divifion,unlefs tenwjjlmus and pcdunculatus. It is eafily diftinguifhed 

 from the firft, by its pedunculated tubercles, from the branches 

 having a fubalternate mode of growth, and by the colour. It 

 differs from the fecond, by being very much branched, by the (hapc 

 of the tubercles, which alternate with the fetaceous famuli, and by 

 the colour. 



The whole plant is bright-red and pellucid. The tubercles, when 

 filled with ripe feeds, are darker than the reft. The fetaceous ra- 

 mult, which are twice and fometimes thrice as long as the tubercles 

 with their peduncles, are fo delicate, that the terminations are 

 fcarcely to be diftmguifhed by the naked eye. 



It adheres by fmall fibres to the ftones and pebbles at Cromer ; 

 and has been found amongft other rejectamenta on the fandy fhore 

 at North Yarmouth.
