204 SAUNDERS [44] 



Microcladia borealis Rupr. 



In the littoral zone, attached to rocks in exposed places, Puget 

 Sound (4). 



The plant was not collected in Alaskan waters. 



Rhodochorton rothii (Turton) Naegeli. 



Forming a dense coating on rocks, especially in caverns in the upper 

 sublittoral or littoral zones, Prince William Sound (292). 



The writer has collected this plant also on the central California 

 coast and in Puget Sound. 



Family GL OIOSIPHONIA CE^. 



Gloiopeltis furcata (P. & R.) J. Ag. 



Attached to rocks in the sublittoral zone from Puget Sound to the 

 Shumagin Islands. Annette Island (26) ; Sitka (124) ; Yakutat Bay 

 (201) ; Shumagin Islands (372). 



Not common at any of the stations. 



Gloiosiphonia californica (Farl.) J. Ag. 



In the sublittoral region in a protected cove, Prince William Sound 



(277)- 



This species was originally described by Dr. Farlow from the cen- 

 tral California coast. He placed it somewhat questionably in the genus 

 Nemastoma on account of having only dry material for examination. 

 J. Agardh, in Till Algernes Systematik, transferred the species to 



Gloiosiphonia. Dr. Farlow recently stated that since the publication 

 of the species he had examined both living and alcoholic material and 

 believed that Agardh was right in placing it in Gloiosiphonia. 



Family GRATLOUPIACE^. 



Cryptonemia obovata ? J. Ag. 



Washed ashore, Prince William Sound (276). 



Two sterile specimens of a Cryptonemia are referred somewhat 

 questionably to this species. They agree in shape and structure with 

 fruiting specimens collected in Puget Sound which undoubtedly be- 

 long to this species. 



Family D UMONTIA CE^E. 



Dumontia filiformis (Lyngb. ) Ag. 



Abundant in the sublittoral zone in protected places from Prince 

 William Sound northward and westward. Prince William Sound 

 (307, 280); Cook Inlet (411); Kukak Bay (340); Shumagin 

 Islands (365).
