for the named varieties : and that it should aim at procuring 

 examples of every known variety of our home species, so as 

 eventually to accumulate a series which any conchologist might 

 find worthy of a special journey to consult. 



Mr. John W. Taylor read a letter from Mr. Robert 

 ScHARFF of Bordeaux announcing the discovery of a Pupa new 

 to France, the Pupa daustralis of Gredler, and a variety new to 

 science, just described by Dr. Bottger, Pupa Strobeli var. Scharffi. 



SUCCINEA OBLONGA Drap. 



Mr. John W. Tavlor exhibited on behalf of Mr. Robert M. 

 Christy of Brighton a specimen of this shell, found, apparently 

 fossil, in the alluvium near the city of York, being the only 

 specimen known to have occurred in that district. 



This led to a lively discussion, in which the Chairman and 

 Mr. Thomas W. Bell joined. The question at issue was whether 

 the shell shown was a dead recent one or a fossil. The decision 

 was eventually in favor of its fossil origin.
