CORRIGENDA. 
For Ostrea prona, p. 29, read Ostrea ventilabrum, Golde. 
Ostrea pulchra, p.30; this name should be restricted to the small shell from Bromley ; the large shell 
from Reading, figured in Plate I, is probably a distinct species, which might be called Ostrea pulcherrima. 
For Modiola Deshayesiana, p. 76, read Modiola Deshayesii.
