NOTES ON THE CANID.E OF THE WHITE RIVER OLIGOCENE. 



few specimens of these phalanges which I have seen are without the bony hood around 

 the base of the claw, haying much the appearance of the unguals in the viverrine genus 

 Oynogale. It is possible that the apparent absence of the hood may be clue to the break- 

 ing away of that delicate structure, but this does not seem very likely.

The species of Daphmnus hitherto recognized are three in number, two of them, I), 

 vetus Leidy and D. hartshornianus Cope, from the White River stage, and the third, D. 

 cuspigerus ('ope, from the John Day. Two additional species are described in the sequel, 

 one of which, however, can be referred only provisionally to the genus, until more com- 

 plete material has been obtained, though the species in question is evidently very closely 

 allied to Daph&nus, if not actually referable to it.
