Captious Leptachatina Snail (Leptachatina captiosa)
This species was described in 1911; it inhabited the Wai’anae Mountains on the island of O’ahu, Hawaiian Islands.
The shells reach sizes of about 1 cm; they are minutely perforate, ovate, corneous, nearly solid, scarcely glossy, faintly and closely striated with growth lines; the aperture is rather large, subovate, very slightly oblique and nearly perpendicular; the columella is nearly straight, arcuate below and bears an acute callus along its face; the outer lip is slightly arcuate and distinctly thickened; the umbilicus is very minute.
