the guondam Stereonema filaments and their accompanying Uvella- 
like terminal clusters together form Anthophysa Miilleri, that is, 
both these portions of this curious growth are part and parcel of 
the same organism, though it is not easy to perceive, regarding 
the Uvella-like group as germs, how these would again develop a 
new “Stereonema” thread, giving the stipes that name as a 
convenient one, though, of course, as Cohn most justly states, 
“Stereonema,” as either an algal or fungal genus, quite falls to 
the ground ; but, on the other hand, it might, perhaps, be too hasty 
an assumption that all Uvelle were but detached groups or clusters 
of Anthophysa. 
In connection with the foregoing, and as in a measure supple- 
mentary thereto, Mr. Archer took occasion to exhibit a production 
seemingly not uncommon in certain localities, and which he has 
several times brought down to the meetings, but had never 
presented, as on those occasions so many other objects had 
pressed themselves on attention. Of this production he had not 
been able to find any record, though doubtless such may exist ; 
he thought the present a good opportunity to show it to the Club 
on account of a possible affinity—at least, a certain amount of 
resemblance—to Anthophysa. This formed a much-compressed, 
plane, broad, more or less and indefinitely branched production, 
the branches plane, broad, more or less curved, divergent, gradually 
widening from below upwards; the ends abruptly rounded off; 
their surface furnished with interrupted coarse ridges, giving the 
whole the appearance of being formed of elongate cells ; the whole’ 
structure free ; colour yellowish, reddish, or brown. This produc- 
tion Mr. Archer had met with several times, but without being 
able to make anything more of it, until on one occasion, in company 
with Dr. Barker, who,indeed, drew attention to it,aview of a further 
characteristic was obtained. At the broad and tolerably sharply 
rounded-off extremities of the compressed branches was seen, in 
several instances, a subconical projection of colourless granular 
substance, from which was distinctly seen to emanate usually two 
long flagelliform cilia, which waved about in the water with much 
vigour. That this remarkable addition to the usual organization 
of this production was really part and parcel of it, and not an 
accidentally located foreign organism, was evidenced by the 
regularity with which it was seen in just the same way and in 
just the same situation, as well as by a kind of movement, 
comparable to a kind of circulation, of the contained granules of 
the terminal conical protuberance mentioned as bearing the cilia, 
somewhat downwards below the broad and expanded extremities 
of the branch bearing the same, as if the terminal body were not, 
indeed, seated on the extreme margin, but may have originated 
within it. But of this terminal body no definite structure could 
be made out; its outline externally was not very sharp; and in 
this state the observation rests. Perhaps further experience may 
throw a light upon the true nature of this curious organism. 
Perhaps ad interim a certain amount of analogy with Anthophysa
