8. The fragment of a last molar tooth. Tr. Am. Phil. Soc. X., pl. 37, fig. 18. Re- 
ferred to Protochoerus prismaticus. 
9. Three inferior canines and a much worn lower molar tooth. 
10. Small fragments of an upper and a lower jaw, of an atlas and of several ribs; three 
mutilated lower extremities of the humerus; fragment of a radius; two thirds of a hip bone 
and fragments of a second ; an entire femur seven inches long and two and one third inches 
in circumference at the middle of the shaft; fragments of another femur, fragments of 
two tibie; three calcanea; two astragali; fragments of two metacarpals ; two first pha- 
langes, and one second phalanx. All these specimens appear to have been derived from 
three individuals, and the same to which the fragments belonged which were supposed to 
characterize Platygonus compressus and Hyops s. Dicotyles depressifrons. 
The specimens of the list from number 2 to 10 inclusive, were obtained by Mr. Snyder 
of Galena, from the vicinity of that city, and have been presented by Dr. Le Conte, to the 
Academy of Natural Sciences, where they are now preserved. 
11. The incisive portion of the lower jaw, with the right canine tooth. Referred to D%- 
cotyles costatus. Obtained through Dr. R. W. Gibbes, from Benton Co., Missouri, where it 
was found in association with bones of the Mastodon, and presented to the Academy of 
Natural Sciences by Dr. Le Conte. 
12. Two much worn upper and two lower canines; fragments of a lower jaw, with an 
entire series of molars of one side, and four molars of the opposite side; three last lower 
molars of as many other different individuals; fragments of the lower jaw of a young in- 
dividual containing the last temporary and the first permanent true molar; three upper 
and two lower incisors. Also, besides a quart measure full of small fragments of vertebrae, 
and of bones of the extremities, the following:—fifteen mutilated vertebrae; part of a 
scapula; two humeri embedded in ferruginous sand, and measuring seven inches in 
length; lower extremity of another humerus, one inch and a half in transverse diameter ; 
two olecranon processes; several carpal bones; a pair of co-ossified metacarpals, three 
inches long and one inch wide at the base; several isolated metacarpals, and halves of me- 
tatarsals; four first phalanges, two second, and two last ones; portions of two hip bones; 
extremities of four femora; one patella; two heads of tibize, measuring one inch and three 
quarters in transverse diameter ; distal end of another tibia; two calcanea, two and three 
quarter inches long; one astragalus, and several other tarsal bones. All these specimens 
were obtained by Dr. Edward Kittoe, from the lead crevices of the cliff limestone rocks of 
Galena, Illinois, and have been presented to the Academy of Natural Sciences. 
13. A fragment of the lower jaw, of a young animal, containing the last temporary molar 
unworn. The first permanent true molar had not yet commenced to protrude. The 
specimen was from Augusta Co., Virginia.
