Sowerby's figure is both, badly drawn and coloured, and the de- 

 scription is also incorrect. The sulci are coarser than there repre- 

 sented, tbe epidermis is blacker, and the posterior side is not 

 "broadly truncated," but curved.

This species, published in 1861, figured and redescribed in the 

 following year, and since twice quoted in catalogues of the genus 

 by Prime, is stated by Sowerby to be " — ? MS. Hanley's collec- 

 tion," a statement characteristic of this careless monograph.

This species, regarding which there is much confusion, was 

 described by Lesson in. the 'Yoyageofthe 'Coquille," the volume 

 (vol. ii.) which contains the description bearing the date 1830 on 

 the titlepage. The description, however, was evidently written 

 before this, as Lesson's preface bears the date January 1828. 



I think there can be no doubt that Deshayes likewise described 

 the same shell in the ' Encyclopedie Metbodique,' which also is 

 dated 1830, notwithstanding that he himself subsequently, in the 

 British-Museum Catalogue, holds his species distinct. In his
