MAMMALIA. 
Issel are described, which comprise L. isselensis , L. tapirotherium y and L. 
occitanus. The third chapter gives an elaborate comparison of all the 
known forms from other localities with those from Issel, 3 species being 
new. In the fourth chapter we have descriptions of the species of Pachy- 
nolophns found at Issel, of which P. parvulus is new. In chapter five 
there is a brief notice of a Creodont Carnivore ; while the eud of the 
memoir has a resume of the conclusions derived from the Mammals. The 
plates illustrate the dentition and osteology of Lophiodoi >, Pachynolo- 
phus , &c.
