^ See note on p. 28. 



' Dr. T. S. Palmer has kindly called my attention to the fact that the generic name Eupro- 

 togonia is antedated by Tetraclanodon^ a genus of Creodonts founded by Prof. Scott on 

 Mioclirnus Jioveriantis of Cope, a wrongly interpreted specimen of Etiprptogonia puercensis. 

 The generic description of Tetractcenodon is doubtfully valid, very misleading, and founded on 

 error ; the name is inappropriate in the extreme ; and I have therefore retained Euprotogonia 

 as a well known and appropriate name substituted for the original preoccupied name 

 Protogon ia .
