liniana (Menegliiiii) Xtvoeli which foniied soft g-elatinous masses 

 of the color of prune jelly on cliffs near Iliuliuk, Unalaska, Alaska 

 {W.A.8. and A.A.L., No. 4032!) and two others, not readily 

 placed, viz., one forming- yellow green soft gelatinous patches 

 on mosses at Sitka, Alaska ( 1^.a4.^^ and A.A.L., No. 5206!) 

 and the other found on a dripping water pipe at Seattle, Wash., 

 {X.L.G., No. 394!). 



Sphaerella nivalis (Bauer) Sommerfelt. 



On banks of snow and where snow is melting. Unalaska, 

 Alaska. ir.A.S. and A.A.L., No. 4048! ; Yakutat Bay, Alaska, 

 Saunders (1901, p. 409). 



The so-called red snow is not uncommon in the mountains and 

 even along the shores of the territory included in this paper, but 

 no careful study has been made as to the presence of this species 

 in one or another form. It has seemed best, therefore, to report 

 only these two localities which are represented by actual speci- 

 mens of the algae concerned. 



Eudorina elegans Ehrenberg. 



Mixed with various confervoid species. Bog Lake, west side 

 of Whidbey Island, Wash., N.L.G., No. 456! 



Volvox aureus Ehrenberg. 



Intermingled with Spirogyra filaments. Near Coupeville, 

 Whidbey Island, Wash., X.L.G., No. 661! 



The material of this species was placed in formalin solution 

 and could not be studied in the living condition. The colonies 

 measure about 200 h- in diameter and the cells are 4-6 /^ broad. 

 Consequently, the specimens have been referred to this species 

 rather than to T'. glohator (L.) Ehrenberg. 



Family TETRASPORACE^E. 



Tetraspora bullosa (Roth) Agardh. 



In small ditches of running fresh water. Seattle, Wash., 

 N.L.G., Nos. 381!, 388!
