This species is often taken for a variety of Vertigo Sirangei, Pf., 

 the time typical species of Yet tigo Strangei are sinistral, more elon- 

 gated, and the aperture oval, studded with seven teeth. Dr. Cox 

 in his "Monograph of Australian Land Shells, 1868," figures my 

 species as a variety of V. Strangei, in plate 14, fig. 18, 18 A ; both 

 species are found in company.
