diversified in colour and aspect. Red is usually predomi- 
nant. The surface of many, however, is variegated red and 
white, like a rose; or with orange-green and yellow inter- 
mixed. One occurred almost totally white, another wholly 
primrose-yellow. It may be truly affirmed that the diver- 
sities baffle enumeration and description.” Dr. Johnston 
remarks, “ It is very sportive in its colours, and some of the 
varieties are eminently beautiful. One is of a bright 
scarlet, studded over with pale warts like ornamental beads ; 
another is of a cream-colour without spot or stain; another 
is of a pale sulphur-yellow, or greenish with orange-coloured 
stripes, the oral disc and vesicular lobes borrowing the hues 
of the wild rose.” In the south of England, according to 
Mr. Cocks, it is occasionally a littoral species, being found 
in the crevices of sheltered rocks. It is not so in the west 
of Scotland, where the only specimens I have seen were 
brought by fishermen from deep water. Major Martin, at 
Ardrossan, has at different times kept for weeks fine spe- 
cimens from deep water off Cumbraes, and they quite 
answered the descriptions given as to size and diversity of 
beautiful colouring. In Italy and the south of France, “ils
