 tentacula raising themselves scarcely above the level

 without permanently attaching itself.

Colour. Light buff marked with longitudinal band3 

 of lighter colour. Disc whitish-grey, covered with a 

 mealy or speckled pattern. Tentacles grey, with a 

 line of dark brown down each side. A variety, mela- 

 nops, has "a broad, well-defined band of deep black 

 crosi ing the disc and tentacles.'^ 



There are about 200 long, slender, flexible tentacles 

 arranged in five rows. The name '^snake-locked" is 

 very appropriate, as the tentacles are waved carelessly 

 about in all directions, in "irregular snaky curves, the 

 anemone reminding one of a cylindrical monumental 

 figure, surmounted by an abundant collection of ser- 

 pents." 



Genus Y. Adamsia, Forhes. 



Named in honour of Mr. John Adams.
