 A small specimen, answering well to Darwin's account of 

 this species, sent me by Mr. H. W. Bell-Marley, was taken in 

 37 m. depth, off Bird Island. 



OPERCULATA. 



FAMILY BALANID^E. 



GEN. BALANUS, Ellis? or Da Costa. 



1778. Balanus, Da Costa, Hist. Nat. Test. Brit, (see Darwin, 

 Balanidse, p. 177), and British Conch., p. 249 (see 

 Sherborn, Index Animaliurn, p. Ivii). 



1789. B., J. G. Bruguiere, Ency. Meth. (Vers) (i) 1789, xii & 158. 



Tom. i., pt. 1, pp. 1-344, though dated on title-page 1792, 



was published in 1789, as shown by original wrappers. See 



Sherborn and B. B. Woodward, Ann. Nat. Hist. Ser. 7, 



vol. xvii., p. 579. 



1854. B., Darwin, The BulanicUe, Ray Soc., p. 177. 



1902. B., Sherborn, Index Animalium, pp. Ivii, 104, 1083. 



Sherborn does not include Ellis as an authority for Balanus, 

 no doubt on the ground (mentioned by Darwin) that in 1759 

 he was not a binomial authority. The reference to Da Costa, 

 accidentally omitted from Sherborn's general list, is supplied 

 on p. Ivii, supplementing Darwin's reference by giving p. 249 

 for the occurrence of Balanus in Da Costa's Conchology. 

 Darwin, Balanidse, p. 204, accepts Ellis as authority for 

 B. tullpiformis, referring to Phil. Trans., vol. 1. (1758), pi. 30, 

 fig. 10. But the date should be 1759, the plate number 34, 

 and, for the reason given above, the species should be accre- 

 dited to Darwin himself, not to Ellis.
