GLEOTENUM, Hansg. 
G. Loitlesbergereanum, Hansg. The following is Professor 
Schmidle’s note :—“ Abundant in the collection from Jenkins’ Quarry, 
made by Mr. W. J. Byram. It is perhaps worthy of notice that 
in this habitat Cylindrocapsa geminella, Wolle, of which our alga 
should, according to Stockmayer, be a phase of development, was not 
present, at all events not in my material. In spite 
occurrence I have only observed the two-celled form, which was 
moreover distinguished by having the gelatinous envelope at each of 
the ends prolonged into three lobes in somewhat symmetrical arrange 
ment. (Plate II.) 
_ _ This alga has hitherto only been known to occur in a few places 
in Europe and in India. (Plate IIT.) 
SPIROGYRA, Link. 
S. Baileyi, W. Schmidie. This species is new to science, and we 
are indebted to Professor Schmidle for its determination and for the 
following description of it :—‘‘ The vegetative cells are 20-24 px broad, 
128-200 p long ; its cell membrane at the ends is not drawn back. 
They contain two fairly broad chlorophyll bands, with 3-4 revolutions.

one band enumerated in the section Conjugata (Vauch.), Et poe

to me to be wrong. Kirchner, in the ‘ Alge of Silesia,’ p. 128, i 
does the same with regard to the non-inflated spore-cells.” (Plate “™
