BULLETIN OF THE LABORATORIES 
List of Alg^ from Granville, O. 
The following list adds a number of species to that given by Mr. 
H. L. Jones in volume II. 
1. Spirogyra dubia. 
2. Spirogyra adnata. 
3. Spirogyra fluviatihs. 
Jf. Spirogyra sp. (see below.) 
5. Zygnema a'uciatum. 
6. Zygjnena stellatu77i {genui7tu77i.) 
7. Oedog07iium f7'agile. 
8. Oedogoniurn polyTnorphimi. 
9. Chcetophora fusiformis. 
10. Co7ife7'va rhyphophila. This plant grows in troughs and 
deep pools and stands perpendicular in great green masses resembling 
pillars. The stems are very fine threads and much crowded together. 
11. Oscillaria tenuis. 
12. Oscilla7'ia. 
13. Hyalotheca mucosa. 
llf. Closteriuni acerosu7n. 
15. Miscraste7'ias truncata. 
16. Nos toe rupestre. 
17.. Wolfia colu7nhiana. (Not properly included in a list of 
algcE, but mentioned on account of its association.) 
Numbers i, 2 , and 12 of the above list were found in a pond fed 
by a spring and had their filaments commingled. In like manner, 5 , 
6 , 7 , 9 , and r 6 were closely associated. The nostoc was very sticky, 
so that the stems of the other plants, spores, and debris clung to masses 
of it. When the spores developed, the stems would grow all about 
among the Nostoc fronds. 
The Spirogyra numbered 4 , appears to be undescribed. Should 
this prove to be the case I would wish to call it 
Spirogyra herricki sp. n. 
Diameter about 3 m.; cells 2 to 4 times as long as broad ; spirals 
3 , making to a little more than 2 turns; cells not folded or re- 
plicate at the ends ; spirals rather narrow, light green ; fertile cells 
swollen; spore 42 m. by 22 m.
