17140. The cranium of a male, with the greater part of the left 

 horn-core. This specimen shows very clearly the charac- 

 teristic intercornual concavity of the frontals. 



39564. The greater portion of the cranium of a female, showing the 



(Fig.} base of the horn-cores. This specimen is described and 



figured by Riitimeyer, op. tit. p. 151, pi. iii. figs. 3-5 ; a 



very similar example is figured by the present writer, op. 



tit. pi. xxi. fig. 1, and pi. xxi. B. 



48016. Calvarium, with the bases of the horn-cores, of a young 

 (Fig.} individual. Riitimeyer (op. tit. p. 150, pi. iii. fig. 6) 

 describes and figures this specimen. 



48018. Part of the cranium of a young individual. Noticed by 

 Riitimeyer, op. tit. p. 150. 



39562. The anterior portion of the cranium, in a much-crushed 

 condition. Noticed by Riitimeyer, op. tit. p. 151. 



Bubalus antilopinus (Falconer and Cautley 1 ). 



Syn. Amphibos antilopinus, Falconer and Cautley 2 . 

 Probubalus antilopinus, Riitimeyer 3 . 

 Hemibos antilopinus, Lydekker 4 . 



This species is probably a less specialized form of the B. octipitalis 

 stock ; it is readily recognized by its subcylindrical horn-cores (re- 

 calling those of the female of that species), which are closely approxi- 

 mated at their roots, and by the extreme breadth of the lower portion 

 of the skuU. 



Hob. India.

 the type specimen, and is described and figured by Riiti- 

 meyer, op. tit. p. 135, pi. i. figs. 5, 6.
