 litoralzone. Esquimalt, B. C, Harvey (1862, p. 175) ; Whidbey

 of the plant from Whidbey Island. 



Ceramium Californicum J. Agardh. 



On algfe in the upper sublitoral zone. Esquimalt and Point 

 Roberts, B. C, Harvey (1862, p. 175, under Ceramium dia- 

 phanum); west coast of Whidbey Island, Wash., K.L.G., Nos.

We bave not seen Harvey's plants, but refer them here because 

 the rest of the west coast C. diaplianum has been placed under 

 this species. The Whidbey Island specimens are typical and 

 show cystocarps, tetrasporangia, and antberidia.

This species is fairly common on the shores of the Bay of 

 Unalaska, but was not found, nor is it reported, from any of the 

 shores until the region of Puget Sound is reached. It is common 

 along the coast of Oregon and on that of California down to the 

 neighborhood of Point Conception.
