Note.— The Nucula-bed {N. deUoidea) at Colwell Bay (mentioned at page 49 and elsewhere) contains Cythere 

 Colwellensis, C. debilis, C. angulatopora, C. cornuta, and C. plicata ; the last-mentioned species presenting the most numerous 

 individuals. 



Note. — I have not been able to recognise among the London Clay specimens the species figured as Cytherina barbata, 

 by Mr. Sowerby, in the ' Geological Transactions,' 2d series, vol. v, pi. 9, fig. 1. The specimen itself has been lost. It is 

 possibly referable to Cytheridea perforata.
