    there are two kinds of reproductive bodies in Lacinularia: 1. Bodies which resemble true ova in their origin and subsequent development, and which possess only a single membrane; 2. Bodies half as large again as the foregoing, which resemble the ephippium of Daphnia, like it, have altogether three investments, and which do not resemble true ova, either in their origin or subsequent development, which, therefore, probably do not require fecundation, and are thence to be considered as a mode of asexual reproduction.
