downwards; the color is yellowish-brown, the columella very 

 much arcuated. In the general form, sculpture, and color of 

 the shell G. fischeri somewhat resembles large specimens of 

 Limnaea palustris. It is intermediate in form between G. 

 filosa and G. pseudoturris ; but is distinct from both by the 

 much more blunt apex (like that of G. audebardi), the some- 

 what coarser sculpture near the suture, and the' arcuated colu- 

 mella" (Martens).
