— he is Actinia troglodytes, or "the cave-dweller," 

 so named from a race of African shepherds who 

 lived, like our friend, in caves hollowed by other 

 hands. He is a rarity on the North Devon coast, 

 having been first discovered near Ilfracombe b}^ the 

 author in the summer of 1855, and comparatively few 

 specimens have as yet been found, but he is common 

 at Tenby, in " the caves," where he frequents the 

 company of ^. nivea and his allies (Gosse). Other 

 habitats are Berwick Bay (Johnston), Cornwall 

 (Couch), Isle of Man (Forbes), Moray Firth (Eo- 

 bertson). 



We wend our way further to the westward, and 

 halt under a shelf of rock, to examine three or four 

 narrow pools which lie far back beneath the over-

 Here we find "the daisy" {Actinia hellis), a dark 

 gray anemone, with numerous streaked and mottled 

 tentacles. It dwells in angular cavities, and shrinks 

 far out of sight on the slightest disturbance. It is 

 known chiefly by its flat gray disc and its cup-like 

 body. Chisel it out, then, and put it into one of the 

 smaller bottles. There is a variety of a rich choco- 

 late colour, with an underlying tint of dull crimson. 

 This species generally inhabits shallow, sheltered 

 rock-pools, some few feet above low-water mark. 



See ! the tide has turned, and the sea-fog is

 a capital day's work, for which we may thank, first,
