218 ANTIIOZOA IIELIANTHOIDA. 



" Body semi-pellucid white, longitudinally ribbed with an opake 

 and positive white line traversing each rib from the oral aperture to 

 the base : three rows of minute white tubercles on the oral disc 

 externally : four rows of filiform and transparent tentacula, barred, 

 having opake white patches anteriorly : oral disc crossed by ribs 

 equally strong in outline and marking as those on the body : mouth 

 round : lips pouting and dotted with a bright chrome or yellow 

 colour : height when expanded -|ths of an inch ; diameter i of an 

 inch. When contracted it had the appearance of a rough wart, and 

 it felt like one." W. P. Cocks.

"Diam. of the base 1 inch : height | inch to 5| inches. Presents, 

 by turns, the two extremes of the greatest cylindrical length I have 

 ever seen in any Actinia, and the most abject flatness. The former 

 state (Fig. 48) is constant at night, and may be induced by artificial 

 darkness in an hour or two. In the contracted form the tentacula 

 are rarely visible, and always inconspicuous : they are about 50 in 

 number, about 1| inch, and nearly of equal length, extremely slender 

 and snake-like, each being bent ordinarily in two or three irregular 

 curves, and, on being shaken, presenting a frizzled appearance. 

 They are placed in three or four alternating tiers, near the margin, 

 leaving a considerable bare space surrounding the mouth, which 

 last is much crumpled, as in Act. dianthus, to which, however, the 

 tout - ensemble of the animal presents a marked contrast. The 

 lengthened form accords with its habits. The two individuals I 

 found were attached (to a stone, probably) at the depth of about five 

 inches below the sand, on the south side of the stepping stones at 

 Garth Ferry, on the Bangor side. 



" The texture of the body is dense and opake : the colour between 

 flesh and fawn, sometimes with an orange tinge, with well-marked 

 stripes of pale bufi^, alternately broader and narrower ; peristome or 

 space round the mouth, elegantly striated dark brown and buff": 

 mouth coarsely striped, pale brown and buff".
