SEA-ANEMONES. 71 



near the summit. The disk is variable in colour, and indefi- 

 nite in detail ; but in general effect it is a minute patchwork 

 of black, brown, and yellowish-drab lines radiating from the 

 whitish mouth, and minutely dotted with white. From each 

 angle of the mouth there is a very distinct, short, opaque white 

 line. The tentacles are numerous, and variable in length ; 

 their ground colour is a clear grey, with several cross bands of 

 white, and at the base there are two small patches of white 

 surrounded by black in such fashion as to form an obscure B. 

 This is a pretty constant mark in the identification of the 

 species, though the white patches are sometimes missing. 



The Cave-dweller, though not easily seen at first, is widely 

 distributed upon our shores, whether rocky or sandy, and 

 careful examination of the pools on hands and knees will 

 probably reveal large numbers. Occasionally we shall come 

 upon a cleanly-hollowed basin in the rocks, about two feet 

 across and almost as deep, the interior thickly coated with a 

 dense growth of coralline. In this the Cave-dweller and the 

 Gem Pimplet delight to grow, and in such situations they can 

 be more easily obtained than from the chinks of rock that will 

 not admit the fingers. 



The Daisy Anemone (Cereus pedunculatus] is similar at first 

 sight to the Cave-dweller. Why it was named daisy it is diffi- 

 cult to imagine, for I have seen no specimens that suggested 

 the most remote resemblance to that flower. It is similar to the 

 Cave-dweller both in form and habits, but it is more soberly 

 coloured, the very broad disk being dark-brown or black, 

 crossed by very fine red lines radiating from the mouth and 

 continued along the sides of the tentacles. The brown of the 

 tentacles has a yellowish bias. Near the base of some ten- 

 tacles there are two white bands separated by a patch of 

 brown ; others are uniformly coloured throughout, save for 

 tiny specks of white sprinkled without order over them. The 

 tentacles are very numerous (400 or 500), and mostly small. 

 The Daisy is found in the crevices of pools left by the ebbing 

 tide rather than in those of perpendicular rock-walls.
