Most nearly allied to S. mitreformis, 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 or ACTINIA, FROM THE 
Soutu Coast or Devon. By E. W. H. Hotpsworts. 
(Radiata, Pl. 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 de. ean- 
dida of Mr. Gosse, and J am indebted to that gentleman for his ready 
assistance in determining the differences between them. de. candida 
may be distinguished by its possessing fewer tentacles, by the colour
