Extract

The species of Hymenolepis Weinl. described in the following pages was collected from the small intestine of a greater black-backed gull, Larus marinus, shot on the Dovey mudflats near Aberystwyth, in February 1935. Comparisons of the dimensions of scolex and strobila, measurements of rostellar hooks and suckers, and appearance of genitalia, prove beyond doubt that the species is identical with that described by Linton (1927) under the name of Hymenolepis fusus (Krabbe) (vide Table infra). From the data tabulated in the discussion below, the writer is satisfied moreover that the species described by Linton is totally distinct from Taenia fusus Krabbe 1869, and the new name Hymenolepis neoarctica is therefore proposed to include Linton's species. Since the description by Linton dealt only with the morphology of the immature forms, the following account of the morphology of the mature worm is given, based on material collected at Aberystwyth.
