CORRIGENDA. 



For Ostrea prona, p. 29, read Oslrea ventilabrum, Goldf. 



Ostrea pulchra, p. 30 ; this name should be restricted to the small shell from Bromley ; the large shell 

 from Reading, figured in Plate L is probably a distinct species, which might be called Ostrea pulcherrima. 

 For Modiola Deshayesiana, p. 76, read Modiola Deshayesii.
