 Wash., X.L.G., No. 284!; Tracyton, Kitsap County, Wash , 

 Tilden, No. 243!, but the last specimen is so poor that it is 

 scarcely determinable. 



Mesogloia simplex Saunders. 



On worn plants of Ghorddria abietina Kuprecht. Sitka. 

 Alaska, Saunders ( 1901, p. 423) ; Gonzales Point, Victoria, B. C, 

 Tilden, No. 348 (fide Saunders, 1901, p. 424); Port Renfrew, 

 B. C, Butler and Policy, No. 9! 



This curious species needs farther study. We have seen only 

 one specimen, communicated to us by Mr. Collins. 



Mesogloia Andersonii Parlow. 



On rocks in the lower litoral or upper sublitoral zone. Port 

 Renfrew, B. C, Butler and Policy, Nos. 12 and 41; west coast of 

 Whidbey Island, Wash., N.L.G., Nos. 116!, 116A!, 468! and 

 in Collins, Holden and Setchell, P. B.-A., No. 92.5! ; San Juan 

 Island, Wash., Tilden. No. 349! , under Ghordaria flagelliformis . 



Tin- plants of this species become very gelatinous very soou 

 after they are taken from the water. Miss Tilden's plant has 

 been referred here by Farlow and represents the typical structure 

 of this species, but in our copy of the American Alga? the habit 

 is dwarfed and somewhat less regularly pinnate than in the more 

 typical specimens. Saunder's " Liebmannia sp." (1901, p. 424, 

 pi. 49) seems to us to belong to this species. His habit-figure 

 resembles the habit of Miss Tilden's plant, while the structure 

 agrees very well with that of the type. It was collected at Sitka, 

 Alaska.
