after their discharge as an unsegmented mass, their surface in 
living material may be seen to be very conspicuously covered 
with innumerable cilia, as is represented in the illustrations; 
and, although this has not been made out satisfactorily in liv- 
ing material, stained preparations show that the masses within 
the gelatinous envelope are similarly ciliate when first dis- 
charged. The number of zoospores developed from a single 
Although resembling some species of Pythium both in its 
slender hyphe and proliferous sporangia, this genus seems to 
be clearly distinguished from all other Phycomycetes by its 
multiciliate zoospores and their peculiar process of formation. 
In fact no other zoospores, except those of Vaucheria among 
the alge, are known to the writer to possess a similar dis- 
position of cilia. The fate of the zoospores after their escape 
was not observed, and the sexual reproduction is as yet un- 
known.

phe slender, sparingly branched, bearing terminally zoospor- 
angia becoming many times proliferous and forming an elon- 
gate series traversed by the hypha from the successive 
proliferations of which they arise. Zoospores very large, 
multiciliate over their whole surface, resulting from the divis- 
ion of the contents of the sporangia which make their exit as 
a single ciliated mass surrounded by a gelatinous membrane 
attached to the distal end of the sporangium, the successive 
envelopes, after rupturing distally, persistent around the series 
of empty sporangia.
