region was originally heavily forested, but has been cleared and a second 

 growth of brush has taken the place of the original forest which does not 

 grow again. 



It may be added that though some of the Drymceus were collected 

 in August, 1911, and were not received by the present writer until 

 March, 19 12, a certain number of them were still living at the latter 

 date. All the specimens of Phenacotaxus and Peronceus had become 

 entirely desiccated.
