SABELLIDAE. 471 



vidensk. selsk. Forhand., 1856, p. 13) ; but that author brings no species definitely 

 into connection with his brief diagnosis of a single clause, saying merely that 

 for "de Sabeller, hos hvilke begge Gjaellebuskene danne Spu-aler, ma udji're 

 en sjaette Slaegt, hAdlken man maske kunde kalde Bispii-a." In 1870, Claparede 

 (Ann^lides Chetop. Golfe Naples. Suppl., 1870, p. 429) mentions the genus in com- 

 ments on Bispira volutacornis Rathke as a representative. Any shght evidence 

 available in Kroyer's paper would indicate that this species is the one which he 

 had in mind. At any rate, it is fixed by Claparede's use as the type. TMs species 

 was renamed rubripundata by Grube who showed that Rathke's species is not 

 identical with the Amphitrite volutacornis Montagu, type of Quatrefages's DistyUa. 

 Furthermore, St. Joseph (Op. cit., p. 285) points out that Rathke's species 

 {rubripundata Grube) belongs in Jasmineira Langerhans (1880), though that 

 author retains Bispira Kroyer in the sense of Distyha. It seems impossible to 

 justify this procedure. Here Bispira is accepted as estabhshed by Claparede's 

 use of it in 1870 and as replacing Jasmineira. Distylia Quatrefages is used in 

 the sense given to Bispu'a by St. Joseph. 



St. Joseph (Op. cit., p. 250) merges Mana^-unkia Leidy with Haplobranchus 

 Bourne (1883), giving the latter precedence; but Leidy's first account was pub- 

 lished in 1858 (Proc. Acad. nat. sci. Philad., 1858, p. 90; 1859, p. 2), his paper 

 of 1883 (Ibid., 1883, p. 204, pi. 9) being merely an extension of the earlier one, so 

 that in such case Manayunkia must be used. Dybowscella Nusbaum is also 

 exceedingly close to these forms. 



Aspeira Bush is included in Potamilla Malmgren. Metachone Bush is 

 left apart tentatively, but is hkely to be found inseparable from Chone Malm- 

 gren. 



The following are synonyms of Myxicola Koch : Eriographis Koch, Ai-ripasa 

 Johnston (the type of which, Amphitrite infundibulum Montagu, is also the type 

 of Myxicola) and Leptochone Claparede. This genus has sometimes been 

 included in a special family, the Eriographidae (Eriographides Malmgren). 



Amphicora Ehrenberg and Othonia Johnston are synonyms of Fabricia 

 BlainviUe. 



Grube suggests that Rathke's species stigmatosa, for wMch he proposed the 

 genus Clymeneis, is a Sabella that has lost its branchiae. 



Potamis Ehlers, preoccupied in Lepidoptera (Hubner, 1816), is replaced 

 by Potamethus, nom. nov. 



Oria Quatrefages (1865), being preoccupied (Hubner, Lep. 1816, Desv., 

 Diptera 1863), is here replaced by Oriades, uom. nov.
