sure or such accident, the chlorophyll-granules do not extend 
beyond the boundary of the inner halls. 
I regret to say I have not found any other indication of a 
reproductive process, nor have I ever seen any trace of incepted 
food, though I have taken specimens at all seasons of the 
year. 
This must he accounted a rare form ; the distinct situations 
in Co. Wicklow, in which I have found it, are, perhaps, not as 
many as six, and the individual pools not quite twice that 
number, yet in some of these I almost think I should hardly 
fail to get examples, with perseverance, at any season. But 
although thus seemingly restricted to spots, and never 
abundant, I fancy this fine form may he more widely dis- 
tributed than we imagine, for only the other day I saw at 
least two examples from near Glengariff, hut they were poor 
ones. A large example, with a little experience, can be seen 
by the unassisted eye, like a greyish-green dot, almost as large 
as some specimens of Actmosphcerium Eichhornii. 
I shall again advert to this organism and its position in a 
future part of this communication.

The next type, which presents itself under two forms, is 
destitute of the hard parts characterising the two preceding, 
and thus recedes further in that regard from the true Radiolaria 
of Haeckel ; but, though wanting in anything which might be 
called skeleton, there is a part of the organization presented 
which calls to mind the ‘ yellow cells’ pervading the majority 
of that great group, so rich in multitudinous forms. But 
whilst there is seemingly a community of characters in the 
tw T o rhizopods now to be drawn attention to, I am not, indeed, 
myself yet quite satisfied that they ought truly to be regarded 
as congeneric, owing to the seemingly diverse character of their 
pseudopodia, but still, for the present at least, it is desirable 
to leave them together. As in the previous instance, I 
defer to the latter part of this communication the special 
generic and specific descriptions of the forms drawn attention 
to, giving for the present merely a few cursory remarks upon 
them. 
1 shall first advert to the form which I first met with, 
though, as experience has shown, it is greatly the more rare. 
The rhizopod which I have named Cystophrys Haeckeliana 
(PI. XVII, fig. 1), is of an irregular, though normally of a 
roundish figure, possessing, immersed in the body-mass, a
