 p. 183. V. graellsiana was considered to be a form of V. mou- 

 Unsiana by Dr. Florentino Azpeitia Moros, in Boletin Soc. 

 Iberica Ciencias Naturales, xxi, 1922, pp. 101-103. Dr. Haas 

 (Butllet Inst. Catalana Hist. Nat. (2), iv, 1924, p. 13, pi. 2, 

 f. 7), however, calls it V. pygmcea graellsiana, giving a figure 

 (which is here reproduced) of a specimen from Flix agreeing 

 in all respects with Servain's description.

This northern species has been found at Tegel, near Berlin, 

 where it is extremely rare. It is one of the hygrophilous 

 vertigines, according to Th. Schmierer (Archiv fur Mollusken- 

 kunde, liii, 1921, p. 271). Schmierer's figure is reproduced 

 on plate 29. The specimen measures : length 1.5, diam. 1 mm. 



Mr. B. Sundler (Journ. of Conch., xvii, March, 1924, pp. 

 105, 106) records this species from moist meadows around the 

 Varrunn lakes, near Boras, Sweden. Two forms occur, a 

 four- and a five-toothed. He proposes (p. 106) the following 

 varietal names : 



Form quadridens, tooth formula 1-1-2. 



Form quinquedentata, tooth formula 1-2-2.
