For identification and registration, specimens may be sent 

 to me, and I am also willing to give directions for collecting and 

 preparing such. 



To several conchologists, I am under obligation for much 

 valuable information, especially to Mr. Bryant Walker, of 

 Detroit, Michigan. 



As it is customary to give the numbers of species listed, the 

 same is done here. The numbers are only approximately cor- 

 rect, e. g., the species of Pleurocera and Goniobasis may be 

 reduced, those of the Sphaeriidae will be added to.
