Microcladia borealis Rupr. 



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

 Sound (4). 



The plant \vas not collected in Alaskan waters.

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

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

Family GLOIOSIPHONIACEy^. 



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) ; Vakutat Bay 

 (201) ; Shumagin Islands (372). 



Not common at any of the stations. 



Gloiosiphonia calif ornica (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 

 Nemasto77ia 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 GRA TL O UPIA CE^E. 



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.

Dumontia filiformis (Lyngb.) Ag. 



Abundant in the sublittoral zone in protected places from Prince 

 William Sound northward and westward. Prince William Sound
