the base, ac^rccinn^ also in otlier characters very satisfactoril\' 

 with the referrcnces of the present species. The sjiecimcns from 

 Oga, Shobuta and Nezugaseki stand quite near by the two in 

 general aspect of iVonds and resemble very much to a specimen 

 from South Australia sent from Major Rein'oold under P. can- 

 ccUata Harv.; but the number of pericentral cells often count 8 

 or 9 and the basal parts of frond are always corticated. I can 

 not find an}' other species ever described which applies in other 

 characters so closely to P. canccUata Harv. but corticated. 



I have in my herbarium an authentic specimen of P. cancel- 

 laia Harv. from West Australia. This specimen has the number 

 of pericentral cells 7-9 and not corticated at all. It has hook- 

 form branchlets in the lower parts of frond, a remarkable 

 character as a Polvsiphonia. This peculiarity is not to be found 

 in our specimens nor in that from Major Reinbold. The present 

 determination is not without some uncertainty. As for the cor- 

 ticated specimens, I keep them in doubt under the present species.

My specimen agrees in every respect with the figure in Tab. 

 Phyc, I.e., as well as the originals at Dublin. I have but a 

 dried one. The filaments measure 4-0-4-5/^ in diameter and 70-
