Speaking of the basis in this species, Darwin says : " It is 

 often penetrated by small rounded irregular holes ; and I 

 have seen specimens from the Cape of Good Hope with parts 

 like a sieve." The date and page of Poll's work are from 

 Sherborn's Index Animalium. Darwin gives no page, and 

 dates the work 1795, when the second volume was published.

Weltner reports the species as taken in the South Sea, at 

 the Cape, by Bergius and by Johswich. Darwin supposed 

 that Bruguiere and Gmelin both published this species in 

 the same year, and, as he did not know which had actual 

 priority, he gave the preference to the better-known name. 

 But the part of Gmelin's Systema which contains this species 

 did not appear till 1790, as will be seen by Sherborn's Index 

 Animalium. Accordingly Bruguiere's specific name should be 

 adopted, the work containing it having a year's priority, as 

 explained above under Balanus.
