FAUNA OF THE ALEUTIAN ISLANDS AND ALASKA PENINSULA 369 



are conspicuous on the Aleutian beaches (fig. 2). Members of 

 the Lithothamnion group form chalk-white crusts around the 

 rhizoids of kelps, these crusts being later washed up on the beach 

 in windrows. Corallina grows in branched tufts on the rocks, 

 looks like an ornamental coral, and is wine colored to dirty white. 

 Its stalks are commonly found attached to pebbles brought up 

 by dredging. 



A list, accompanied by brief field notes, of 40 species of marine 

 algae collected in the Aleutian Islands has been published by 

 Okamura (1933), who stated that "the Aleutian algae are al- 

 most equally dispersed westward to Japan, and eastward to 

 California." 



(The vascular plant Zostera, or eel grass, an important water- 

 fowl food, was observed growing in a lagoon on Vsevidof Island, 

 near Umnak Island, but it was not seen farther west.)
