6o COOKE : NOMENCLATURE OF BRITISH NUDIBRANCHIATA. 



I have ventured to append a revised classification of the whole 

 group, based upon Bergh.- Dr. Norman, in his "■Revision of British 

 MoUusca," •"' which unfortunately still remains incomplete, has drawn 

 up a classification of our Nudibranchiata, on somewhat, but by no 

 means entirely similar lines to this. 



P. 33. Alderia modesta, Loven. — The reference to an article 

 by Allman is beside the point. Read Stilitje)' modcstus, 

 Loven, Oefv. K. Vetensk. Akad. Forh., i (1844), p. 49. 

 Alderia sp. Allman, Rep. Brit. Ass., 1844, p. 65. Not 

 Stiliger modestus, Ehrenberg. 

 P. 35. Fiona nobilis, A. and H. — Substitute Fiona marina, 

 Forsk. — Liviax marinus, Forskiil, Descr. Anim. (1775), 

 p. 99; Icon. Rev. Nat. (1776), pi. 26, f. G. 

 P. 36. Embletonia minuta, Forbes and Goodsir. — The reference 

 to Rep. Brit. Assoc, 1839, is altogether inadequate. That 

 Report (Trans, of Sections, p. 80) contains no description 

 whatever, only short mention of species. The species in 

 question was described by Forbes and Goodsir in '^Atlienanim," 

 1839, P- ^47) "O'^ however as '^ Eolidia rninnta," but as 

 " ]'Joli(Ja minima." The paper is entitled ''Notes on zoological 

 researches in Orkney and Shetland during tJie month of June, 

 1839, hy Ed. Forbes and John Goodsir.'" The mistake, 

 started by Forbes and Hanley and continued by Alder and 

 Hancock in their monograph, has been current ever since. 

 P. 37. EoLis PAPILLOSA, Linne. — This is one of the few British 

 MoUusca which were described by Linne in the 12th, but not 

 in the 10th, edition of the " Systema." He described it also 

 in the 2nd edition of the " Fanna Sueciea," the date of which 

 is intermediate between the two above-mentioned editions of 

 the "Systema." The reference therefore should read : Fauna 

 Suec. (1761), p. 508, no. 2093. 

 P. 39. EoLis coronata, Forbes. — For " Forbes " read " Forbes 

 and Goodsir." The article in the "AtJiemeum" is that in 

 which Emhletojiia minima (referred to above) was described, 

 and it is a curious accident which has attached the name 

 of both authors to one of the species therein described, and 

 the name of one of them only to another. 

 P. 40. EoLis elegans, a. and H. — For "p. 315 " read "p. 316." 

 P. 41. EoLis LiNEATA, Lovcn. — For '' E. lineata, Lov., Ind. 



2 Semper, Reisen im Archipel. der Philippinen, vols, i, 2 and Suppl. 



3 Ann. Mag. Nat. Hist., 1890, 6 ser. vi, pp. 70—91.
