Egregia Menziesii (Turner) Aresehoug. 



On rocks, lower litoral and upper sublitoral zones. Nootka 

 Sound. Vancouver Island. B. C, Menzies (Turner, 1808, p. 57, 

 pi. 27. under Fucks Menziesii); Port Renfrew, B. C, Butler and 

 Polky. Xo. 72: Esquimalt, B. C, Harvey (1862, p. 164, under 

 Phyllospora Menziesii); Victoria, B. C, Tilden, No. 236! ; Puget 

 Sound, Bailey and Harvey (1862, p. 160); west coast of Whidbey 

 Island , Wash . , • N.L. G. , No . 48 ! 



These localities probably mark the northern limit of this 

 species. Hence it ranges south to the neighborhood of Point 

 Conception, below which its place is taken by E. lavigata 

 Setchell. 



Pterygophora Californica Ruprecht. 



On rocks, upper litoral zone. Port Renfrew, B. C, Tilden, 

 No. -320!. MacMillan (1902a. p. 726); west coast of Whidbey 

 Island. Wash.. X.L.G.. No. 70! 



Tbis species seems to be abundant on exposed coasts on 

 Puget Sound and reaches a considerable size, as indicated by 

 MacMillan. Specimens fully as large, however, have been col- 

 lected at Duxbury Reef in Marin County, at Carmel Bay in 

 Monterey County, and at San Pedro in Los Angeles County, 

 California. It seems, therefore, that MacMillan's assumption that 

 Pterygophora reaches its maximum development along the Brit- 

 ish Columbian coast can hardly be substantiated. As to the 

 relationship of the genus, we cannot hold with MacMillan that it 

 may belong either to the "Laminariea? or the Alariidea?," but 

 must perforce belong to the latter because of the method of 

 formation of the sporophylls. The possession of rings in the 

 stipe and the hapteres and the fact that the soi'i do not cover the 

 sporophylls completely, seems to us of little importance in this 

 matter, since in undoubted species of Alaria, there may be rings 

 in the stipe, at , east, and in many cases, the sori do not cover 

 the sporophylls completely. In Pterygophora the sporophylls 

 are less determinate in their growth, but this is only of generic 

 importance. We find ourselves in agreement with MacMillan as 

 to the absence of mucilage ducts in the stipe and the presence of 

 large ones in the blade.
