genera mentioned, cusp 6 rises some distance behind the anterior 
end of the tooth and is connected by a more or less obvious list 
or ridge with 4; this list may individually become divided into one 
or more cusplets. The same is the case with Canis (diagr. 11), 
but here 4 is quite small and 1 has 
totally disappeared, consequently 6 is 
placed just inside the front border of 
the tooth. — Characteristic for p? is 
thus the rudimentary condition of 1 and 
the often strong development of 4 — just 
the reverse condition of that found in

In Procyonidæ (together with Melini,

1896) pt acquires one element more, a cusp 7 arising behind 6, 
but being supported by the same root. (fig. 12, diagr. 13). The 
successive evolutional stages are clearly shown in the series Bassaris- 
Procyon-Ælurus. It corresponds to Osborn's hypocone and gives 
the tooth a bunodont character. — In the strange genus Æluropus
