 to that of a cetacean mammal is noteworthy.

The total length of the anterior limb could not have been less than 0"V.M), 



which allows of live phalanges in the longest digit. There may have been 

 more. That the digits were of unequal length is indicated by portions of 

 two in matrix accompanying the specimens, where the articulation of two 



phalanges falls opposite the shaft of one of the adjoining digits. The pha- 

 langes were separated by a short interval of cartilage.
