Jickeli (1874) remarks: “I could not unite Plan. salinarum, 
Morel., from West Africa, with riippellii ; according to the figure in 
Voy. Wellwitsch, the former differs through less height combined 
with greater diameter. On the other hand, our Abyssinian Planorbis 
appears to me very nearly allied to Plan. pfeiffert, Krs. ; comparison 
with examples of this species, which I do not possess, ought to 
produce synonymy of the two.”
