This fragment I found in one of te a ravines on the 
western side of the Shockoe Creek Ravi 
In one of the species of Zeuglodon ins by Miller, ris 
exists a lower jaw with a prolonged symphysis as in thea 
specimen, though the teeth of the first are less numerous. ‘He 
also figures a portion of an upper jaw which is turned up, pre- 
senting a convexity corresponding with the concavity of the 
outline : be lower fragment here described. Fig. 6. : 
n addition to the above, there have been found from. time to 
time for Bir years, fragments of bones of the larger Cetaceans,. 
of which I have numerous specimens, but have seen none of the — 
dimensious of those of the largest existing whales. Their spe-- 
cific characters have not been recognized. I have a single im-— 
_ perfect tooth nearly five inches in length, the crown of which is 
quite small compared with the root, and its surface is irregularly - 
Striated or reticulated as in the figures of the teeth of Zeuglodon, 
given by Johannes Miller in his memoir on this last animal, . *
