SABELLIDAE. -171 



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

 into connection with his brief diagnosis of a single clause, saying mc^n^ly that 

 for "de Sabeller, hos hvilke begge Gjaellebuskene danne Spiraler, ma udj0re 

 en sjaette Slaegt, hvilken man maske kunde kalde Bispira." In 1870, Claparede 

 (Annelides Chetop. Golfe Naples. SuppL, 1870, p. 429) mentions the genus in com- 

 ments on Bispira volutacornis Rathke as a representative. Any slight 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. This species 

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

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

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

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

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

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

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

 the sense given to Bispira by St. Joseph. 



St. Joseph {Op. cit., p. 250) merges Manayunkia 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 likely to be found inseparable from Chone Malm- 

 gren. 



The following are synonyms of Myxicola Koch: Eriographis Koch, Arripasa 

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

 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 

 Blainville. 



Grube suggests that Rathke's species sligmatosa, for which he proposed the 

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



Potamis Ehlers, preoccupied in Lepidoptera (Hiibner, 1810), is replaced 

 by Potamethus, nom. nov. 



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

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