GASTEROPODA. 



I. — Marine. 



Chiton (Acanthochites) fascicularis L. Britain. 



C. (A.) fascicularis var. gracilis Jeffr. Milford Haven. 



Labelled "C. discrepans Brown?" I can answer for 

 it that it is not so. In the first place there is only one 

 English locality (out of the Channel Islands), and that 

 is in Cornwall; and secondly the granules are distinctly 

 round, whereas in C. discrepans they are always oval. 

 Besides, Jeffreys gives Milford Haven as a locality in 

 which MacAndrew had taken this var. gracilis.
