Mr. Donovan, like ourielves, gave Ellis credit for this 

 fliell, and has figured it as an EngliJ}} produ6tionj confeffing 

 however that he has neither found it himfelf, nor ever re- 

 ceived it from any of his friends ; but informs us tlie fpeci- 

 men in his poITellion is fuppofed to be the fame that was 

 fent by Mr. Ellis to the Dutchess of Portland, and was 

 afterwards in the cabinet of Doctor Fordyce, at whofe 

 death he obtained it under the title of Lepas segellatum of 

 Solander, 



We are happy to have it now in our power to identify 

 this rare fpecies of Lepas as truly Britijlo, having been fa- 

 voured with a recent fpecimen from our late conchological 

 friend Mr. Bryer, who took it on the fl^ore near Wey- 

 mouth, fmce the publication of Teflacea Bn'tan?tica. 



This fliell is of a blueifli horn-colour, very thin and dia- 

 phanous : the lower anterior valve is concentrically wrinkled 

 from the exterior angle at the bafe, and faintly radiated 

 with Jlrice from the fame point acrofs the wrinkles : the 

 bafe of this and the correfponding valve are curioufly dilated, 

 or reflexed : the upper valve is alfo a little wrinkled ; the 

 apex flightly hooked backwards : the dorfal valve, which is 



fub-carinated.
