Note 383 — Chapter XX · PENTASTOMIDA[383]

The animals included in this group are usually called Linguatulidae or Pentastomidae after the two genera or sub-genera Linguatula and Pentastoma. But the animal which Rudolphi in 1819 (Synopsis Entozoorum) named Pentastoma had been described, figured, and named Porocephalus by Humboldt (Recueil d’observations de zoologie et anatomie comparee, i. p. 298, pl. xxvi.) in 1811. The familiar name Pentastoma may, however, be preserved by incorporating it in the designation of the group.
