OF THE PFEBECK PORMATIOIT. ' 321 



there are several references to the occurrence of Cypridae in the 

 Purbeck beds near Poundsford, Mountfield, and elsewhere in Sussex 

 (pp. 31, 41, 408, &e.) ; but the specific determinations are doubtful. 

 The specimens were noted on the spot by Mr. Etheridge, but have 

 been since mislaid.

Dr. Pitton's wording at p. 177 of his memoir would necessitate 

 the adoption of the name " valdensis " for this form, to the figure of 

 which (his fig. 1, pi. 21) he there refers, were it not that he alludes 

 to Sowerby's description of the real valdensis as Cypris faha (a 

 name by which it was at first known), and especially refers to Sow- 

 erby's figure in the ' Min. Conch.' tab. 485, as weU as to the "profuse 

 abundance " of the species in the Wealden Beds.

* Named after my friend the late Mr. R. A. C. Godwin- Austen, of Shalf ord, in 

 whose company I found the specimen at Peasemarsh, and who directed me to 

 the shale-heap of Upper-Weald Clay, thrown out in digging a reservoir at the 

 brewery there.
