GEOGRAPHICAL DISTRIBUTION OF THE SPECIES. 



Five species are here recognized as belonging to the genus Chiro- 

 gale, all natives of the Island of Madagascar. It cannot be said that 

 the limits of their dispersion are as yet definitely ascertained, especially 

 of those comparatively lately described, as of these we know little 

 beyond the locality in which they were discovered. The one most fa- 

 miliar to Mammalogists, the C. major Geoffroy of this work, C. milii 

 Auct., seems to have a rather extensive range on the Island, and is 

 found from Pasandava on the north west coast to TuUare in the south, 

 and on the east coast from Fort Dauphin in the south east, and in 

 Betsileo Province in the lower wooded region, to Tamatave in the 

 north east, and also according to Shaw in Central Madagascar. C. 

 melanotis has been obtained at Vohemar on the north east coast, and 

 C. sibreei was taken at Ankeramadinika one day's journey east of 

 Antananarivo the capital, but the extent of the range of neither is 

 known. C. crossleyi was procured by Grandidier in the forest of 

 Antsianak, and C. trichotis was found by Mr. Crossley between 

 Tamatave on the north east coast and Morondava on the west coast, 

 but we have no knowledge of the limits within which the ranges of 

 these two species are restricted. It is not improbable, however, that 

 they may have a considerable dispersion in Central Madagascar.
