HE genus Hyrax is distinguished from all the 

 rest of the Glires by the remarkable circumstance 

 of having four teeth in the lower jaw instead of 

 two : these lower teeth are also of a different 

 structure from the upper, being broad, short, and 

 crenated or denticulated at the top : the upper 

 teeth in this genus are also less sharp or pointed 

 than in the rest of the Glires. In other particu- 

 lars the genus Hyrax seems most nearly allied to 

 that of Cavia.
