The purpose of the present application is to secure the continuation of the currently stable use of the generic name Eubranchus Forbes, 1838, by the suppression under the plenary powers of several nomina dubia and the designation of a new type-species for the genus. 2. In 1838 Forbes (Malac. Mon.: 5) introduced the new generic name Eubranchus for the new species Eubranchus tricolor Forbes, 1838, which is therefore the type-species by monotypy. 3. In 1855 Alder & Hancock {Mon. Brit. Nud. Moll.

One group had the type indicated as tricolor Forbes, 1838, and the other as Eolis cingulata Alder & Hancock, 1847 {Mon. Brit. Nud. Moll.: fam. 3, pi. 28). The authors, however, gave no indication of whether they considered one or other of these species as the type of Galvina. The first designation of a type-species for Galvina was by Iredale & O'Donoghue (1923, Proc. malac. Soc. Lond. 15 : 208) who chose Eubranchus tricolor Forbes, thus making Galvina a junior objective synonym of Eubranchus. Three years later {Proc. malac. Soc. Lond. 17 : 127) O'Donoghue tried to establish Eolis farrani Alder & Hancock, 1844 {Ann. Mag. not. Hist. 13 : 164) as the type of Galvina, erroneously citing farrani instead of cingulata (6) to place the family-group name eubranchidae Odhner, 1934 (Brit. Antarct. {Terra Nova) Exp. Nat. Hist. Kept., Zool. 7 : 278) (typegenus Eubranchus Forbes, 1838) on the Official List of Family-Group Names in Zoology. Lemche, H. 1964.
