Dublin, are all except one, Cymathere tripUcata ; and the excepted 

 one is an incomplete specimen, which Setchell^) has identified 

 with Pleur ophy eus Gardneri Setch. 



De Toni^) states that Anderson reported the present species 

 from the Californian coast, but this statement has been apparently 

 discredited by Saunders. 



A specimen of the present species is found in the Agardhian 

 Herbarium at Lund bearing the name A. striata J. Ag. This 

 specific name originates undoubtedly from the fine striations on 

 the matured blades. J. Agardh onco brought A, marginata P. et 

 Pi. under A. csculenta^) but afterward discarded this view.*) 



Setchell^) stated, after he had seen the original of A. margi- 

 nata P. et E-. in Petrograd, that the plant he and Gardner referred 

 to A. prcdonga is really to be placed under A. marginata P. et P., 

 and also that the plant distributed in the Phyc. Bor.- Amer., No. 

 XLIV under the doubtful name of A. lanc2olata, should be referred 

 to the same species. He further expressed the view that A. margl- 

 mita P. et E. may probably replace both the names of A. prœJonga 

 Kjellm. and A. laticosta Kjellm. On examining the originals of 

 tliese two species at Upsala, I could by no means agree with 

 his view. The specimen in the Phyc. Bor. -Amer., in a copy I 

 have seen, was surely not of A. marginata P. et E. as noted under 

 the preceding species. There must have liecn some non-uniformity 

 in the exsiccatœ. 



A close affinity between A. cnrtlpes Saunders and A. prcelonga 

 Kjellm. has already been pointed out by Saunders himself.^)
