R. Lydekker — A SIceicJt of tit e 



[No. 1, 



the artiodactyles, we find two species of Sippopotamus, one o£ which 

 (H. namndims) belongs to the hesaprotodont type, while the other (H. 

 palcEindicus) is tetraprotodont, like the larger living species ;* S. 

 palcBindiciis has also been found in the older alluvia of the Jamna. 

 The pigs seem to have been represented by 8m giganteus.\ A species of 

 stag was named by Falconer Cervus nmiadicm, but never described ; 

 a single molar from the Narbada in the Indian Museum is indistin- 

 guishable from the corresponding tooth of the living G. {Buccrvus) 

 duvaucellii. Three species of Narbada oxen have been described, viz., 

 Bos namadicus of Falconer and Cautley, a taurine ox showing some affini- 

 ties to the living Asiatic genus Bibos, also occurring in the Pem-ganga 

 alluvium and, possibly, in the Deccan ; Buhahis of the 



same authors, very closely allied to the living wild Indian buffalo, also 

 found in the Jamna alluvium ; and Leptobos frazeri of Professor Riiti- 

 meyer. A species of nilghai {Portax) has hxtely been described by 

 the same writer from the Narbada rocks, under the name of P. namadicus ; 

 teeth of the same genus have also been obtained from the Pem-ganga allu- 

 ium. 



The Pleistocene rodents are only represented by some incisors proba- 

 bly belonging to the genus Mus, obtained from the Narbada valley, and 

 now in the Indian Museum.

The Recent deposits have not yet, as I have said, in many cases been 

 satisfactorily separated from the Pleistocene, and the very local occurrence 

 of mammalian bones renders this point of doubt one not likely to be soon 

 cleared up. Any alluvial deposits of bones from which Hippopotamus is 

 absent, and which do not contain any other extinct animals, I should be 

 disposed to class as Recent. 



Human remains have been obtained in the alluvium of the plains in 

 various localities, at considerable distances below the surface, but generally 

 in very imperfect condition. Specimens of the teeth and jaws of Macacus 

 rhesus are exhibited in the Indian Museum, obtained from the alluvia 

 of Assam and Madras ; those from the former locality are in a highly 

 mineralised condition. Molars of the Indian elephant have been obtained 

 in the alluvium of the plains of India, and in that of the delta of the 

 Irawadi. A last upper molar of Hhinoceros iiidicus has been obtained 

 by Mr. Foote in the alluvium of Madras : this specimen is very interesting 

 as shewing the former range of that species far to the south of its present 

 habitat, which Jerdon gives as " the Terai from Bhotan to Nepal." Sus
