 Section to inauf.urate the conchological scries by the issue of a 

 list showing the distribution of all the s]iecies and varieties of

 who also include in the paper critical remarks on the synonymy 

 and differentiation of the species in continuation of the work 

 begun by Dr. Jeffreys in his classical work. For the recording of

 physical configuration. Of this list the first sheet is before us, 

 including the species of Spheriu/n (4 and 3 varieties), Pisidium 

 (5 and 4 varieties), Unio (3 and 3 varieties) and Anodonta (2 and
