Obs. I do not know where to place this singular worm. My spe- 
cimen was sent to the British Museum. 
Desc. Body an inch long, cylindrical, tapered at the posterior end, of a 
dirty light brown colour, annulose, rough with numerous papille and hairy. 
No head nor eyes. Tentacula projected from the anterior extremity, com- 
pletely retractile, of two kinds ; for two of them are filiform, equal, yellowish 
and fleshy ; and eight of them—placed above and within the first—-are seta- 
ceous, bristle-like, and of a bright grass-green colour. There are likewise 
about the anterior end numerous long bristles in indistinct fascicles, which, 
when magnified, appear distinctly jointed similar to a Conferva. Along 
each side a row of about sixty feet, one pair to each ring. The feet are pa- 
pillary, each bearing about four unequal bristles, not retractile : those of the 
two or three anterior pairs are longer than the others. Anus terminal, 
simple. The animal can inject a green-coloured liquid into a central vessel 
of the fleshy tentacula. 
One specimen found amongst the entangled roots of Laminaria digitata.
