Cothurnia maritima Ehrenberg, 1838

( Fig. 1-2 )

Diagnosis. Loricate, stalked peritrich ciliate. Lorica much longer than wide, occasionally with irregular ridges and furrows. The external stalk is relatively long; the short and broad endostyle is also present, mesostyle absent. Macronucleus straight. Marine species, attached to different substrates.

It should be mentioned that in our materials the individuals with furrows of lorica neither were observed.

Measurements (in µm): lorica height 39-48 (35-56 after Warren and Paynter 1991), width 29-42 (28-33 after Warren and Paynter 1991); external stalk length 8-19 (10-15 after Warren and Paynter 1991); endostyle length 4-11, width 6-11.
