen. 



6 When referring this tooth to M. latidens the fifth ridge was reckoned as a 

 large talon.
