ACTINIA. 247 



10. Actinia intestinalis, Br, Fleming. 



Hab. Adheres to rocks at low- water mark ; Zetland, 

 Dr. Fleming. 



This bears some resemblance to the former in its com- 

 parative length and breadth, but in many respects it is 

 very different. " When contracted," Dr. Fleming says, ^^ the 

 body seems like two broad rings of nearly equal breadth, 

 and about half an inch in diameter; when expanded to 

 nearly two inches, the body consists of two cylindrical por- 

 tions of different dimensions, smooth, pellucid, yellowish." 

 In Dr. Johnston's figure (49), in its contracted state it is 

 like two joints from the Giant's Causeway laid one above 

 another ; in its expanded state, it is like a telescope when 

 drawn out. 



11. Actinia Cheysanthellum, C, W. Teach. 

 Hab. Coast of Cornwall, Peach. 



This is one of Mr. Peach's numerous discoveries. It is 

 almost white, with six broad stripes and three narrower ones 

 betwixt each of the two broader t)nes, running the whole 

 length of the body, and crossed by narrow transverse ones. 

 The tentacula are twelve. Though found among stones in 

 the sand, it does not attach itself to the stones, but lies 

 buried in the sand with the head above.
