Of the Tubular Corallines. 



BY Tubular Corallines are meant fuch as are compofed 

 of a Number of fimple Tubes, growing up near togo- 

 ther ; or fuch branch'd ones as are compofed only of Tubes 

 without Denticles or Veficles. Thefe are of the fame horny, 

 elaflic Nature with the former ; and like them recover their 

 original Form, after being fome time dry, by being put into 

 Water : They arife too, like the preceding Clafs, from mi- 

 nute worm-like Tubes ; and widen a little as they advance 

 in Height. Some of them look wrinkled like the Windpipe, 

 and others like the Inteflines of fmall Animals.

Tubulous Coralline wrinkled like the Windpipe. 



This Coralline is found in great Plenty in the Sea, near 

 the Opening of the 'Thames^ adhering to other marine Bodies, 

 and often to the Bottoms ol Ships. I have received it with 

 the Animals alive in Sea-water ; in which State it affords a 

 moft agreeable Scene : The Top of each Tube bearing a 

 bright crimfon-coloured Polype, equal in Richnefs of Colour 

 to the Guernfey Lily ; all the Animals difplaying their Claws 

 or Tentaculi at the fame time, with furprizing Agility.
