324 ON SOME MALLOPHAGAN GENERIC NAMES, 



Dufour described a parasite, Philopterus hreins, from an albatross, 

 this species being made the type of the genus Docophoroides 

 Denny(MSS.) by Giglioli in 1864, a valid generic diagnosis being 

 given. Nitzsch had named the same insect Lipeuriis taurus, but 

 since his description was not published until 1866 (p.385), it 

 cannot claim precedence. Subsequent writers apparently recognise 

 these facts in their synonymy, but Denny's genus has not received 

 due recognition. In 1866, Rudow founded Traheculus for a 

 closely allied parasite, Tr. schilliagi, from a petrel; and, four years 

 later, ignoring his own pi-ior action, created a new genus, Onco- 

 phorus (iiec Oncophora Dies., a nematode genus) with the same 

 type. In 1882, Taschenberg erected Euri/mfi( opus with Lipeurus 

 faurus N., as type, recognised Rudow's Oncophorus schillingi as 

 congeneric, after having examined the type-specimen of the latter, 

 and placed this species under his own genus. Piaget, in 1880, 

 added several species to Oncophorus Rudow, dividing them into 

 two groups, the Docophoroides and the Nirmoides; but he was 

 obviously not too sure of his ground, since, though he included 

 Rudow's species in his descriptions, he did not include it in his 

 key to the genus. Taschenberg having removed 0. schilli/u/i 

 from the geims Oncophorus into his Etirymetopus, Piaget in 1885 

 (p. 35) claimed the genus as "Oncophorus, m." Kellogg( 1896, p. 68) 

 has indicated some of these facts, but has not offered any com- 

 ment, while Neumann appears to have overlooked them, and to 

 have accepted Piaget's genus as being identical with Rudow's 

 Traheculus, which name he allowed to stand. He gave a new 

 name, Taschenhergius, in place of Eurymetopnis, a name already 

 preoccupied as a genus of Coleoptera by Schonherr in 1840. From 

 the foregoing it is obvious that Docophoroides Denny, stands, with 

 Traheculus Rud., Oncophorus Rud., Eurymetopus Tasch., and 

 Taschenhergius Neum., as synonyms, for the forms from petrels: 

 while a new generic name is required for the species from Ballidce, 

 etc., grouped by Piaget and later writers under Oncophorus (0. 

 schillingi and allied Docophoroid forms being excluded). For 

 this group of species, we propose the name RaUicola, which differs 

 etymologically from Rallicida Schleg., 1871, in ornithology. 0. 

 attenuatns N., has been selected by us as the type-species.
