Les Ecrehous : 



Chemin (1934a), 4.ix.l933, in large pools with sandy bottoms along channels between the 

 rock masses at really low water. 



The varied geological formations of the Channel Islands are neither particularly soft nor 

 easily eroded ; all the islands are essentially flat-topped eminences rising steeply from the submarine 

 rock platform. Coastally, they are largely cliffed, with offshore rock reefs and platforms of varying 

 but often gentle slope, considerable extent, and relative shelter from wave-action, especially along 

 eastern-facing coasts. 



Alderney: 



The most generally exposed island to wave-action and fetch, Alderney has been rarely collected 

 and observed; on both counts, it is therefore no surprise to find few records. The one specifically 

 localised instance (Marquand) is from the more protected eastern shore, north side, where there 

 are lower rocky masses containing pools. 



Guernsey : 



The southern and western coastlines are like those of Alderney, exposed to wave-action and
