16' 2 SEAWEEDS. 



Another species that freighted those waves was the 

 ( Jeramium Rubrum, a pretty bright red weed with taper- 

 ing branches, the tips a little curled. 

 It is a common weed, and very 

 variable ; our specimens were four 

 or five inches in length. We found 

 a lovelv small Ceramium afterwards 

 on rocks at Granton, in the Firth 

 of Forth, at nearly low tide mark.

 string of minute oval beads, ruby and white alternating ; 

 the tips were daintily curled in (C. acanthonotum) ; 

 under a magnifying lens you could see three thorns 

 planted outside each tiny branch. There are a great 

 number of species of Ceramium, all very interesting ; 

 some as fine as hair, with hooked tips, and delicately 

 marked articulations. 



The family of Griffithseas is equally beautiful ; more 

 robust in form, but very perishable in texture. The 

 articulations are very plainly marked in this family also. 

 They are named in honour of Mrs Griffiths of Torquay, 

 who did much to facilitate the study of Algology ; they

 the tiny stems were much branched, each branchlet re-
