Extract

In January, 1921, I published in Parasitology (Vol. xn. No. 4, p. 337) a brief description of what appeared and still appears to me to be a new species of Porocephalus, and I commented upon the fact that this species exhibited “the most marked form of sexual dimorphism yet discovered in the Linguatulidae” and is therefore of some interest. Two writers have recently questioned the validity of this new species. Alcock1 suggests the possibility of my female specimen of Porocephalus pomeroyi being an individual abnormality, and Sambon2 unhesitatingly decides that its peculiar form is merely due to “constriction” and deformity, and records the species as a synonym of his “Armillifer annulatus” —the Pentastoma (Porocephalus) annulatum of Baird, 1853.
