Micrasterias Nordstedtiana Wolle. Meredith, N. H. Rare. 
Diam —170 p. These specimens differ from Wolle’s description 
and figures in that the lobes terminate in two spines instead of 
three or more. The end lobe is not so emarginate, and the projec- 
tion on the sides of the neck is larger and nearly cylindrical, end- 
ing in two spines. Fig. 14. 
M. Mahabuleshwarsensis Hobs. Meredith,N. H. Rare. In 
same material as the preceding. Rays more slender than in 
Wolle’s figure. 
* Euastrum Sibiricum Boldt (5€8). Duval county, Florida. 
Agrees well with Boldt’s description and figuyes. Diam=18y5 
length=2on; thick.=11y. It is interesting to find this Siberian 
species in Florida. Probably it will be found to have a wide dis- 
tribution, escaping notice because of its small size. Fig. 13. 
Dysphinctium viride (Corda) De Toni. (Cosmarium Cordanum 
(Breb.) Wolle.; Desmids of U.S. 1892 edition). Reported from 
Nova Scotia, and by West from Massachusetts. I find it common 
in material from Bridgeport, Conn., and Staten Island and Ithaca,. 
N.Y. Diam.26p. 
Cosmarium amoenum Breb. Frequent in collections from Flo- 
rida, and from Meredith, N. H. Typical. 
C. cyclicum Lund. Meredith, N. H. The specimens come 
close to var. sudtruncatum Hansg. 
C. elegantissimum Lund. Duval county, Fla., and Meredith, N. 
H. The specimens resemble Lundell’s figure 7, though the gran- 
ules are most commonly only faintly emarginate. Wolle’s figures 
are singularly incorrect in showing a deep linear sinus, though he 
describes it correctly in this particular. Usually about seven 
longitudinal rows of granules are visible at onee in front view- 
Diam.=22y; length=soy. Fig. 27. 
C. Minneapolitanum Hansg.(C. protuberans Lund. var. granite 
latum WWolle) (489). Ithaca, N. Y. Rather larger than Wolle’s 
specimens (diam.= 34-36 2), but similar in form. 
C. margaritatum (Lund.) Roy and Bissett (388). Meredith, N. 
H. Rare. The drawing does not show the granules well. They 
should be much larger and closer together. The position of the
