Test ellipsoidal, dark brown in colour, flattened or 

 concave on the ventral or bnccal face, composed of a 

 thin covering of small silicious grains and plates 

 cemented upon a brown chitinous pellicle ; aperture 

 long, arcuate, narrow, with the inner lip prolonged 

 and incurved, the outer lip usually furnished with a 

 row of pores ; plasma clear, limpid, containing 

 numerous minute granules, pale-coloured grains, and 

 food-particles of a vegetable nature ; nucleus single, 

 spherical, granular, containing a large central nucleole; 

 contractile vesicle probably absent, being replaced by 

 one or more vacuoles ; pseudopodia numerous, digitate, 

 simple or lobed, sometimes spatulate. 



Greater diameter 120-250 /A, but in the British Isles 

 usually 140-180 /x ; length of aperture equal to about 

 half the greater diameter of the test ; pores on outer 

 lip 2-3 /u, in diameter. 



Habitat. Mosses and sphagnum.

 Oxfordshire; Devonshire; Cornwall. 

 WALES. North Wales. 

 SCOTLAND. Dumfries; ? loc. (Murray).
