Hedgehogs, but have no ])Ower of rolliiig themselves up. The 

 " Bauxrings " {Tiqxiia) of the Indian Aixbipelago have a long, com- 

 pressed tail, and live mostly in trees. 



Before passing on to the next oider, a few woi'ds must be said 

 about a curious transitional form, which has been alternately pilaced 

 in the Cheiroptera, the Insectirora, or the (ituadrmnana, or has been 

 regarded as the type of a separate order. The animals alluded to 

 are the so-called Flying Lemurs {Galeopithecus), of which more than

one species is known as iidiabiting the Indian Archiiielago. The 

 leading characteristic in these singular animals is the possession of 

 a flying membrane, which extends as a Ijroail expansion fi-om the 

 nape of the neck to the arms, from the arms to tlie hind-legs, and 

 from the hind-legs to tlie tail. The fingers are not elongated, and 

 do not su]3port a " patagium," so that the animal has no power of 

 true flight, but can sinijily take extended leaps fi'om tree to tree. 

 The Galeopitkeci live chiefly upon small insects and birds, and the}' 

 should probably be i-egartled as aberv.ant fnrms of the Insrrticora.
