Most nearly allied to S. mitrceformis, Sow., and remarkable for 

 the large size of the varices, which are reflexed, and produced at the 

 shoulder into a semitubular spout. The varical lines make about 

 one revolution from the apex to the base. In the very young shell 

 the varices are not shouldered, and are more numerous. 



3. Description of Two New Species of Actinia, from the 

 South Coast of Devon. By E. W. H. Holdsworth. 



(Radiata, PI. V.) 



Among various species of Actinia collected by me in July last, on 

 the south coast of Devon, two appear to be undescribed, and although 

 of small size, are of some interest in being additions to the fast 

 increasing list of our native zoophytes. 



They were found on the rocks near the entrance to Dartmouth 

 harbour, a part of our western coast, which, from its steep rugged 

 character and its luxuriant growth of sea-weeds, presents a fruitful 

 hunting-ground for those in search of marine productions. 



The first that I have to notice may be thus characterized : — 



Body smooth and cylindrical when fully extended, from half to 

 three-quarters of an inch in height, but very much flattened when 

 contracted ; tentacula in 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 lines 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 Ac. Can- 

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

 assistance in determining the differences between them. Ac. Candida 

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