191-i] Setchell: The Scinaia AsscmhJage 113 



moniliform anticlinal rows of colored cells with oval utricles at two 

 or three different heights ; corticating layer averaging about 100^ thick, 

 dense in older parts, of interwoven slencler thick-walled filaments, often 

 very nearly filling the entire cavity between axis and cortex; mono- 

 ecious; antheridia single on slender stalk cells, over the entire surface; 

 cystocarps obpyriform. like those of Scinaia, with thick pseudo- 

 parenchymatous periderm. 



The description of this species must necessarily remain imperfect 

 since only a small fragment of a specimen presumably of this species 

 has been available for study. This specimen is in Herb. Farlow and 

 was collected at the Bay of Islands, New Zealand, by Berggren. It 

 was identified as Scinaia furcellafa by J. G. Agardh (1877, p. 26). 

 The specimen is clearly a Gloiophloea and answers to Agardh 's descrip- 

 tion. It is monoecious as I suspect from Agardh 's figures the species is, 

 since his figure 5 (1879) represents a very young cystocarp with what 

 I interpret as an antheridial branchlet (fig. oil) on each side of it. It 

 is to be compared then with Gloiophloea Okamurai from Japan and 

 other monoecious species, which are less branched and darker as well 

 as more rigid. I have been able to examine an abundance of antheridia 

 but only a few very young cystocarps in the New Zealand specimen. 

 Consequently the description of the cystocarp must remain incom- 

 plete. Agardh 's figure of the cystocarp (1879, fig. 4) is manifestly 

 imperfect and represents the periderm as filamentous ( ?). The young 

 cystocarps of the New Zealand specimens show a pseudoparenchy- 

 matous periderm. Agardh 's type was one of the specimens distributed 

 by Harvey under No. 348 of his Australian algae and comes from 

 "Western Port near ^Melbourne.
