224 DOUGLASS — CRETACEOUS AXD LOWER TERTIARY. [Aprils, 



of P. cavirictis, and there is nothing to distinguish it from that 

 species. 



Paniolambda (?) sp. (Plate XXIX, Figs. 11-13.) 



An upper premolar, much smaller than P^ of P. bathmodon or P. 

 cavirictts, but it is possible that it may be a P ^ of nearly as large a 

 form. It is very doubtful, however, whether it belongs to Panto- 

 lambda at all. The protocone is more conical, the outer slope on 

 the median line of the tooth is steeper and the inner less so. The 

 outer surface near the base of the crown is more concave. 



A canine found with the above is not like that of the known 

 species of Pantolambda, but can hardly be distinguished from that 

 of modern Carnivores. It probably belongs to some Creodont.
