 commenced in the Upper Miocene of (Eningen, and is widely dis- 

 tributed over all the world from the Pliocene upwards. The Wolf 

 (C. lupus) ranges down to the European Pleistocene, and the allied 

 C. Cautleyi is found in the Pliocene of the Siwalik Hills. C. curvi-

 Otocyon (Fennec). Lycaon, now confined to Africa, and distin- 

 guished by having an anterior cusp to the last lower premolar, is 

 found in the Pleistocene of Glamorganshire. Palceocyon, of the 

 Brazilian Pleistocene, is regarded by Dr Schlosser as indistinguish- 

 able from Cams. Temnocyon, of the North American Miocene, has 

 the talon of the lower carnassial secant, and a foramen to the hume-

 represented in the Brazilian Pleistocene, the lower carnassial has 

 not only a secant talon but also lacks the inner cusp. Perhaps, 

 however, the most interesting genus of the whole group is Cynodictis 

 (in which we may include Cynodon, Amflhicynodon, and Pachycyno-
