Kutz. referring to Harvey's view. Collins does not give any 

 account on it in Green Algae of North America. But the length 

 of cells in the present species is generally 2-3 times as long as 

 diameter, and about 5 times before the division, and in no 

 case as half short as, or nearly equal as diameter. C. gracilis 

 Kutz. ma} T come rather near to the present species in the 

 measurements. But it is defined to be a flaccid plant. I choose 

 to mention this species as a valid, until the identity between 

 it and C. tortuosa Kutz., or the affinity- between it and C. 

 gracilis Kutz., has been more positively studied. 



Kjellmax identified a Chaetomorpha, which he has collect- 

 ed on Bearing Islands, with Conferva cannabina Aresch. 

 The specimen kept in the Botanical Museum of Upsala has 

 thicker filaments than Areschoug's co-type found there with 

 it, and the cells are 1^-5 times as long as diameter. Kjelxmax 

 noted the dark green colour of the Behring Island specimen. I 

 think his specimen ma}' be more safeh' identified with the 

 present species than with Areschoug's. 



Locality. Hidaka Prov., epiphytic on Rhodomela Larix, 

 forming large masses of entangled filaments in a manner as 

 shown in Kutzing's Tab. Phyc. Ill, Taf. 50. under Spongopsis 

 mediterranea. 



Distribution. Unalaska; Vancouver Island ; Behring Islands.
