groups of the Primates. Although the author limited himself 

 almost exclusively to outer characters, his practised eye very often, 

 aud, so far as rhe genus Lemur is concerned, as a rule, hit upon 

 the truth. His shortcomings are due to the lack of sufficient 

 collections, and the entire neglect of cranial characters, considered 

 by him to be " un terrain glissant." 



In the following paper I have done my best to contribute to a 

 better knowledge of two species of the genus Lemur, with especial 

 reference to some characteristic features of their skull. Inci- 

 dentally have been pointed out the cranial characters of a third 

 species, one which is almost always confused with Lemur mongoz L.

Anticipating the result of the following detailed review, I may 

 state at once briefly the history of the name " Lemur mongoz." 



Linnseus based his species upon the tolerably good figure and 

 the good description of " The Mongooz " in G. Edwards's Gleanings. 

 Schreber ^ and soon afterwards Gmelin ' extended the name to
