Abstract
DURING investigations on the invertebrates of Lake Tanganyika we have been able to find all the stages of the sessile generation of the well-known Tanganyikan Trachymedusan Limnocnida tanganyicae Günther. We have also collected them in Lakes Mohasi and Sake (Ruanda), where the sexual reproduction seems to be more important. These hydropolyps are completely invisible when living and must be treated first with some fixative (Bouin's or Zenker's fluids); they are very minute (less than 0.5 mm. for one individual) and transparent.
