[44 T ] THE ALG^E 2O5 



The specimens from Cook Inlet bear an abundance of cystocarps ; 

 the others have tetraspores. 



Cryptosiphonia grayana J. Ag. 



In the sublittoral zone. Wrangell (162); Sitka (132); Yakutat 

 Bay (208) ; Kukak Bay (330). 



The Yakutat and Kukak Bay specimens bear cystocarps, the Sitka 

 and Wrangell material tetraspores. 



Dilsea californica (J. Ag.) Schmitz. 



In the sublittoral zone, Orca, Prince William Sound (313). 



The large sterile plants (3-5 dm. long by 1-2 dm. broad) were 

 submitted to Dr. Setchell and were referred by him to this species. 



Dilsea arctica (Kjellm.) 



Attached to rocks in the sublittoral zone, Shumagin Islands (353). 



Young plants are broadly ovate or reniform, and of a light rose-red 

 color, older specimens are once to twice longitudinally divided nearly 

 to the base and of a light faded red color. 



Constantinea rosa-marina (Gmel.) J. Ag. 



In the upper part of the elittoral zone, Prince William Sound 

 (298). 



It was observed at several other stations, including the Shumagin 

 Islands, but no collections were made. It occurs in both protected and 

 exposed situations, but seems to be more abundant in exposed locali- 

 ties. Its occurrence in Puget Sound would indicate a general distri- 

 bution from that locality to Bering Sea. 



Family S% UAMARIA CE^E. 

 Hildenbrandtia rosea Kuetz. 



Forming a very delicate rose-red crust on rocks in the littoral and 

 sublittoral zones, from Puget Sound to the Shumagin Islands. 



The same species is reported by Kjellman from Bering Sea. The 

 writer has also found it common on the central California coast. All 

 specimens were sterile. 



Family CORALLINACE^E. 1 

 Melobesia patens. 



On Amphiroa epiphlegmoides, Prince William Sound (4230). 



Dr. Foslie is somewhat in doubt as to the species, labeling speci- 

 mens submitted to him, " M. patens or n. sp." 



1 Specimens of all Corallinaceae enumerated were sent to Dr. Kjellman who 

 requested Dr. Foslie to work them over. The determinations are entirely those 

 of Dr. Foslie.
