In a list of German and Austrian shells (Nachrbl. D. M. 

 Ges., 43, March 1911, p. 24) C. E. Boettger has "Vertigo 

 (Alaca) alpestris Aid.," followed by seven other species; 

 under the same generic and subgeneric names. As Alaea 

 occurs above it on the same page, it is possible that Alaca is 

 intended as a new section, and not a typographical error for 

 Alaea. In that case it may have V. alpestris for type ; but I 

 am inclined to think it unintentional, as it is not designated 

 as new. 



CRATICULA Lowe, P. Z. S., 1854, p. 211 (March 27, 1855), 

 type designated as P. substriata Jeffr., becomes subordinate to 

 Vertigo, and can be used as a sectional name for the group of 

 V. substriata (see Manual, Vol. 25, p. 172) if that is consid- 

 ered sufficiently distinct to need special designation.
