therefore, premolars, and probably belong either with Meniscoés- 
sus or Cimolomys, or possibly with some other genus the molars 
of which are not represented in this collection. Upper premolars 
of this type are seen in Chirox Cope; Bolodon Owen and Ctena- 
codon Marsh.

No grounds are assigned for separating these 
remains from genera founded upon the teeth.—The astragalus 
bears the same proportion to the molar teeth of Meniscoéssus 
that we observe in Polymastodon; it is also apparently per- 
forated. The affinities of these forms to the Monotremata have 
been observed by Cope; the coraco-scapular facet, therefore, 
strengthens the supposition that some of these bones at least 
belong to Meniscoéssus. In any case, they cannot be considered 
as good types. 
This — the Multituberculate forms. :
