to the genus Archoeolemur . In view of the extraordinary diversity v^^hich we have 

 seen in the skulls of this genus, it is not surprising that there should be considerable 

 variations in the size of these bones. Without attempting to determine with any 

 certainty the various species to which these humeri should severally be referred, it 

 seems probable that the long, somewhat slender one numbered 13 may be the 

 humerus of Archceolemur edwardsi, the somewhat shorter and stouter ones (11 and 

 12) those of A. platyrrhinus ; while the one indicated in the table as 14, which though

much more slender than the preceding is of the same general type, may possibly be 

 the humerus of Archceolemur majori, though no skull of the latter species occurs in 

 the collection *. 



It Avill not be needful to describe in detail this series of bones. Their mo&t 

 interesting feature is the fact that they show many points of agreement with the 

 humerus of the members of the genus Lemur. The proximal end of the humerus of 



* None of the arm-bones of ArcJiceolemur in our collection appears to equal in size those figured by 

 Dr. Grandidier in his recent memoir as belonging to Bradylemvr rolnisti's, so that this form will stand 

 as a fourth species of Archceolemur.
