OPHIOTHRYCID.S: 



1 6. Ophiothrix fragi/is, Abilg. 



Species with five very spiny arms, and 

 one in which the variation in colouring is 

 absolutely infinite. The most usual colours 

 are white, salmon, pink, red, sage-green, 

 grey, brown, etc. When handled alive 

 they readily detach fragments of the arms, 

 so that it is almost impossible to secure a 

 complete specimen. When however the 

 fishermen's nets are hung up to dry and 

 the brittle stars are allowed to dry un- 

 handled they may be taken in perfect con- 

 dition, the arms displaying every possible 

 curve and contortion. They are known 

 by the fishermen as ' castle cats.' Not a 

 shore species. Hastings.
