102 MICROCEBUS 



murinus (Miller) ; and M. minor rufus = M. murinus 

 (Miller). Evidently Miller's description of murinus was 

 unknown to the Author, as was also the Bibliography of the 

 species of Microcebus, as some are reinstated, e. g. smithi, 

 rufus, which have been long since relegated to the synoptical 

 list. The paper is one apt to lead investigators astray, by the 

 recognition of individual examples not entitled to any distinctive 

 rank, while Microcebus coquereli (Grandidier), the type of 

 which is in the Paris Museum, is not mentioned at all. 



GEOGRAPHICAL DISTRIBUTION OF THE SPECIES. 



The members of this genus are all found in the Island of Mada- 

 gascar ; some with quite an extensive dispersion, but the range of others 

 has not yet been entirely ascertained. On the west coast from 

 Cape St. Vincent to Tullear on St. Augustine Bay, M. myoxinus is 

 found, and from Cape St. Vincent to Helville on the same coast M. 

 coquereli occurs. M. murinus ranges from Betsileo Province to 

 Fort Dauphin on the south east coast, and northerly from St. Augustine 

 Bay on the south west coast. Its complete range has not yet been de- 

 termined. The species with the greatest known range is M. furcifer 

 which goes from Fort Dauphin on the east coast to Mt. Ambre, and 

 then on the west coast to Cape St. Vincent, thus being found through- 

 out the northern section of Madagascar.
