Creodus incertae sedis II. 
Plato xxxvii, Ggs. 10-22. 
A number of pieces of the skeleton of a species supposed to be a Creo- 
dont were found in connection with a superior molar tooth of appropriate 
size, as well as with fragments of some smaller Mammals. It is uncertain 
whether the tooth belongs to the species represented by the bones; should 
it so belong, it refers the animal away from the three genera in which the 
superior molars are known, and leaves the question of its pertinence to 
Didymictis uncertain, as in that genus the superior molars are unknown.' 
In the crown of the tooth in question, two external cusps are regularly 
trihedral and acute; within these is an extensive tubercle with crescentic 
base, whose horns terminate at the internal bases of the outer cusps; it has 
two apices, a small one at the base of an outer cusp, the other at one side
