1 specimen. 

 Adhering to stones and dead shells. Several from 93-77 were upon 

 living shells of Aporrhais pes-pelecani, the dead shells used were usually 

 Modiola modiolus and Psammobia ferrcensis, etc. In confinement this 

 species displays much restlessness, detach themselves and roll about 

 the vessel or tank, re-attach and again loosen, and so on, also as Gosse 

 observes (p. 222), " very protean in shape," and frequently assumes the 

 shape shown in Gosse's figure (PI. VIII). 



Colours very variable ; the column is always smooth, and has a satiny 

 lustre, the crimson or yellowish white predominating according to the 

 individual. Disk dull red or white, streaked with red ; lips usually 

 crimson ; throat dull white or pink. In some specimens a circle of dull 

 spots upon the inner third of the disk. Q^^sophageal grooves, two, red. 

 The pedal disk is frequently flecked and streaked with red of con- 

 siderable intensity ; this is probably corellated with the habit of living 

 for varying periods unattached, lying on the side on hard rocky ground 

 such as it favours. The tentacles pellucid white, with one or two bright 

 red rings, or only one ring near the tip ; sometimes the rings are in- 

 distinct or a white ring below the red ones. Eed lines frequently run 

 down the sides of the tentacles on to the disk. In some also a white 

 spot is present at the base of each tentacle of the two inner cycles, 

 thus forming two alternate circles of white spots. In several, from 

 XCIII. 90, the column and disk were very pale and almost transparent, 

 but the tentacles and throat were red. 



It was noticeable that when a series of stations was worked at 

 intervals away from the coast (Northumberland), the colours of this 

 species became more and more faint, until the column was so trans- 

 parent that the mesenteries could be counted with ease.
