PARAMYS MAJOR Loomis 



U.S.N.M. No. 18442, right mandibular fragment witli M1-2 and roots 

 of M3 (loc. No. 48FR76) ; U.S.N.M. No. 18441, left mandibular frag-

 No. 48FR80). 



This specimen does not agree with the figures (Matthew^, 1918, 

 p. 617) of the type in that the enamel is entirely smooth and not 

 rugose. Consequently, it is only provisionally referred to this species 

 pending the acquisition of better material.

 Genus PROLIMNOCYON Matthew 



PROLIMNOCYON ANTIQUUS Matthew 



U.S.N.M. No. 18444, left mandible with P3-4 and roots of M2.3 (loc. 

 No. 48FR76) ; U.S.N.INI. No. 19445, both mandibles with only roots 

 of teeth preserved (loc. No. 48FR,65) .
