Karnul district, Madras. Similar specimens are figured 



by the writer in the ' Palaeontologia Indica,' ser. 10, vol. iv. 



pi. xi. figs. 5, 6. Presented by the Director 



of the Geological Survey of India, 1886. 



Family POEBROTHERIID^E (pt. ii. p. 149). 



Poebrotherium wilsoni (pt. ii. p. 149). 



M. 2561 a. Portions of the maxilla and mandible ; from the Miocene 

 of the White River, Colorado, U.S.A. 



Presented by B. Lydekker, Esq., 1885. 



M. 2561 b. An astragalus ; from the same formation. Same history. 



Family TRAGULID^E (pt. ii. p. 150). 



Genus LEPTOMERYX, Leidy '. 



The cheek-dentition is almost or quite. indistinguishable from that 

 of Prodrefnotherium (pk. ii. p. 150), on which grounds Cope 2 has pro- 

 posed to unite the two genera. Leptomeryx is, however, distin- 

 guised by having four distinct metacarpals, although the two meta- 

 tarsals are fused into a " cannon-bone," and the navicular and cuboid 

 are united 3 . 



Schlosser 4 , who places this genus in the Tragulidce, refers 8 Pro- 

 dremotherium and Bachitherium (pt. ii. p. 155) to the Cervidce & ; 

 but the resemblance between the dentition of Leptomeryx and Pro- 

 dremotherium appears too close to admit of their being classed in 

 distinct families ; and the reference of the former to the present 

 family therefore supports the view of Riitimeyer 7 , who includes the 



1 Proe. Ac. Nat. Sci. Philad. vol. vi. p. 394 (1853, vol. dated 1854). 



2 Tertiary Vertebrata of the West (Rep. U. S. Geol. Surv. Terr. vol. iii.), 

 Book i. p. 37 (1884). 3 Schlosser, inf. cit. 



4 Morphol. Jahrb. vol. xii. p. 75 (1886). 5 Ibid. p. 65. 



8 The Cervidce, together with the other Pecora, are regarded by this writer 

 as subfamilies of the Gelocida.

 der Hirschfamilie ' (Abh. Schw. pal. Ges.), pt. 2, p. 68 : this view id adopted in 

 part ii. of the present work.
