Head end rounded, submedian lobes very small. The posterior margin of the annules is very finely crenate. Vulva apparently slightly open; the vagina runs almost transversely in its distal part.

However, I prefer to keep it apart because of the shape of the posterior body end (in morgensis tapering, truncate) and the appearance of the vulva: in morgensis it is distinctly closed in lateral view, situated on the middle of the annule; in hemisphaericaudatus it appears slightly open in lateral view (ventral view shows it to be closed really) and lies between two annules. In morgensis the vagina runs obliquely to the vulva, in hemisphaericaudatus almost transversely. Finally the crenation of the posterior margins of the annules appears more coarse in morgensis than in hemisphaericaudatus. Whether C. annulatus Taylor, 1936 is identical with morgensis or with hemisphaericaudatus cannot be decided for the moment: vagina direction suggests the former, tail shape the latter (Cf.
