title: [The effect of brain removal and ovariectomy on the development of clitellian glands of Piscicola geometra L. (Annelida, Hirudinea, Rhynchobdella)].
abstract: In Piscicola geometra maintenance of clitellar glands secretory activity is not connected with the cerebral neurosecretion. On the other hand their evolution is not under the influence of the ovaries; ovariectomized leeches copulate and lay cocoons.
