& cuts. 
Discusses the structure of the members of this and the next two 
families, all of which are placed in the suborder Litopterna , of the order 
* Taxeopoda .’ The Macraucheniidce and Proter other iidce are characterized 
by having upper molars of a Palseotherioid type, with V. s., while those of 
the Astrapotheriidce (Homalodontotheriidce) are rhinocerotic, with straight 
outer walls. The structure of the carpus and tarsus is described as 
Taxeopodous ; and the various genera of the three families are defined. 
A curious parallelism between the members of this group and the Equidce 
and Rhinocerotidee is noticed.
