to belong to the genus Chara. The names given to the two 
species discovered by Forbes were Purbeckersis and Valdersis. 
I cannot, of course, say that any two of those I have met with 
are identical with Forbes’, seeing that his types cannot be 
found. I also think that it would be unwise to give names to 
these I am about to describe, as they may be fructifications of 
one and the same plant. At any rate I shall leave that to some 
person more capable than myself, and be content with simply 
recording the find and brief description of the specimens. 
Fic. 1. This is the most common form of the genus which 
occurs. It consists of an axial cell and twelve cortical ones. 
The central cell is the largest, and the cortical ones consist of 
six superior and six secondary ones, with well preserved walls. 
Fic. 2 This fossil shows a large or central cell, and 
twelve cortical ones of practically equal size. This figure may 
represent a section of a cerpogonium. 
Fic. 3. This is much the larger specimen of the three, 
and the general arrangement of the cells is different from what 
we find in the specimens previously referred to. The axial cell 
is small and is surrounded by six large sized cortical cells, and 
at the points where these diverge from one another, there is a 
very small secondary cell. 
The specimens were obtained from a crystalline light 
coloured limestone, largely made up of calcified vegetable 
remains, Figs. 4and 5. The limestone also contained remains 
of Planorbis and occasional valves of Ostracoda. 
On treating the rock with hydrochloric acid the usual 
evolution of carbonic acid takes place, and a residue is left 
consisting of crypto-crystalline silica and some grains of detrital 
quartz. The crypto-crystalline silica consists of fragments of 
casts of the organisms in the limestone, and also portions of 
Characee, the organic structure of which has been replaced by 
the silica. 
With regard to the mineral conditions in which the 
Characee are preserved, I may say that in Figs. 1 and 3 the 
cells are in part filled with crystalline calcite, and in part by a 
dark substance containing some carbonaceous matter.
