Mr. De la Beche on the habits of Cart/ophi/llia. 483 



presented the same appearances with the exception of agreater elon- 

 gation of the tentacula. One of the brownish red specimens was now 

 dead : the other remained sunk in its cell. The latter being pro- 

 truded in the evening, I presented it with a small piece of the 

 common sand shrimp, which it conveyed into its sac much in the 

 same manner as the green individual did. It, afterwards, pursed 

 up the orifice, which became of a somewhat deep coloured brown 

 pink. 



The green individual was fed with a small piece of shrimp, 

 and exhibited the same mode of feeding as it did before. 



On this day I procured three other individuals : they were all 

 tinted of a brownish red. 



The brownish red individual first captured now seemed to be 

 greatly revived by the food which it had swallowed ; the tenta- 

 cula being expanded, and the animal generally in a plump state : 

 I offered it another piece of shrimp, which it swallowed in the 

 usual way, and became much plumped out, more particularly about 

 the sac, the mouth of which was curiously pursed up. The green 

 individual was also much plumped out. 



The three newly captured individuals were nearly sunk in their 

 cells : each, however, contrived to swallow the little piece of 

 common sand shrimp oifered to it. 



Sharland, the man who procured these corals, told me,that Mrs. 

 .Griffiths found them alive in Tor-bay about three years since : he 

 gave me the following account of their localities and habits. They 

 are always found under large stones, or the under parts of ledges 

 of rock, with their orifices and tentacula downwards. They are 

 only met with at low spring tides, and are usually discovered at 

 the Corbons Rocks, at the end of Tor Abbey Sands. They do 

 not occur in groups, but scattered. 



Jpril 27. The green individual, and the reddish brown one first 

 captured, continued expanded nearly the whole day. Upon pre- 

 senting each of them with a small shrimp, they soon conveyed 

 the shrimps into their respective sacs. The reddish brown one turned 

 its shrimp upon its back by means of its tentacula, before it swal- 

 lowed it : this was, perhaps, accidental, for the green individual 

 swallowed its shrimp sideways, in such a manner that the tail re-
