As compared with the described species, the characters of the Mesoteras 
kerrianus are well marked. Thus the earbone is totally different from 
that ot Eschrichtius cephalus and E. mysticetoides ( Balaena Emmons, 
Leidy) and the mandibular ramus is not flattened above as in E. priscus 
and E. expansus. The paucity or absence of external foramina distin- 
guished it from the E. polyporus. Finally, E. leptocentrus presents 
generic characters in its known cervical vertebrae which will not probably 
be found in the present whale. Though these vertebrae of Mesoteras 
have not been found, I anticipate that they will present more nearly the 
characters of the genus Ealaena, in accordance with the remainder of the 
structure. They are probably entirely different from those of Paloeo- 
cetus of Seeley. 
It has been known to geologists and others for some time, that a 
skeleton of some kind had been exposed by the erosive action ot the 
waters of a creek in Eastern North Carolina, and was to be seen lying in 
its bed diagonally across it. The writer recently visited the spot, and 
found the stream to be some fifty feet in width, containing water of from 
three to five feet in depth. The direction and extent of the skeleton was
