4 In Plate lxvii. of the ' Fauna Ant. 

 Siv.' two varieties of Merycopotamus 

 are figured : ' M. major ' and ' M. minor,' 

 and in one manuscript note written 

 in 1846, by Dr. Falconer, the genus 

 is divided into two species, viz. M. 

 dissimi/is and M. nanus. This sus- 

 picion as to two species seems to have 



been confirmed by a specimen from 

 Attock sent to the author in 1857 by 

 Dr. Oldham. This was the last upper 

 molar, and was compared with the cor- 

 responding tooth of Merycopotamus dis- 

 similis in the British Museum (No. 

 1075 a) with the following result: — 



iter. Mer. of 



dis. Attock 

 Length of last molar . 1 - 1 075 

 Width of ditto in front 1-2 0'8 



The author adds : ' The difference in 

 area is so great that the Merycopotamus 

 of Attock must have been a distinct 

 species.' — [Ed.]
