PLATE XL. 



ACTINIA CRASSICORNIS, p. 226, of the natural size. The 

 drawing- was made from two beautiful specimens which 

 had selected the Modiola vulgaris for their site : one 

 was of a uniform bright scarlet colour, and the other 

 was cream-coloured and of unspotted purity. The 

 contrast they formed with each other, and with the 

 dark shell, was very striking.
