Eggshell formation in polyclads (Turbellaria)

Hydrobiologia, 1986
Eggshell formation in polyclads was studied by means of transmission electron microscopy and histochemistry. Shell-forming granules (SFG) in the egg, as well as secretions of shell glands (SGS), play roles in eggshell formation. As the oocytes pass through the portion of the female tract where the shell glands open, they are surronded by a two-layered ...

Revision of Koinocystididae (Turbellaria)

Zoologica Scripta, 1980
The revision deals with the anatomy and systematics of the known 38 species of Koinocystididae. The taxonomy within the family is revised, a key for the identification of live specimens is given and an attempt is made to reconstruct the phylogeny of genera and species on the basis of anatomical transformation series. New genera are Axiutelga. Brunetia,
