" Based largely on the data of Goodwin and Strain; where there is disagreement between them, data of both 

 workers are given, separated by a diagonal line-to the left for the former, to the right for the latter. 



' The minor pigments neofucoxanthin A and B, neodiadinoxanthin, neodinoxanthin, and neoperidinin are not 

 listed here, nor is oscillaxanthin. 



' No information exists on the plastid pigments of t he Chloromonadophyta (Chloromonadineae). 



^ Only one species without )3-carotene Vxiovin—Phycodrys sinuosa. 



' Two "myxoxanthin-" ( = echinenone-) like pigments. 



'Not recorded by Goodwin through misprint. 



» Probably zeaxanthin, but closely similar diatoxanthin not definitely ruled out. 



* Several kinds of both types of bili-proteins are known; certain of the.se appear to be group specific, but further 

 work is needed to clarify the over-all distribution.
