A systematic work, containing descriptions and references to all the 
well-established genera of existing as well as many extinct Mammals. A 
table of the classification of the orders and families is given on pp. 88-92. 
The illustrations include figures of the external form, and of the 
dentition, osteology, and viscera of a large number of types. A few 
emendations have been made on the authors’ previous views as to the 
employment of certain generic terms, while some are used in a wider 
sense than formerly. Thus, Neomeris is included in Phoccena, and all the 
Oxen are ranged under Bos. A few new generic names have been pro- 
posed to replace preoccupied ones. [See Phocidce , Pteropodidce , Emballo- 
nuridcn } and Phyllostomatidai.]

Discusses recent theories as to the primitive plan of structure of Mam- 
malian molars and the homologies of their various cusps. Also the 
theories as to the influence of pressure aud position on the form and 
wearing of teeth.

The opinion that Aulaxiuuus is identical with Macacus ( Inuus ) is dis- 
puted, and it is regarded as a form connecting the Seninopithecince and 
Cercopithecince i Dolichopithecus and Mesopithecus being placed with the 
former. In a discussion on the European Pliocene Hyaenas, it is con- 
sidered that too many species have been named. The paper concludes 
with an assertion of the right of the name Maclicerodus to supersede 
Meganthereon.
