The peduncle has a degree of flexibility, enabling the animal to turn 

 the whole a little to one M ! <>r other. But how much has not yet been 

 ascertained A- \.-t it has not exceeded the fifth part of a circle. 



Generally, on the approach of light, the hood closes up. At first it 

 did no even on the shade of the hand passing its glass. 



The pole colour of the hood is diversified on either side by a dark 

 brown Mripe, arranged in two trapezoidal figures, and others of imperfect 

 formation. 



This animal is exceedingly rare. 



This specimen is rooted on a Tulmlaria inditisa, near the bottom of 

 the stalk. The Tu/ndaria, to judge of the size and quality of numerous 

 parasite*, must be of considerable age, that is, at least several years. It 

 has a fine flourishing head or coronal. Several minute Serin/aria- grow 

 on the hood itself. 



The feelers are cylindrical, consisting of several articulations of nine 

 or ten divisions, projecting without the hood, and perhaps several within 

 it. The whole are beset with slender spines ; the longest are round the 

 articulation*. The extremity of the feeler is environed by about five 

 spines, advancing considerably beyond it.

On the rocks east of Portobello, in the Firth of Forth, this animal is 

 in uncommon profusion. These rocks are almost entirely destitute of all 

 vegetation, nor is there any appearance of it on the shore. But, not far 

 distant, are other rocks, on which are marine plants. The shells of 

 these animals are conglomerated and arranged more irregularly on the 

 surface of the lower part of the rocks, which are not dry probably before 

 about half tide.
