At p. 198 Darwin says : " I have seen [young] specimens 

 attached to kelp from the Cape of Good Hope, with their 

 parietes white and ribbed, and their radii mottled with pinkish- 

 purple." On p. 200 he says that this species, as one element 

 of its distribution, "ranges from the Island of Madeira to the 

 Cape of Good Hope." 



BALANUS CAPENSIS, Darwin. 



1854. Balanus capcmis, Darwin, The Balanidae, Eay Soc., p. 209, 



pi. 2, figs. 4 a-b. 



"Cape of Good Hope. Attached to stems of Fuci, Algoa 

 Bay. . . . Attached to floating kelp, Lagulhas Bank." In 

 1759 Ellis (Phil. Trans., vol. 1., for 1758) figured this species 

 on pi. 34, fig. 14, as Balanus capcnsis ore obliquo, not a bi- 

 nomial designation, so that the species, if distinct from B. 

 psittacns, Molina, must be assigned to Darwin himself. 



BALANUS CALCEOLUS, Darwin. 



1854. Balanus calceolus, Darwin, The Balanidae, Eay Soc., p. 218, 



pi. 3, figs. 3 a-e. 



A specimen answering to Darwin's account of this species, 

 sent me by Mr. W. H. Bell-Marley, was taken in 37 rn. depth 

 off Bird Island. 



BALANUS SPONGICULA, Brown. 



1827. Balanus sponcjicula, Brown, Illustrations of the Conchology of' 



Great Britain and Ireland, pi. 7, fig. 6. 



The text is confined to the explanation of the plates, 

 unattended by numbering of the pages ; spongicula may be 

 regarded as a printer's error. 

 1854. B. spongicola, Darwin, the Balanidae, Eay Soc., p. 225, pi. 4, 



figs. ~La-d. 



" Lagulhas Bank, Cape of Good Hope, on detached kelp, 

 with B. Capcnsis." 



BALANUS AMPHITRITE, Darwin.
