Studies on the helminth fauna of Alaska. 43. Strigea macropharynx sp. n., a trematode parasite of Falco rusticolus L.

Strigea macropharynx sp. n. (Trematoda : Strigeata, Strigeidae), an intestinal parasite of Falco rusticolus L., is described. Falconiformes harbor two species of Strigea (S. falconis Szidat, 1928, and S. macroconophora Dubois and Rausch, 1950) with vitellaria terminating near the copulatory bursa. Both differ from the new species in having a pharynx that is smaller than or subequal to the bucca...

Studies on the Helminth Fauna of Alaska. Xlii. Aploparaksis Turdi Sp. N., a Hymenolepidid Cestode from Thrushes.

Aploparaksis turdi sp. n. (Cestoda: Hymenolepididae) is described from the robin, Turdus migratorius L., and recorded also from the varied thrush, Ixoreus naevius (Gmelin), from Iliamna Lake, upper Alaska Peninsula. This cestode is distinguished from the three previously known species of Aploparaksis s. 1. occurring in passeriform birds by the size and number of rostellar hooks and by the arran...

Studies on the helminth fauna of Alaska. XLIV. Revision of Ogmogaster Jägerskiöld, 1891, with a description of O. pentalineatus sp. n. (Trematoda:Notocotylidae).

Discrepant conclusions in the literature concerning the specific distinction of the two species assigned to the genus Ogmogaster Jagerskiold, 1891, necessitated a reevaluation of the taxonomic characters used in separating these trematodes. Study of material from baleen whales from North Pacific waters and from baleen whales and lobodont pinnipeds from the southern hemisphere disclosed the exis...
