Amphidromus sulphuratus, common name the canary-bird bulimus, is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Camaenidae. ^[1]

Description

Shells can reach a length of about 50 millimetres (2.0 in). ^[2]

(Described as Bulimus sulphuratus) The sinistral shell is cylindrically oblong and slightly fusiform. It contains six to seven convex whorls. These are smooth or very finely longitudinally striated. The columella is broad and somewhat callous. The aperture is rather small, the outer lip is reflected. The shell is deep citron yellow, with a white lip and columella. ^[3]

(Described as Amphidromus maculiferus cosmius) The very thin shell is elongate-ovate. It is yellowish-white, with moderately rounded whorls appressed at the apex. The initial two whorls exhibit a faint, narrow dark band immediately above the suture. Subsequent whorls are marked by irregularly disposed, hyaline axial bands of variable width, most pronounced on the third and fourth whorls. The body whorl displays weak axial threads, the remaining surface showing only incremental growth lines. The aperture is ova. The outer lip is slightly expanded and reflected, thin and white at the margi. The inner lip is short, somewhat twisted, broadened at the base, and partially reflected over the narrow umbilicus. The parietal wall is covered by a thin, pale rust-colored callus. ^[4]

Distribution

This species can be found in the Philippines, Indonesia, Vietnam and Cambodia.
