Helix aspersa var. globulosa Baudon, Journ, de Conch., 1884, p. 238. 
SHELL more globose. 
The var. globosa Pic., s.s., is described as ‘‘generally larger and more globose,’ 
and as partial to hedges and orchards, 
The sub-var. globulosa Bandon is depressed and broad, the term ‘ depressa ” 
being said by its author to express its shape. 
The sub-var. megalostoma Bourg. has a short, low spire, an excessively dilated 
last whorl, and a very ample aperture. The var. macrostomea Bourg. of H. Rolle’s 
price list for 1903 is probably a misprint for megalostoma. 
The sub-var. depressa Pauluecci has a solid shell, with thickened lip, and 
resembles H. aperfa in form. 
The sub-var. altieola is described as 464 mill. in diam. and 43 mill. in height.
