CONCHOLOGICAL NOTES FROM PICARDY. 



Having recently visited Abbeville and Amiens I append 

 lists of the Land and Freshwater shells which I observed during 

 a search of not more than half an hour near each place. 



There is no more delightful district for a quiet holiday 

 than the valley of the Somme, and I hope that the publication 

 of these imperfect records will show how well a careful investi- 

 gation would be repaid, and induce other conchologists to 

 complete them.
