he has discovered the group of the Simocyonide inter- 
mediate between bears and wolves ; the genus Hyzenictis 
which connects the hyzenas with the civets ; the Ancylo- 
therium, which is allied both to the extinct mastodon 
and to the living pangolin or scaly ant-eater; and 
the Helladotherium, which connects the now isolated 
giraffe with the deer and antelopes. ’ 
Between reptiles and fishes an intermediate type has 
been found in the Archegosaurus of the Coal forma- 
tion; while the Labyrinthodon of the Trias combined 
characters of the Batrachia with those of crocodiles, 
lizards, and ganoid fishes. Even birds, the most appa- 
rently isolated of all living forms, and the most rarely 
preserved in a fossil state, have been shown to possess 
undoubted affinities with reptiles; and in the Oolitic 
Archeeopteryx, with its lengthened tail, feathered on 
each side, we have one of the connecting links from 
the side of birds; while Professor Huxley has recently 
shown that the entire order of Dinosaurians have re- 
markable affinities to birds, and that one of them, the 
Compsognathus, makes a nearer approach to bird orga- 
nisation than does Archzopteryx to that of reptiles. 
Analogous facts to these occur in other classes of 
animals, as an example of which we have the authority 
of a distinguished paleontclogist, M. Barande, quoted 
by Mr. Darwin, for the statement, that although the 
Paleozoic Invertebrata can certainly be classed under 
existing groups, yet at this ancient period the groups 
were uot so distinctly-separated from each other as 
they are now ; while Mr. Scudder tells us, that some of
