The true date of the genus is very uncertain, since in 

 vol. viii. of the Ges. Nat. Freunde the fourth part, which, like 

 the third, is dated 1814, actually contains an article on the 

 weather of 1816 !

 on a " Coronula taken from skin of hump-back whale cut up 

 in Table Bay, 16-6-77." Several fine specimens of this species 

 have also been sent me by Mr. H . W. Bell-Marley. They are 

 seated on Coronula diadema, from a hump-back whale taken 

 at Durban. A striking figure of the two cirripede species 

 combined is given as early as 1759 by Ellis (Phil. Trans., 

 vol. 1., pt. 2, for the year 1758, pi. 34, figs. 1 and 7). Ellis,

 Balanus or Concha anatifera, but that Linnaeus distinguished 

 the fish or actual animal as Triton, and called the covering 

 Lepas. In the explanation of plate 34, under Lepades 

 pedatae, fig. 1 is named Lepas nucla carnosa aurita, rendered 

 into English as " Barnicles with stems," and " naked fleshy
