B. stellaris, Bronn (‘Lethæa Geognostica,’ tab. 36, fig. 13). To this species, Lepas stellaris (I presume a misprint for stellata) of Poli, is given as a synonym; but the Lepas stellata of Poli is a [Chthamalus], and this certainly is not the case with B. stellaris. I have received two specimens from the Continent named B. stellaris, but they certainly differed from the form so called by Bronn, for in that, the parietes are said to be porose and the radii very narrow: these foreign specimens I have named [B. inclusus]. A species described by me as [B. corrugatus], resembles in external appearance the B. stellaris of Bronn, but it is mere labour in vain to attempt identifying Balani by their external characters.
B. striatus, Defrance: see remarks under B. circinnatus.
B. tertiarius, Risso, ‘Hist. Nat. de l’Europe Merid.,’ vol. iv. I cannot recognise this species.
B. tesselatus, Sowerby, a synonym of [B. porcatus]; recent and fossil: see remarks under B. costatus.
B. zonarius, Münster: see remarks under B. ornatus; possibly this is a synonym of [B. concavus].
B. amphimorphus, Lamarck: see remarks under B. pustularis.
B. crispatus, var. of [B. tintinnabulum].
B. cylindraceus, Lamarck. From Chenu’s ‘Illust. Conch.,’ in which work Lamarck’s original specimens are figured; it appears that this is the [B. psittacus] of South America, where it is also found fossil, but assuredly Lamarck is quite in error when he states that a variety of this species occurs fossil near Turin. Bronn (in his ‘Italiens Tertiär-Gebilde,’ p. 127) gives as a synonym to the Turin fossil the Lepas tintinnabulum of Brocchi (in the ‘Conchologia Fossile Subapennina,’ t. 2, p. 597), and this probably is correct; and I have hardly any doubt that the Lepas tintinnabulum of Brocchi is the B. concavus of Bronn described in the present work.
B. perforatus of Bruguière is said by Philippi to be found in Sicily: see remarks under B. tulipa.
B. semiplicatus, Lamarck: see remarks under B. pustularis.
