var. major (Bernard) comb. nov. 
KircJineriella major Bernard, Protoce. et Desm. d’eau douce 179. pi. 
14, jigs. 398-399. 1908. 
The blunt apices and general outline of the cells resembles the 
typical form, but the space between the apices is much broader 
and deeper. The resemblance to K. oijesa is so close, however, 
that this alga should be placed as a variety and not a distinct 
species. Schmidle (Flora 78:44 pi. 7, /. 3. 1894) has figured 
a K. ohesa that is identical with this variety. (Plate 10, fig. 7). 
III. Lac Court Oreilles (r). 
Kirchneriella elongata U. M. Smith. 
Bull, Torr. Bot. Cl. 43: 473. pi. 24, /. 7. 1916. 
In the original description of the species I was uncertain 
whether or not a pyrenoid exists. During the past summer 
living material was studied with this point in view and none be¬ 
ing found, the description should be amended to state that no 
pyrenoid is present. 
III. Devils (rr), Lae Court Oreilles (rr). 
Genus ACTINASTRUM Lagerheim 1882. 
Actinastrum hantzschi Lagerheim. 
Ofvers. Kgl. Vet.-Ak, Forh. 39: No. 2; 70. pi. 3, figs. 25-26. 1882. 
Although the occurrence of this alga was noted in the prelim¬ 
inary list the multiple colonies have only been found in Chetek 
Lake. 
III. Chetek (rr). Prairie (rr). 
var. elongatum var. nov. 
Cells 33-37 x 5-4.5 /r. (Plate 12, fig. 3). 
The cells of this variety are considerable longer than the typi¬ 
cal A. Hantzschi. 
III. Bear (rr).
