I’m thinkin’ about the pictured shell, found dead in the south of Thailand, Prov. Krabi, at the shore of a large pond in Krabi Town, 18.12.2005. Hight of shell: 59,94 mm, width 56,83 mm. Brown-olive bandings very weak. Spire low, sutures scarcely impressed (see figs. 3 and 4). Might be Pila ampullacea or Pila angelica?
Thanks for your trouble......: wolf
