species in having three pairs of incisor teeth in both jaws ; but the one found in 

 Europe seems inseparable from the modern larger African species. Of smaller size 

 are species from the caves and fissures of Sicily, Malta, and other Mediterranean 

 isles. Among these, one from the limestone caves of Cyprus was of even smaller 

 size than the one from the Maltese bone-fissures, and only about half the dimensions 

 of the common African species. This Cyprian species, the H. minutus of 

 Cuvier, apparently displays affinities on the one hand with the living pigmy 

 hippopotamus of West Africa, and 

 on the other with an extinct Italian 

 representative of the group. The

 Tertiary mammals of the Mediterranean islands were slightly modified survivors of 

 species which disappeared at an earlier date from the adjacent mainland.
