Figure 1 in A further study on littoral ciliates (Protozoa, Ciliophora) near King George Island, Antarctica, with description of a new genus and seven new species

Figure 1. Urotricha antarctica nov. spec. (A–C), Chlamydonella apoprostomata nov. spec. (D– F) and Hartmannula angustipilosa (G–J) after protargol impregnation. (A) General view of morphology, to show the macronucleus (Ma) and contractile vacuole (CV). (B) Apical view, to show the cytostome area; note the circumoral kinety (CK). Arrow marks the dorsal brush. (C) Caudal view, arrowheads mark the kinety ring, arrow indicates the contractile vacuole pores, while double-arrowheads mark the caudal cilia. (D) Ventral view, to show the general ciliature, arrow marks the leftmost end of perioral kineties; arrows mark the circle of argentophilic granules, while the double-arrowheads indicate the micronucleus. (E) Buccal apparatus, to show the fragmented perioral kineties. (F) To show two specimens full of ingested diatoms. (G) Ventral view, to show the general ciliature. (H) Details in oral area, arrows mark the perioral kineties. (I, J) Anterior portion, arrow in I marks the macronucleus. AK, apical kinety; CK, circumoral kinety; Cs, cytostome; CV, contractile vacuole; EF, equatorial fragment; Ma, macronucleus; PeK, perioral kineties; Po, podite; PrK, preoral kineties; TF, terminal fragment. Scale bars: 50 Mm (A); 40 Mm (D); 60 Mm (E, F).
