Description of Euglypha compressa
provided by BioPedia
The test is colourless, obovoid, compressed 2:1, composed of about 300 platelets (often with notched narrow side). Several 16-19 micron-long spines project singly from junctions of shell platelets close to lateral margins. Aperture elliptical, about 15 apertural platelets. Platelets thickened at denticulate margins, carrying 1 large median tooth. Presumably always 3 pairs of lateral teeth, of which only 2 are easy to see. The third is bent inward at right-angles to apertural opening, very small and thus difficult to recognize. Shell measures 65-115 microns long.
