). Docoglossate, central teeth and marginal teeth completely lacking, formula 0.1.0.1.0, lateral teeth asymmetrically arranged within a transverse row, the distal third of each tooth is impregnated with ferrous oxides causing the dark brown colour that can be seen by using a microscope. Lateral tooth with long basal plate and a trifid distal part which shows a short and slender inner ramus, a broad, middle, non-determined ramus and a welldeveloped, outer ramus, the middle ramus towers somewhat above the inner and outer rami. In juveniles (specimen of 3.0 mm shell length), the basal plate appears to be weaker and the inner and outer rami appear to be stronger.

The loops of the gut system continue into the visceral mass whereas the large intestine is recognizable by black mineral crystals and greyish flaky material, the stomach is covered by the digestive gland which is situated apically, the rectum crosses the visceral mass diagonally, running parallel to one loop of the intestine. The right kidney and its opening (the urogenital papilla) can be recognized in the excretory system, but the left kidney, which is usually situated anterior to the rectum in

Of the circulatory system, the region of ventricle and auricle can be seen on left side at the base of the gill; a circumpallial vein as well as efferent and afferent branchial veins are clearly visible; capillary vessels could not be detected. Apparently, osphradia are not present.
