'Rossmassler credits this and several other species to Zeigler. So far as I am 

 able to learn these are mere manuscript names. Neither Moquin Tandon or Locard 

 give Zeigler as an author in their bibliographies of writers on French mollusks, and 

 Lea refers only to his manuscript. I have not seen his Systematisches Verzeichniss. 



2 Generally credited to Krinicke, who published the naked name in Bull. Nat. Mosc., 

 1837. 



3 Fig. 280, said to be this, is probably U. lnmiduK. 



4 Both these species of Manduyt are lialanis.' according to Moquin Tandon.
