General Description

Description. General appearance. Living specimens are 10–14 mm long. The anterior body end is somewhat enlarged, slightly flattened and rounded. The cerebral organs open into a pair of short transverse slits. The mouth is slightly stretched longitudinally. The posterior body end is rounded and enlarged. The integument is whitish, semitransparent; a yellowish or pale pink intestine is seen. At low magnification, one can observe a small white structure (probably corresponding to a cluster of subepidermal glands). In fixed specimens, the body is usually spirally coiled, the head being narrower than the trunk.
