74: Miscellaneous. 
The clear granules are minute, yellowish, and resemble fine oil glo- 
bules. They are turned deep brown by the action of iodine. 
The clear globules appear to consist of a delicate vesicular membrane 
probably derived from the primordial utricle, filled with a colourless 
fluid. 
No circulatory or other movement, as in Achyla prolifera, exists in 
the cell-contents. The end-cells of the full-grown individuals are 
usually two in number, and much shorter than the parent cell. 
Occasionally I -have found three end-cells, more frequently but one. 
These cells are formed from the parent cells by a contraction first 
taking place in the contents with the primordial utricle, a partition 
from the permanent cell-wall forming afterwards. 
The end-cells are probably spore-cases ; their contents are usually 
a dense mass of fine granules, similar to those of the parent cell, with 
a few intermingled globules. I never saw any movement, molecular 
or other, in the contained matter, except during decomposition. 
A question may arise as to the true situation of this plant among 
the Cryptogamia. I have placed it in the order Confervacee, from 
the diagnosis given by Endlicher in his ‘Genera Plantarum’ : “ Fila 
capillaria, membranacea v. filamentosa, intus v. extus articulata, sim- 
plicia v. ramosa, libera (i. e. haud in frondem coalita), interdum tamen 
reticulatim contexta, viridia v. rarius fusca aut purpurea, in formis 
infimis hyalina,” &c. 
Cladophytum, a new genus of Entophyta allied to the Mycoder- 
mata. Filaments minute, attached by means of a roundish nucleus, 
simple, or compounded near the base of attachment, with mimute 
lateral ramuli, inarticulate, and with no evidence of interior structure. 
Cladophytum comatum. Filaments delicate, regular, colourless, 
simple, more frequently branched near the base at very acute angles, 
growing in more or less dense bunches from a yellowish rounded or 
oval, attached, nuclear body varying in size from 1-7500th to 1-600th 
of an inch. Lateral ramuli very minute, measuring in length from 
1-15,000th to 1-3000th of an inch, and passing off at acute angles. 
No indication of articulation or interior structure. 
Length from 1-666th to 1-120th of an inch. 
Hab. Growing more or less profusely from the mucous membrane 
of the small intestine of Judus marginatus, occasionally from the same 
surface at the commencement of the large intestine, from any part of 
the exterior surface of entozoa infesting those cavities, and also from 
any part of the surface of Enterobrus elegans. 
Arthromitus, a second new genus of Entophyta allied to the My- 
codermata. Filaments always simple, cylindric, articulated, without 
ramuli, attached by means of a nuclear body, and with no evidence 
of interior structure. 
Arthromitus cristatus. Filaments delicate, straight or inflected, 
growing in tufts usually of moderate density, from minute, attached, 
yellowish, rounded or oval nuclear bodies. Articuli short, cylindric, 
uniform, measuring 1-9090th in. in length by 1-15,000th in breadth, 
with no traces of interior structure. 
Length 1-375th to 1-46th of an inch ; breadth 1-15,000th in.
