great help in determining the young forms and Fragments sold in 

 the markets. 



Someday when algicultiire receives the attention it merits this 

 paper of Prof. Setchell's will be found to have considerable economic 

 importance. Some of the more important limu are given below: 



Aalaula [Codium Muelleri Kuetz.) is said to be a favorite in 

 Honolulu; it must be eaten fresh. 



Akiaki {AJinfeldtia Polyides Aresch.) is commonly eaten in the 

 Island of Hawaii. 



Limu eleele {Enterornorpha intestinalis (L.) Link) is "the most 

 sought after and the best known" limu. 



Huluhuluwaena {Grateloiipia filicina (Wulf.) Ag.) is eaten only 

 on the Island of Hawaii; it is aicoarse, black and hairlike seaweed 

 having a pleasant flavor even to one unaccustomed to eating limu. 

 It is eaten with the opihi limpet. 



Limu huna {Hypnea nidifica J. Ag.) is stewed with meat. 



Limu kala {Sargassum echinocarpiini J. Ag. , Tiirhinaria ornata 

 J. Ag. and probably others of the Sargassum tribe) is said to be 

 eaten but is chiefly employed in ceremonies of purification and 

 atonement. 



Limu kohu {Asparagopsis Sanfordiana Harv.) is sold in the fish 

 markets of Honolulu in balls about 8 cm. diam. composed of fronds 

 mixed with salt and compacted together. It is a "one year limu" that 

 keep indefinitely and is eaten with fresh fish. 



Lipoa {Dictiota dichotonia (Huds.) Lamx, and Halisevis plagio- 

 graninia Mont.). Prof. Setchell saw a small bunch of this limu given 

 with every three flying fish sold in the fish market of Honolulu. It 

 has an odor like very strong parsley. "This is an especially esteemed 

 species and much sought after." 



Lipuupuu [Dictiospheria favulosa (Mert.) Decais.), sold in the 

 Honolulu fish market. 



Manauwea {GracHaria coronopifolia?) is a "one da}^ limu" to be 

 eaten with fresh squid but not with salt squid. "If it is boiled it 

 dissolves, but on cooling it becomes solid again."' 



Oolu (Lanrencia ohtiisa var. racenwsa Kuetz.?) is a favorite limu 

 about Honolulu but the masses on sale in the fish market were so 

 soft and discolored that it could not be determined. Laurencias are 

 much in favor as an article of food , when young they have a slightl}»" 

 pepper}^ flavor. Several other names are applied to species of Lan- 

 rencia such as koko, lipalu, lipeepee, maneoneo, etc. 



Pakaiea {Ulva fasciata Delile and probably any broad JJlva or 

 Monostroma) a well known seaweed said to be edible if properly 

 prepared. 



Poha {Hydroclathrns cancellatns Bor}'-) is said by Miss Tilden 

 (Am. Alg. n. 436) to be "eaten raw by the natives." 



Mualea, a limu said to grow near Ha na on the Island of 

 Maui is reported to be very poisonous. Prof. Setchell saw no spe- 

 cimens. W. T. Swingle.
