Mr. E. W. H. Holdsworth on two new species of Actinia. 347 



contracted ; tentacula iu four rows, moderately long, slender, and 

 slightly tapering towards the tips, their length regularly diminishing 

 from those of the inner circle outwards. The entire animal has a 

 pale transparent appearance, and the only trace of decided colour 

 about it is found in a narrow dark blue line surrounding the base of 

 each tentaculum, and extending a little in the direction of the mouth, 

 but soon becoming indistinct. Very delicate white luies are at times 

 visible on the surface of the body, but these are probably only the 

 edges of the membranous septa seen through the transparent skin. 

 When this animal is at all roughly handled, the long seminal fila- 

 ments are thrown out from the mouth in great profusion. This 

 little Anemone approaches very closely in many respects the Act. Can- 

 dida of Mr. Uosse, and I am indebted to that gentleman for his ready 

 assistance in determining the differences between them. Act. Candida 

 may be distinguished by its possessing fewer tentacles, by the colour 

 of the body being of a more opake white, and especially by the narrow 

 lines surrounding each tentaculum being of a reddish-purple tint, and 

 enlarging into a conspicuous spot on each side of its base. In their 

 habits and general appearance they are very much alike, and had I 

 obtained only one example of the pale species, I should hardly have 

 ventured to consider it more than a variety. Ten specimens, how- 

 ever, were taken from diiferent places, and did not vary except in 

 size ; they were found on the exposed surface of perpendicular rocks 

 at about half-tide mark, and when out of the water and contracted, 

 were very difficult to distinguish, owing to their great transparency. 

 I propose for this species the name o( pallida. 



It has been my custom, after any expeditions in search of ActinicB, 

 to bring home one or two plants of Laminaria digitata, iu order to 

 examine at my leisure the various forms of animal life commonly met 

 with among their tangled roots ; and it was on one of these plants I 

 found, in company with minute Ophiocomce, green Nereides and 

 numerous other animals, the beautifully marked Anemone that I have 

 now to describe. 



It has the following characters : — 



Body elongate, cylindrical, about three-quarters of an inch in length 

 when extended, the upper half covered with numerous pale perforated 

 warts, increasing in number as they approach the top, and from 

 which the white filaments are protruded when the animal is irritated. 

 Tentacula in five rows. Colour of the body a dark orange, becoming 

 paler towards the base. This species is chiefly remarkable for the 

 beauty of its oral disk, which for colouring and elegance of marking 

 will bear comparison with that of any of the larger kinds. The external 

 half of the disk is of a rich purplish-brown, changing into a light 

 orange tint towards the mouth, the pink tumid lips of which are 

 frequently conspicuous ; from near the centre diverge ten or twelve 

 pairs of yellow bands slightly separating as they proceed outwards, 

 and at their extremities partially surrounding the bases of the tenta- 

 cula, according to the following arrangement. Taking a small seg- 

 ment of the disk, the first tentacle may be said to arise from the 

 space between two pairs of bands, the second being situated witliiu
