ALG^. 



Determined by Dr. W. G. Farlow. 



1. D'Urvill^a utilis, Borij. 



2. D'Urvill^a Harveyi, HooTc. 



Two large specimens of what seems to be this species were brought 

 home by Dr. Kidder. In the Flora Antarctica, the only species of 

 jyjjri-illcea mentioned as found in Kerguelen's Land is D. utilis, but, in 

 the two specimens abov^e mentioned, the perforations of the root corre- 

 spond clearly to the description giv^en of D. Harveyi. 



3. Desmarestia viridis, Lam. x.l — Ajiparently very common. 



4. Macrocystis pyrifera, Ag. — Partly of the typical form, partly 

 the var. luxurians of the Flora Antarctica. 



5. Adenooystis Lessonii, R. cD K. 



6. Sphacelaria funicularis, Mont, f — Quite a number of speci- 

 mens, too small for accurate determination, probably belong to this 

 species.

 was collected by Dr. Kidder. This species is new to Kerguelen's Land, 

 the nearest recorded station being the Auckland Islands. 



8. Dasya (Polysiphonia, R. & R.) Berkleyi, Ag. — Apparently 

 very common.
