362 HISTORY OF BRITISH ZOOPHYTES. 



Genus XIX. SALICORNAEIA, Cuvier, 

 Gen. Char. Polypidoms plant-like, calcareous, dichotomous ; 

 the branches cylindrical, regularly jointed, with immersed rhom- 

 boidal cells diverging from the axis, disposed in quincunx, and 

 opening on the surface ; the aperture lateral, transverse, some- 

 what labiate. — Br. Johnston.

Dr. Johnson says, with great truth, ''one of the finest 

 of British zoophytes." Fine specimens are three inches in 

 height. Ellis, who figures and describes it, calls it the 

 "Bugle Coralline." ''This beautiful stony coralline pro- 

 ceeds from transparent membranaceous tubes which enter 

 into and form cylindrical joints, composed of stony lozenge- 

 shaped cells, with a proper entrance into each : these sur- 

 round the whole surface of the coralline." The joints which 

 connect the different parts of the dichotomous branches are 

 of the same substance as the fibres from which they spring ; 

 being elastic and pliable, the polypidom sustains no injury 

 from the agitation of the sea. The joints are often blackish.
