CORALLINA. 221 



scribed as Millepora lichenoides ; while its earlier states consti- 

 tute Lamouroux's various species of Melobesia.* 



Mr J. B. Harvey says — " An intelligent friend, Mr Burnett, 

 lately directed my attention to the very beautiful white light 

 produced by holding pieces of C. officinalis close to the flame of 

 a candle." In making the experiment, the coralline must be 

 held close to the flame but not in it. 



Cor. officinalis was once believed to possess very powerful 

 vermifuge properties. " Corallinee crassiusculae contrita? pulvis 

 in vino, lacte aut cassia exhibitus, pueris ad di'achmam dimidi- 

 am, adultioribus ad drachmam unam interaneorum veraies ene- 

 cat et expellit." Ray. 



2. C. ELONGATA, the lateral shoots of the branches 

 slender and subidate, loith long cylindrical articulations.

Coralline attached by a crustaceous base, rising to the height 

 of three or four inches, very bushy, distinctly jointed, slender, the 

 ultimate branchlets almost hair-like : articulations of the stem 

 not much longer than their own diameter, somewhat compres- 

 sed and wedge-shaped, the shoulders often produced into a spi- 

 rule: articulations of the setiform pinnules cylindrical, from two to 

 six times their diameter in length, often terminated with a grani- 



* Melobesia elegans of Bean is, however, a \evy different thing. 

 I believe it to be a polythalamous zoophyte, and that its right place will 

 be among the Polysomatia of Ehrcnberg. It is described and figured by 

 my friend A. H. Hassall in the Annals of Nat. History for Nov. 1840, 

 p. 173, pi. 7, fig. 2.
