longitudinally striate ; aperture simple, with one internal 

 tooth opposite to the mouth, very obscurely designated in 

 some specimens, which are therefore intermediate between 

 this variety and the type.

Puna layardi, Benson, Ann. & Mag. Nat. Hist., December'18o6 ; id. ibid, 

 ser. 3, vol. xiii. (1864) p. 496 ; Mel v. & Pons. Proc. Mai. Soc. Lend. 

 (1898) p. 177 ; PfeifFer, Mon. Helic. Viv. iv. p. 674, vi. p. 318; id. 

 ( Vertigo, Alcea) Nomencl. p. 358. 



We treat this dextral species as a Pupa, relegating the 

 sinistral forms alone to the subgeneric Fauxulus { = Faula, 

 H. & A. Ad., 1858 *, pr^occ.). 



In Mr. W. H. Benson's revised description (/. c. p. 496) a 

 var. minor is alluded to, about which some uncertainty exists. 

 What is P. stoapkora, Benson, and when described? Can 

 tills be a synonym of the var. minor? Neither we nor 

 Dr. R. Sturany f can trace the species. 



Alt. 5^-7, lat. 2-3 mm. {Benson).
