B. tulipa of Müller is the [B. Hameri] of this work, under which name full information on its geological history has been given. The B. tulipa of Poli and Ranzani is the [B. tulipiformis] of the present work; and this latter species is said by Philippi to occur fossil in Sicily. But there has been so much confusion in the identification of [B. tulipiformis], [B. Hameri], and [B. tintinnabulum], and likewise of [B. perforatus] (which by Poli was wrongly considered to be L. balanus, Linn.), that doubts must be entertained about which have been really found, until the Sicilian fossils are all carefully examined.
B. ovularis, Lamarck: see remarks under B. pustularis.
B. Uddevallensis, Linnæus, is probably a synonym of the [B. Hameri] of this work and the B. tulipa of Müller.
[A few other references may be added to those given by Bronn.]
B. miser, stated by Lamarck to be found fossil: see remarks under B. pustularis.
B. patellaris of Lamarck, is stated by Marcel de Serres to be found fossil with several other species of [Balanus]; thus named without any description in the ‘Annales des Scien. Phys. et Nat. de Lyon,’ tom. i, p. 417.
B. virgatus, delphinus, and crispus, are names given by Defrance, with absolutely worthless descriptions.
B. radiatus is too briefly described by Risso (‘Hist. Nat. de l’Europe Merid.,’ tom. iv, 1826), without a figure, to be recognised; it probably is not the B. radiatus of Spengler, Wood, and other authors.
B. goissopomo, lævis, and radiatus, are mere names without any description, published in a Catalogue by F. Hoeninghaus, in the ‘Jahrbuch für Mineral. Geog.,’ &c., 1831, p. 155.
