Cuba, Moll, i, p. 161, pi. viii, f. 20-23 [errore 



16-19 — H. mauriniana]. 

 [Pfeiffer {Mon. Helic, i, p. 87) cites " Helix mauriniana. 

 Orb cub. 1, p. 162, t. 8, f. 20-23 " as a synonym of 

 his H. saxicola {Arch. Naturg., Jahrg. vi, bd. i, May, 

 1840, p. 251). Since in subsequent volumes Pfeiffer 

 continues to treat H. minuscula as a separate species, 

 It IS obvious that in the above citation he has merely 

 copied the erroneous reference to the figures eiven
