The reproduction and cytology of the Notostraca (Crustacea, Phyllopoda).


  • *W.A. Fisheries Research Institute, Freetown, Sierra Leone.


Both bisexual and hermaphrodite reproduction occurs in the Notostraca. The form of the gonads is described and the cytological cycle of ovaries and testes reported briefly.

The most successful chromosome counts were made on the early spermatid nuclei, seen abundantly in smears of nearly mature tests. These counts were confirmed by chromosomes found in the testis lobes and ovaries of other animals.

An account of copulation is given and methods of fertilization are discussed.
