Encysted Condition of Uvella.—Referring to the observa- 
tions made at the Club meeting, February, 1871 (‘ Quart. 
Journ. Mier. Sci.,’ Vol. XI, N. S., p. 316), as to the possible 
relationship of Synura, Synerypta, and Uvella (Ehr.), with 
the marine form MWMagosphera, forming the type of Hackel’s 
Catalacta (‘ Biologische Studien,’ p. 139), Mr. Archer now pre- 
sented examples of the common Uvella in an encysted condition, 
quite parallel to the same state of Synwra and Synerypta, and 
conjecturally also of Magosphera itself. Here the little encysted 
constituent ‘“‘monads”’ formed a group, each now quite globular, 
rather thick-walled, the contents bluish, very refractive, and each 
invested by a special outer covering (standing slightly away from 
the wall), this quite hyaline but rather coarsely granulate. No 
“ameeboid’’ phase had yet been noticed. A nearly similar 
encysted state occurs in Dinobryon sertularia (specimens were 
shown) and there is no doubt a certain “ affinity.” In the forms 
Syncrypta and Uvella (are they truly generically distinct?) the 
monads radiate from a common centre; in Synwra they terminate 
the ultimate branches of a dichotomously arborescent structure, 
starting from a common connecting piece (like two trees growing 
in opposite directions, with a common trunk, but no roots) ; thus 
as regards the dendroid stipites there is a certain amount of 
bilaterality sometimes even expressed by a greater or less indica- 
tion of a figure-of-8 shape of the outer circumference of the 
colony. But in Dinobryon sertularia the monads exnibit a 
dichotomously branched “ polypidom”’ starting from a single basal 
point; however, in the “quill-like’’ Deznobryon noticed by Mr. 
Archer before the Club, April 16th, 1868, the tubular ‘ urceoli” of 
this structure radiate with a “ fan-like’’ sub-hemispherical outline 
from a common centre. Thus though the present be but an 
isolated little note, it might have possibly some bearing on the 
question of the true nature of these organisms. 
Prothallus of Fern, with Scalariform Ducts, exhibited—Mr. 
Archer exhibited a preparation from Mr. James Abbott, com- 
municated by Professor Thiselton Dyer, of a prothallus of an 
unknown fern, showing scalariform ducts, as first drawn attention 
to by Dr. Farlow. The ducts were very readily seen, in one 
example forming an elongated bundle, and in another in the 
condition of but as yet ordinarily formed cells with the scalari- 
form deposit. No rudiments were evident in this specimen of 
the primordial asexually produced leaflet or rootlet, as described 
by Dr. Farlow, the position which such occupies, near the sinus 
of the prothallus, being quite empty.
