Plate XLI. fig. 1. 



STEM simple and creeping, or erect and irregularly 

 branched, both stem and branches being composed of 

 several parallel tubes; HYDROTHEC.E long, stout, nar- 

 rowed towards the base, sessile, with a plain aperture, 

 springing from all sides of the stem and branches; GO- 

 NOTHEC^E unknown; POLYPITES of a sulphur-yellow 

 colour. 



Var. a. robust a (Sars). More robust, thickly branched, 

 with more numerous calycles, which are densely crowded 

 together. 



Var. /3. With smaller calycles and a simple stem, which is 

 attached at intervals only to other zoophytes, hanging 

 from them in a festooned fashion. (Alder.} 



Height of erect form from 2 to 4 inches. 



L. DUMOSA is subject to many variations in habit, in the 

 size of the calycles, in the thickness of the compound stem, 

 the amount of branching, &c. In its humbler or dwarf 

 condition it is met with in immense profusion, covering the 

 stems of other zoophytes, running over the surface of sea- 

 weeds, or investing shells and stones with its delicate net- 

 work and tinv tubes.
