On the Round Worm Genera Protostrongylus and Angiostrongylus of Kamensky, 1905

Extract

In “An account of some helminthes contained in Dr. C. M. Wenyon's collection from the Sudan,” published in the Third Report of the Wellcome Research Laboratories at Khartoum, I drew attention in 1908 to the importance of the mouth armature of the Bursate Nematodes and suggested the regrouping of the various genera into three separate families: Strongylidæ, Metastrongylidæ and Eustrongylidæ. The Strongylidæ were divided into three and the Metastrongylidæ into two sub-families. Under the sub-families were listed the names of those genera which I then thought fell into each group, but to none did I append the name of the author or the date of the genus. The genus Protostrongylus occurred in the list of genera of Metastrongylinæ. Where, as in Trichostrongylinæ and Metastrongylinæ new names were suggested, these were indicated by the insertion of N.N. after each. Yet in two important compilations dealing with the classification of the Nematodes published during the present year the authors place on me the responsibility for proposing the generic name “Protostrongylus.” Thus in Baylis and Daubney, page 253, the name is listed Protostrongylus Leiper, 1908, and it is stated that “this name is mentioned by Leiper among genera attributed to his sub-family Metastrongylinæ. No species is mentioned and the name appears to be a nomen nudum.” Yorke and Maplestone similarly listed the genus Protostrongylus Leiper, 1908, among those genera insufficiently known and of uncertain systematic position, stating that it is one “belonging to the sub-family Metastrongy linæ.
