Inrropucrory.—During the autumn of 1885 I chanced, while 
examining some Alge from a pond at Lee, to come upon a ty pe then 
believed to be undescribed. This organism was bottle-shaped or 
pyriform, the narrow end attached almost exclusively to threads of 
Cladophora fracta, Kuetz., but occasionally to those of Mesocarpus 
Pleurocarpus, De Bary, as well. In its earliest stage it consisted of 
a colourless sae containing a single gonidium, from the distal end 
of which proceeded two cilia having the remarkable property of 
piercing the parent wall, and extending therefrom some distance 
into the surrounding water. This gonidium divided, the succes- 
sively formed daughter cells following suit, while the parent wall 
grew coineidently, and eventually appeared as a large sae (zoospor- 
angium) with upwards of a hundred biciliated gonidia ranged 
upon its wall. Being aequainted with the rare type called by 
Naegeli Apiocystis Brauniana, which I had been fortunate in 
finding several years previously, the resemblance between that 
and the eiliated organism was at once seen; but the protruding 
cilia preveuted recognition of identity, as they seemed to point 
to a volvocineous aflinity by arguing the intercalation of a coeno- 
bial phase or phases. At the time above mentioned but scant 
opportunity offered for studying the life-history of the supposed 
novelty. However, iu the spring of this year I again had the
