. Whorls are rounded, first whorls very narrow, the last one very large, and embracing the preceding one, distinctly descending in front. The umbilicus is deep, and very small (about 1/20 of the width of the shell) and partly hidden by the expanded columellar side of the peristome. The aperture is crescent, a little oblique. The peristome is very thick and expanded all around and somewhat reflexed. The two ends are connected by an extremely thick callus, forming a very strong and quite sharp arcuate tooth on the body of the penultimate whorl. The width of the shell is 18.2-24.6 mm. The height of the shell is 10.7-14.0 mm. The width of the holotype is 21.7 mm. The height of the holotype is 13.0 mm. So far, this most remarkable species can not be confused with any other ''Chloritis'' species because of its peculiar appearance; so far it is the only species with such a strong and sharp arcuate tooth.
