Alaria esculenta (L.) Greville. 



Arctic Coast of Alaska, Ihin'fij (1S72, p. 4(5:}); from Kaintschatka 



to Sitka, Alaska, PonieU and Buprechf, (1840, j). 11 ). 



The references (|u<)ted refer t(» this species in the old u(Mici-al 

 sense before the majority of the species at present descril)c(l under 

 the j^-enns had been proposed, or, at least, accepted. In all 

 l)robability l)oth these references include several, or, at least, 

 other species than .4. fsciihiifd. Wc have been incliucd to be 

 conservative in reckoning specific distinctions in this gvnus, but 

 find that we must present a very tentative enumeration. Professor 

 Kjellman has very kindly named a selected series of specimens 

 sent to him and we have used his suggestions and notes, even 

 farther than it is possible to state in each particular case. 



Alaria Pylaii (Bory) (Treville. 



On stones in the lower litoral and upper sublitoral zones. 

 Karlnk, Kadiak Island, Alaska, ir.A.*S'., No. oOTo!-. Orcci, 

 Alaska, TV^A.N. (IikI A.A.L., 5153! ; Esquimalt, B. C, Harvei/ 

 (1862, p. 165). 



Kjellman is inclined to refer lioth the Alaskan numbers quoted 

 above, to this species as represented l)y Greenland specimens and 

 they certainly agree with specimens from Elaine which we are 

 disposed to refer to this species. Harvey's specimens are said 

 by Saunders (1901, p. 425) to have been compared liy Kjellman 

 to the A. fragilis Saunders, which, in turn, seems to us to l)e 

 little more than a young, long-stiped form of this species. 



Alaria dolichorhachis Kjellman. 



Agattu Island, Alaska, Toinisend, No. 5753! 



Two specimens, collected at the above mentioned locality, are 

 said by Kjellman, to be near to this species, but still to be sc])- 

 arated from it in all prol)ability, while the s])ecimens referred 

 by one of us (Setchell. in Collins, Ilolden and Setclidl. P. B.-A.. 

 No. XLI) dou])tfully to this species are referred by him to A. 

 lanceolata Kjellman. 



Alaria tenuifolia Setchell. 



Setchell, in Collins, Holden and Setchell. P. B.-A.. No. 

 XLV, 1901.
