Test nearly resembling in form that of the preceding 

 species, but incrusted, sometimes very thickly, with 

 sand-grains ; opaque ; compressed ; the neck thicker 

 than in L. spiralis, more angular, usually with a broader 

 base, and without the graceful curvature characteristic 

 of that species. Nucleus and pseudopodia normal. 



Dimensions: Average length 100 /x; breadth 80 /n. 



In boggy places at Dunham and Chelford, Cheshire ; 

 amongst Sphagnum, Sychnant Pass, Carnarvonshire. 

 Pond at Chipperfield, Herts (A. Earland). Above 

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

 Wicklow, Ireland (./. Hopldnson}. Loch Ness, Scotland 

 (D. J. Scour f eld). 



This species is less frequent with us than L. spiralis; 

 it is found mostly in bogs, occasionally also in ponds, 

 living in the ooze along with the larger forms of 

 Difflugia. The test is generally more compressed than 

 that of L. spiralis., and the tube or neck thicker and 

 shorter. Examples found by Penard on the margins 

 of some of the Swiss lakes had a variable number of 

 siliceous rods mingled with the quartz-grains which 

 composed the test, but more frequently irregular or 

 rounded plates or membranous scales.
