This species has only hitherto been recorded from the Cape 

 Peninsula, whence Mr. Sclater mentions a specimen in the 

 S. African Museum from Table Mountain, and Mr. Grant obtained 

 one at Tokai, near Simonstown, at an altitude of 600'. The 

 exact locality of the type has not been recorded. 



A. subspinosus maybe distinguished from other members of the 

 genus by the structure of its molai's, which are more brachyodont 

 than in A. selousi, and difier in certain of the cusp details. They 

 are also markedly narrower.

 that spring up wherever spaces have been cleared in the forest." —
