 des Mammiftres. 



In this publication a list is given of the species and examples 

 contained in the Paris Natural History Museum. M. griseus 

 is removed from the genus Lemur and placed in that of Hapale- 

 mur ( !) here originally instituted, the writer either having been 

 ignorant of Lesson's genus Myoxicebus or having disregarded 

 it. A new species is first described M. olivaceus as Hapalemur 

 ( !) olivaceus. 



1870. /. E. Gray, Catalogue of Monkeys, Lemurs and Fruit-eating 

 Bats, in the Collection of the British Museum. 

 Myoxicebus simus first described as Hapalemur ( !) simus. 



GEOGRAPHICAL DISTRIBUTION OF THE SPECIES. 



On the eastern coast of Madagascar from the Bay of Antongil to 

 and including Betsileo Province, M. simus has its range; while in the 

 same Province is found M. griseus which also appears in the north 

 west part of the island to Ifassy. The known locality for M. oliva- 

 ceus, so far as I have been able to discover is Ampazenanbe, where an 

 example was procured by M. Lentz, and which is now in the Paris 

 Museum.
