A notice of this important paper on Eocene Mammals was inserted 
last year from Ann. Sci. Nat., but certain of the new species were missed, 
and they are therefore now included. [See Viverra leptorhyncha and 
Ilerpestes crassus ( Vivcrridce ), and Plesictis mutatus ( Musteliclce ), spp. nn.]

A valuable work, illustrated with excellent figures, on some of the more 
interesting of the numerous fossils discovered in the Upper Eocene 
deposits of Quercy. Like the last, it was quoted in the 1882 Record from 
other notices, but these having been too incomplete for proper reference, 
its contents are now noted in their proper places.

This is, for systematic zoology, by far the most important publication 
of the year, as it contains an excellent original account (1) of the general 
anatomy, osteology, development and distribution of Mammals, and (2) 
of the members and classification of the various orders. The fossil 
are treated in connection with the recent forms, and there is a section 
devoted to the Mesozoic Mammals, which do not fall naturally into any 
of the recent orders. In the systematic part, the anatomy and palaeont-
