FROM THE EDDYSTONE GROUNDS TO START POINT. 



391 



stray specimens of species which are typical of coarser grounds than 

 the present. This suggests the presence of such grounds near it, and 

 it is not unlikely that they will be found on the unexplored area 

 between the present ground and the Bolt Head Shell-gravel, Ground 

 XVII. (See Chart I.)
