the latter being about one and one-third times the vertical diameter 

 of the orbit in the females, and two or more times this diameter in 

 the males. 



PLATYGONUS INTERMEDIUS, new species. 



Type. — The greater portion of a male skull lacking the condyles 

 and the basicranial region (Cat. No. 8148, U.S.N.M. Coll.) . Paratype, 

 a nearly complete skull of a female. Cat. No. 8147, U.S.N.M, Coll. 



Type locality. — Cumberland Cave. 



Diagnosis. — General characteristics much as in P. cumherlanden- 

 siSj but differing from that species as follows : Skull smaller ; denti- 

 tion and especially the canines relatively larger (see table of com- 

 parative measurements p. 668) ; diastema behind canines relatively 

 shorter. A species with teeth relatively large for size of skull.
