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

 able to learu 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. 



'^ Generally credited to Krinioke, who published the naked name in Bull. Nat. Mosc, 

 1837. 



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



••Both these species of Manduyt are hataviis? according to Moquin Tandon.
