from "Walton-on-Naze, Jersey, Swanage, and Burnham-on-Croucli ; 

 fossil from the Fluvio-marine Crag of Thorpe and the Red Crag of 

 several localities in Suffolk. 



Mr. Cooper also exhibited a specimen of Petricola plioladiforinh, Lam., 

 of which he gave the following account : — 



" In April, 1895, I found at Buruham-on-Crouch, Essex, a shell, which 

 Mr. E. A. Smith identified as Petricola pholadiformis, Lam. It was picked 

 out of a large heap of oyster and whelk shells, which had been dredged in 

 the river. One valve was considerably broken, but this was probably 

 owing to rough usage ; the fresh condition of the specimen points to its 

 having lived in the river, where it was probably introduced with oysters. 

 Mr. W. Crouch has also found an example of this species at Buruham." 



On behalf of Mr. Brockton Tomlin sinistral specimens of Helix 

 nemoralis, L., were exhibited from Bundoran, N.W. Donegal. 



Mr. E. R. Sykes exhibited a catalogue, partly priced, of the sale 

 of the Duchess of Portland's collection in 1786. 



A vote of thanks was passed to Dr. and Mrs. "Woodward for their 

 kind hospitality.
