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 Hyanthus (naming it in 
honour of D. W. Mitchell, Esq. the Secretary of the 
Zoological Society) ; but it appears to approach nearer to 
Peachia than that species. Fuller observations are much 
needed on botli.
