THE SCARLET PEARLET. 233 



direction. The tentacle that is opposite the mouth-angle on each side is 

 wholly dull purple, with pale bands almost obsolescent. 

 Mouth. Lip rich scarlet. 



Size. 

 Length about two inches ; greatest diameter one inch. 



Locality. 

 The coast of Dorset ; deep water. 



This very fine species came into my possession in the 

 spring of 1853, when I was engaged in collecting marine 

 animals for the tanks of the Zoological Society of London. 

 It was obtained by one of the Weymouth trawlers, who 

 fish chiefly off the west side of Portland. As it remained 

 with me but a few hours, and was then forwarded to its 

 destination, the above description and the figure were all 

 I could contribute to its history. The species has not been 

 met with since. 



I associated it with Forbes's Uyantlius (naming it in 

 honour of D. W. Mitchell, Esq. the Secretary of the 

 Zoological Society) ; but it appears to approach nearer to 

 Peaclua than that species. Fuller observations are much 

 needed on both.
