the hinder border of m. 3 measures 0,141 ; the canine, of 

 which the terminal portion is broken away, is relatively 

 large, its antero-posterior diameter measuring 0,023.

16552. The cranium of a female ; from the Pliocene of the Siwalik 

 {Fig.) Hills. This specimen is figured by Falconer and Cautley, 

 op. cit. fig. 5, under the name of M. dissimilis, var. minor. 

 It is in a somewhat battered condition, but shows the 

 whole of the dentition except the incisors, although the 

 crowns of the earlier premolars are hammered off; the 

 first and second true molars are in a well-worn condition. 

 The whole skull is considerably smaller than the last 

 specimen ; the canine is relatively smaller, its antero-pos- 

 terior diameter at the base being 0,018. The length of 

 the space occupied by the three true molars is 0,066 ; and 

 the interval between the canine and the hinder border of 

 m. 3 0,134. The profile of the hinder portion of the 

 cranium being strongly arcuated, is in striking contrast to 

 the same part in M. dissimilis.

18407. The greater portion of the left ramus of the mandible of a 

 {Fig.) male, containing the canine, pm. 3, pm. 4, m. 2, m. 3, and 

 the alveoli of the remaining cheek-teeth ; from the Pliocene 

 of the Siwalik Hills. The specimen is figured by Falconer 

 and Cautley, op. cit. fig. 8. It agrees precisely in size 

 with the male cranium ; the interval between the canine* 

 and the hinder border of m . 3 is 0,163, and the antero- 

 posterior diameter of the canine 0,0295 ; the molars are 

 well worn. Cautley Collection. Presented, 1842. 



15349. The greater portion of the right ramus of the mandible of a 

 {Fig.) female ; from the Pliocene of the Siwalik Hills. This 

 specimen is figured by Falconer and Cautley, op. cit. fig. 7; 

 it shows the last true molar in a well-worn condition, the 

 bases of the preceding cheek-teeth, and a section of the 

 canine. The interval between the canine and the hinder 

 border of m . 3 seems to have been nearly the same as in 

 the last specimen ; but the antero-posterior diameter of 

 the base of the canine is only 0,020. The third lobe of 

 m. 3 is distinguished from that of M. dissimilis by the 

 distinct concavity of its outer surface.
