A STERIAS AURANTIACA. Forbes, p. 130. It is so 
rarf * that [ had never seen a specimen, until at the Meeting 
°* the British Association for science, Mr. J. C. Bellamy 
Produced one taketr in Whitsand-bay. It is common in 
j lymouth-sound ; and I obtained a lew specimens from the 
Break water. 
fJ HlURA BRACH1ATA, must be omitted, until dis- 
covered anew.

“ALASSIMA NKPTUNI. Forbes, p. 259. A species 
® common occnrrence from deep water, inhabiting pre- 
dations of stone, which it enters apparently for the 
Purpose of devouring the animal of the shell-fish within. 
Species remaining for examination are chiefly of the genus 
“Ocumaria ; together with one closely allied to the genus 
Psolus of Mr. Forhes. A notice of it was sent to that 
^^ntleman, but too late for publication in his history of this 
aniilv. It was judged by him to he worthy of generic 
ls finction, which is thus marked : under surface extending 
“rough thelenglh, and covered with thickly set suckers, 
in distinct rows. Upper surface covered with tuber- 
a t ’ s > each with an orifice, from which at will is protruded 
cartilaginous point. Tentacnla at the end 13, with club- 
' 'aped foliations on slender stalks. 
Th 
of " e specimen was about six inches long, and of the size 
c e atl ordinary mould candle. Upper surface dark blue; 
r,, le of each tubercle light, enclosing a dark point, and 
the whole a light purple ring 
After death these 
crcles sunk and d isappeared ; so that without pressure 
Op " V could scarcely be perceived. At that end ot the animal 
***. the tentacnla is an orifice, with a small blunt por- 
p ro '"g process; which seems in constant, though slow, action, 
cr e Uc ' n g a slight eddy in the water. When alive this 
of . Ure had a line along its dorsal surface, narrow but frae 
*i(j e _ er °Ies ; and something similar but shorter, on each 
3ft ’ both disappearing when the animal contracted, ar.d 
to f 1 e ath. If it be allowed that this creature is entitled 
ftajp rni the type of a new genus, I would propose for it the 
t5 r m ^ Forbsia, in honour of the Natural Historian of the 
tti Rc * 1 ' nt>| l en nata. 
H it ., place I would insert an account of an animal, of 
euii n a figure was submitted to the inspection of the most
