Endocladia muricata t. compressa Setehell and (Taidner 

 f. nov. 



Cylindrical below, but decidedly flattened above. Otherwise 

 as in the typical form. 



In rock pools near high water mark. Friday Harl)()r, San 

 Juan Island, Wash., X.L.G., No. 216! 



This may possibly be the E. rompUtuatu Harvey from Japan, 

 but as we have not seen a specimen of that species and, as it is 

 described as decompositely dichotomons which ours certainly is 

 not, we feel that this may be left with only a form name. 

 F. compressa seems to be a plant of quiet waters while the type 

 grows on exposed coasts. 



Endocladia muricata f . inermis Setchell and Gardner f. nov. 



A dwarf plant almost or quite destitute of s])ines. 



In small tide i)ools at high-water mark, much exposed to sun 

 and rain. Friday Harbor, San Juan Island, Wash., X. L.G.I 



A very distinct form growing in short densely interlaced rigid 

 tufts, and striking on account of its smooth or very nearly smooth 

 frond. 



Chondrus crispus (L.) Lyngbye. 



On rocks in the litoral zone. St. Lawrence Island, Alaska, 

 Kjellman (1889. p. 32. under C. phitytnis) ■ St. Michael. Alaska, 

 Herb. B. C. Eaton. No. 14!, under C. plaiijnus, W.A.S., Nos. 

 5154x!, 5246y! ; St. Paul Island, Alaska, Greeley and Snodgrass,

After a careful study of the forms of Chondrus of both sides 

 of the North American continent from the living specimens and 

 a careful comparison of such European specimens as are avail- 

 able, together with such descriptions, critical notes and figures 

 as have been published, it seems to us that the species described 

 from our territory are better understood if placed under C. crispus 

 and its various forms. It seems to us that No. 4034a, which 

 shows young cystocarps and agrees in lial)it with Kjellman's
