thecus cannot be regarded as being either a lemur, iusectivore or 

 bat, but that it stands alone, the sole representative of an ancient 

 order, Galeopithecidse, as Hyrax does of Hyracoidea, While 

 Galeopiihecus is but remotely related to the Lemuroidea and Insec- 

 tivora, it is so closely related to Chiroptera, more particularlyMn 

 regard to the structure of its patagium, brain, alimentary canal, 

 geuito-uriuary apparatus, placenta, etc., that there can be but little 

 doubt that the Chiroptera are Ihe descendants of Galeoplthecws, or 

 more probably that both are the descendants of a GaleopUhecus- 

 like ancestor.
