252 HISTORY OF BRITISH ZOOPHYTES.

 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 Cum braes, and they quite 

 answered the descriptions given as to size and diversity of 

 beautiful colouring. In Italy and the south of France, " ils
