Gigartina papillata forma cristata Setchell. 



A single plant of this variety was collected in Kukak Bay (3310) 

 which is apparently identical with Dr. SetchelPs cristata. It is 

 also very closely related to some forms of G. mamillosa. 



Gigartina pacifica Kjellm. 



On rocks in the sublittoral zone. Yakutat Bay (200) ; Prince 

 William Sound (308) ; Shumagin Islands (358, 377). 



No. 377 agrees exactly with Kjellman's figures and descriptions, the 

 others are somewhat intermediate between G. pacifica and G. papil- 

 lata. 



Kalymenia californica Farlow. 



In tide washings, Kukak Bay (342). 



The plant collected in Kukak Bay is much smaller in all of its parts 

 than specimens from the California coast. The proliferations are 

 very numerous, obovate, and only 2-5 cm. long by 1-2 cm. wide. 



Ahnfeldtia plicata (Hudson) Fries. 



On rocks in the sublittoral zone, Yakutat Bay (250) ; Prince Wil- 

 liam Sound (270). 



The specimens collected at both stations were sterile and had fewer 

 and shorter branches than the typical forms but agree in structure. 



Family RHODOPHTLLIDACE^. 



Turnerella mertensiana (P. & Rupr.) Schmitz. 



Washed ashore in exposed places. Kukak Bay (352) ; Shumagin 

 Islands (453). 



The plant is oblong or ovate, fastened to rocks by a basal disk, 

 entire or lobed on the margin, coriaceous, and of a deep dark blood-red 

 color ; several specimens were obtained 6 dec. long by 3 dec. wide. 



This species was seen at only three stations in Alaska, a large spec- 

 imen was seen in the herbarium of Mr. N. L. Gardner, collected in 

 Puget Sound. There is also a small sterile specimen in the writer's 

 herbarium, from the central Californian coast, Monterey Bay. 



Euthora cristata (L.) J. Ag. 



Abundant in the sublittoral zone. Seldovia, near the entrance to 

 Cook Inlet (415) ; Shumagin Islands (356). 



One of the most abundant of the red algae. It is also reported from
