Pleistocene. Port Kennedy, Montgomery Co., Penna. Canine molar. 



This species and M. loxodon are probably based on aberrant forms of M. 

 •wheatleyi. The improbability of four species of Megalonyx, distinct from M. 

 jeffersoni, occurring side by side in the same bone pit, is further emphasized 

 by the fact that many intermediate forms between specimens taken as the 

 types of Prof. Cope's species- are to be found in this collection. I concur 

 with Prof. Cope that M. wheatleyi seems entitled to rank as distinct from 

 M. jeffersoni.
