NO. 1 TAYLOR: PACIFIC MARINE ALGAE 217 



traversed with delicate somewhat refractive fibers about 1.5 /u, diam., and 

 a cortex of two cell layers, the inner loose, of rounded very thin-walled 

 cells 70-175 /x diam. in surface view, the outer assimilative layer of cells 

 irregularly rounded in surface view, 6-9 fi diam., with conspicuous walls 

 between and a moderately thick jelly layer outside; tetrasporangia scat- 

 tered, formed in the inner cortex, oval, 28-32 fi long, 21-25 ^i diam.; 

 cystocarps abundant, to 1-2 mm diam., moderately projecting, eventually 

 rupturing the cortex to develop an ostiole on one or both faces of the 

 blade, the small spores in irregular masses with much sterile tissue be- 

 tween.

GALLOPHYLLIS Kutzing, 1843 



Plants fleshy membranous, flat, dichotomous, laciniate or pinnate; 

 structurally showing an inner medullaiy parenchyma of large cells in 

 some species intermixed with short rhizoidal ones, and a cortex of short 

 indefinite anticlinal rows of small rounded cells; sporangia tetrapartite, 

 scattered in the cortex; carpogenic branches single on the supporting 

 auxiliary cell, the other lateral cells remaining sterile; cystocarps im- 

 mersed, with the carpospores formed in small groups among medullary 

 cells and more or less compressed nutritive filaments, discharging through 

 one or more pores. 



KEY TO SPECIES 



1. Freely branched ; margin sparingly dentate .... C. violacea 



2. Sparingly branched ; margin entire C. ligulata

The material was scanty and the genus difficult ; some pieces appear to 

 be rather coarse for the species to which they are assigned.
