Type material.

Originally, the type series consisted of four specimens (the holotype and three paratypes) housed in the Geological Department of the Stanford University under accession number 5776 ( Baker 1934). Later, two of the paratypes were given to ZMB and are kept now under No. 90524. Their label contains an indication that the shells origin "from type lot". The larger of two shells is 12.8 mm height that a little less than size reported by Baker (1934).

Type locality.

USA, Utah, near Logan, Cash Co.

Current taxonomic allocation.

Hubendick (1951) believe Stagnicola impedita to be a synonym of Lymnaea palustris (O.F. Müller, 1774), but it is incredible since this Palearctic species does not live in North America ( Burch 1989; Johnson et al. 2013).
