Matadi, December 27, 1914. The adult and juvenile are preserved as 

 skins with skeletons, the embryos are preserved in formalin. 



A novelty of the collection was Chapin's bush hyrax, secured as near 

 to the mouth of the Congo as any hyrax is apt to occur. The reduced 

 number of mammae (if the type specimen is indicative) set this species 

 apart from others of the genus, and its nearest neighbor, Heterohyrax 

 bocagei, is quite different in its longer, thicker pelage, smaller size, 

 broader teeth, proportionately broader skull, elevated supraorbital 

 ridges, shorter muzzle and flatter basicranium. (See Plate XXII.)
