divifion, unlcfs tenu'ijfiimn and pedunculalus. It is eafily didins^uiflied 

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

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

 differs from thefecond, by being very much branched, by the Ihape 

 of the tubercles, which alternate with the fetaceous ramuli, 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- 

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

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

 fcarcely to be diftinguiflied by the naked eye. 



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

 and has been found amongfl: other rejectamenta on the fandy fhore 

 at North Yarmouth.
