far greater and the great triangular plates at the forks were 8 cm on a 

 side, though in other instances hardly so distinct. The specimen no. 509 

 is a small, densely branched thing, but probably only a young growth 

 stage. From Setchell's paper it is evident that the species is exceedingly 

 variable in general shape, although quite distinctive microscopically.

Codium foveolatum Howe, prox. 



Plant coarse but relatively small, the axes to 4-6 cm long, mostly 

 decumbent with secondary attachments to the substratum and other 

 branches, irregularly branched, the branches 3-8 mm diam., cylindrical 

 throughout, when dried distinctly lacunose spongy; peripheral utricles 

 rather truncate rounded, 300-600 /x diam., about 2-4 diameters long, the 

 end wall 5-20 fi thick, the outer surface foveolate-roughened ; hair scars 

 not recognizable; gametangia apparently single on the fertile utricles, 

 somewhat tapering ovoid, 150-190 fi diam., 250-420 fi long. 



Howe 1914, p. 45, pi. 10, text-figs. 15-19. 



These plants are to be compared with C. repens (Crouan) Vickers 

 and C. Geppii Schmidt, but are in general coarser in habit than either of 

 them and the vesicles have notably thicker end walls, with an irregular 

 pattern of sinuous pits. Specimen no. 362A-35 differed from the rest in 

 being slender throughout, barely 3-4 mm, but had the same cell wall 

 structure.
