Vol. Xmi., Art. 1.— K. Yendo; 



unique peculiarity has been passed over by Scheadek. The re- 

 semblance of the species to A. prœlonga Kjellm. is in the texture 

 of the blade and in the mode of the midrib, on which, however, 

 much specific importance should not be laid. The older part of 

 the blade is finely striated in the same manner as in A. marginata. 

 Locality. Port San Juan, Vancouver Island (Schkader) ; Lands 

 End, San Francisco (Setchell).
