COLOUR NO SPECIFIC MARK. 143 



home a fortnight, I discovered, with great surprise, was 

 changed into an Orange-tentacled — disc and tentacles being 

 of a rich orange hue, the only traces of white remaining 

 just at the tips. If there had been any other specimen in 

 the vase I might have doubted ; but having only one in 

 company with a white Daisy, and a Smooth Anemone, there 

 was no avoiding the conclusion. 



I have had an Anthea, with brilliant green tentacles, turn 

 to a pale grey in the course of two days, and back again to 

 green : and a Weymouth Anemone turn from pearly-white 

 to a soft reddish-bro^vn. In fact the changes of colour, ex- 

 cept in the Crassicornis, which appears to me to retain its 

 hues with tolerable constancy, are far too frequent to admit 

 of colour forming a specific character.
