In the foregoing table the writer follows Prof. Mivart 1 in referring all existing 
cats to the genera Fells and Cyncelurus. In opposition to that authority Pseudcelurus 
is, however, placed among the lowest forms, instead of next to Fells : a position to 
which it seems entitled by the large number of premolars sometimes present, 2 as 
well as by the well-developed talon of m. 1 : 3 according to Prof. Cope, the first lobe 
of the blade of pm. 4 is absent, but this apparently is not the case in the specimen 
figured by Gervais. The form of the two mandibles does not seem to bear out 
Prof. Mivart’s suggestion 4 that JElurogale is the same as 
Dinictis. The genus Machcerodus is taken as including 
the American forms, classed by Prof. Cope in the distinct 
genus Smilodon ; characterized by the smaller size, or 
suppression of pm. 3 ; and, at all events in some forms, 
by the union of the zygomatic with the mastoid process 
beneath the auditory meatus. In M. neogeeus (fig. 15) 
and M. fatalis pm. 4 is more complex than in any other 
form ; its first lobe being nearly as large as the 
second, with a large talon in front of it : pm. 4 also 
is unusually complex. In placing Eusmilus higher in

America. Mivart : Prof. Cope, however, places it at the top 
of his Nimravidce. Its high specialization is indicated by the suppression of
