Family： Camaenidae 南亞蝸牛科

Scientific name： Amphidromus metabletus pachycheilus f. fusca

Chinese name：

Author： von Möllendorff, 1901

Size： 34.6mm

Description： Juvenile, Nha Trang, Vietnam.

Subsp. Pachychilus is stronger-shelled throughout, thicker lipped, parietal callus stronger ; suture more distinctly margined; base less wide than Amphidromus metabletus.

The individual variations are even more numerous than in the type, the following " forms " being distinguishable :

A (flava), uniform yellow. (for nomenclatural purposes equivalent to pachycheilus).

B (alba), uniform white.

C (tritaeniata), yellow with 3 brown bands, the middle one sometimes lost.

D (trizona), white with 3 bands.

E (interrupta), like D, but the bands interrupted and reduced to rows of spots.

F (confluens), like D, but the bands more or less widened and confluent.

G (fusca), uniform brown by widening and union of the bands, except for a white sutural line.
