Hah. Deep water. " Mount's Bay in Cornwall," 3h' Batten. 

 Plentiful on the Devonshire coast, Montagu. Said by Dr Walker 

 to occur in Scotland, Jameson. " I have also received it from Scot- 

 land," Sowerhy. 



Polype-mass more than 12 inches in height, and 15 or 16 in 

 breadth, fixed to rocks by a broad circular fibro-corneous disk, 

 shrub-like, branched from near the base, the branches expanded la- 

 terally, cylindrical, erect or erecto-patent, warty. Axis black, smooth 

 and somewhat glossy, round or a little compressed, compact and cor- 

 neous, with a snow-white pith in the centre, irregularly cellular and 

 very like the pith of a rush ; near the extremities of the branches 

 the axis appears to be a single tube striated longitudinally, but this 

 appeai-ance is produced by drying, for when steeped in water the 

 striae are removed ; it is often bulged or knotted at uncertain inter- 

 vals, but no pores can be detected in its parietes. Crust white, cre- 

 taceous, friable, warted with numerous polype-cells and wrinkled in 

 the small spaces between them ; thickest towards the ends of the 

 branches which it covers over. Cells partly filled with a yellowish fi- 

 brous substance being the remains of the polypes, their orifices clos- 

 ed with eight converging obtuse small segments, one of which is so 

 much larger than the others as to occupy a half or a third of the whole 

 circumference. 



2. G. PLACOMUS, irregularly branched, the branches disposed 

 in a dichotomous order and a Jlattish form, cylindrical, warty ; 

 cells protuberant, conical, surrounded at top by little spines. Ellis.
