Megalonyx. Some of the teeth, however, seem to belong to a different 
genus. Some years ago, Capt. Dudley Avery found a claw core, which 
he sent to the Smithsonian Institution, and which was there pronounced 
to be that of a Megalonyx. This was found near this spot, and in a 
deposit of the same age. | 
Part of the antler of a deer was found in the southeast corner of the 
excavation ; but I am not certain whether it came from the blue clay, 
or from the much more recent deposit containing human vestiges, which 
here dips down almost to the level of the salt. In the blue clay, how- 
ever, near this spot, we found vertebre resembling those of a very 
large deer, with four molar teeth of some herbivorous animal, probably 
a ruminant, whose precise affinities are yet undetermined. 
Among the miscellaneous specimens are water-worn fragments of 
coniferous wood, from the blue clay. These are in perfect preserva- 
tion. There is also a soft stercoraceous mass, found about the junction 
of the blue clay and loam, apparently the dung of some large herbivo- 
rus animal.
