, and described ''Bostryx turritus tamboensis'' (shell height/shell width = 2.87) from the same locality, albeit from different elevations (1500 m resp. 1000 m). According to Haas (1955) – reporting a locality at 1360 m – his shells ‘are slightly more slender than the typical form’. The specimens from Catzcal show a variation in ration shell height/shell width from 2.84 to 3.18 (mean 3.00; n = 7). It is possible that this variation can also be found in the populations at the localities in La Libertad, in which case ''Bostryx turritus tamboensis'' should be considered a synonym of the nominate taxon.
