Gredler, in Verh. Zool.-Bot. Ver. Wien, VI, 1856, p. 114, 

 refers to an earlier publication of Pupa sir obeli in his Bemer- 

 kungen ueber einige Conchylien der Gattungen Pupa und 

 Pomatias, in the Program Obergymnas. Botzen, III, 1853, 

 page not given. I have not seen the work, and do not know 

 whether a diagnosis was given, but the name is anterior to 

 P. rivierwna Bens. 



Mme. Paulucci (Bull. Soc. Malac. ItaL, XII, p. 40) pre- 

 ferred the name P. callicratis Scacchi, 1833. Benoit (Nuovo 

 Catal. Coneh. terr. e fluv. Sicilia, 1881, p. 100) recognized 

 Scacchi 's species; and Westerlund considered it practically 

 equivalent to P. strobeli. See Vol. XXVI, p. 75. On the 

 whole, it will probably be best to call the species Truncatel- 

 lina callicratis (Scacchi). 



The account of De Stefani's varieties quoted from Wester- 

 lund in Vol. XXVI, p. 75, contains several errors. The fol- 

 lowing is from De Stefani's publication, which we now possess. 



Vertigo callicratis forma nodosaria De Stefani (Bull. Soc.
