Amoebse, 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 in 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 

 0. labyrinthuloides, and comparable to the nucleated 

 spindle-shaped bodies which travel upon the threads 

 of the Labi/rinthula 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
