Amphidromus roeseleri is a species of air-breathing tree snail, an arboreal gastropod mollusk in the family Camaenidae. Description. The length of the shell attains 47 mm, its diameter 27 mm. (Original description in Latin) The sinistral shell is semi-obtectly perforate (partially covering the opening), presenting an ovate-conical shape and a solid structure. Its surface appears transversely slightly striatulate (with fine grooves) and is decussated (criss-crossed) by very fine and close-set but very distinct spiral lines, giving it a silky, white appearance. The spire is moderately elongate with somewhat convex sides and a blunt apex. The shell contains six moderately convex whorls. The body whorl reaches almost the middle height of the shell. The aperture lies moderately oblique and has a somewhat ear-shaped form. The peristome appears rather broadly expanded, white-lipped, and somewhat reflected. The columella is straight and striated, forming a somewhat distinct angle with the basal margin, and is very callous (thickened), dilated (widened), and revolute (turned back) above, almost covering the perforation. Distribution. This species is endemic to the Sulu Archipelago,the Philippines.
