On Some Gregarines from the Prawn, Parapeneopsis Sculptilis (Heller)

Abstract

Many species of cephaline Gregarines have been previously described from hosts belonging to widely different orders of Crustacea. These parasites are referred to the families Cephaloidophoridae Kamm, Gregarinidae Labbé, Porosporidae Léger, and Didymophyidae Léger. Kamm (1922) gave a list of these parasites, instituted the new family Cephaloidophoridae, and gave a description of all the species, except those referrable to Porosporidae, as till that time it was generally believed that Porosporidae were Schizogregarines. She fully discussed the grounds for placing the genus Cephaloidophora Mawrodiadi in a family by itself, and transferred to this genus several species previously described under Gregarina or Frenzelina.
