NEBELA MILITARIS. 105 



to six, usually very active. The nucleus normally 

 situated. 



Dimensions: Length 50-70 p; breadth 25-35 p.. 



In Sphagnum, frequent. Dunham, Cheshire; Sych- 

 nant Pass, Carnarvonshire. Moel Siabod and above 

 Dolgam, Capel Curig, N. Wales; and Killough, Co. 

 Wicklow, Ireland (J. Hopkinsori). Pentland Hills and 

 Ben Ledi, Scotland (W. Evans). 



This pretty little Nebela is easily recognized, and 

 except that some examples are broader in proportion 

 than others, it shows little tendency to vary. No other 

 Nebela has the same thickened lips. The test, which 

 is usually distinctly marked, is very transparent. The 

 plasma, not occupying the whole of the interior, is 

 attached to the walls and summit by extensions of 

 ectoplasm. In the encysted state the plasma is drawn 

 up towards the fundus, and appears as an elliptical 

 compressed body, the rest of the cavity being un- 

 occupied.
