Amwbx, showing that Sphagnum is not essential to its 
existence. Moreover Dr. Penard was more fortunate 
than Dr. Lankester in being able, from the abundant 
examples which he found, to trace its life-history. 
Dr. Lankester, in his article in the ‘Quarterly 
Journal of Microscopical Science,’ was able to give a 
full description of C. montana im its active phase. Its 
most striking peculiarity was found in the threads, 
and the “ oat-shaped corpuscles’ by which they were

to Archer, one of the leading characteristics of his 
U. labyrinthuloides, and comparable to the nucleated 
spindle-shaped bodies which travel upon the threads 
of the Labyrinthula of Cienkowski. The threads are 
of extreme tenuity. “I never,’ he says, “saw any 
thread either fuse’with a neighbouring thread or divide 
into two. It appears to me (but the observation is 
difficult) that when two threads come together they 
may be very closely apposed, but nevertheless retain
