PACHYDEllMATA.. 
We refer to frof. v. Brandt^s ^ SymLolie Sirenologicje^ (see 
/ p. 3), wliicli contains extensive researches into the osteological 
/ characters of the principal Pacliyderm types. 
/ Dr. Oray has examined the species of SuidcB in the British 
/ Museum (Proc. Zool. Soc. 1868, pp. 17-49). He characterizes 
the species and groups into which they are divided, adding the 
synonymy. He lias paid much attention to the configuration of 
the skull, and mentions tlieir more prominent peculiarities. 
After some general introductory remarks on the difficulties of 
understanding the affinities of the various species and breeds, he 
proceeds to arrange them thus :• — 
I. Premolars permanent. 
Fam. 1. SuiDiE. 
A. Typical Swine {Suind).
