Peridinium Lomnickii Woloszynska 1916 (= P. Lomnickii var. punctulatum 
Lindem 1924; Glenodinium Lomnickii (Wolosz.) Lindemann 1928) fig. 452 
The egg-shaped cells are slightly flattened dorsal-ventrally, with 
an opening at the apex. They are 25-40mu long and 22-35mu wide. The 
campanulate epivalve is distinctly larger than the hypovalve, which is 
rounded and sometimes indented at the rear. The wide circular sulcus 
is left-wise coiled. The ventral sulcus does not overlap the epivalve 
nor reach the posterior end of the hypovalve. The plates are covered 
with numerous warts and spines. The furrows are sometimes striated. 
Chromatophores are small and yellow brown; the nucleus is oval. 
Sometimes oil spots are visible within the cells. The cysts are egg-
shaped with a thick wall and undulating surface. 
This species is found mainly during winter in small planktonic 
lakes in Poland, Holland, France and Central Europe. 
Var. splendida Woloszynska 1916 (= Glenodinium Lomnickii var. splendida 
(Wolosz.) Lindemann 1928) fig. 453. 
Cells are 5-sided, strongly flattened dorsal-ventrally, 30-50um long and 
28-40um wide. The epivalve is larger than the hypovalve, while the right-
hand side of the cell is more stretched than the left. The plates are 
densely covered with spines. On both sides of the rhombic plate there are 
two serrated horns. The wide furrows are striated cross-wise. The 
chromatophores are dark brown. The cysts are irregular oval, surrounded 
by thick walls. The variety is found in the spring plankton of small lakes 
in the Lwow region of Poland and throughout Western Europe. According to 
Holl this species is an oxygen lover, being found in acidic, humic 
waters, pH4-6, containing large amounts of iron. 

Peridinium Wierzejskii Woloszynska 1916 (= Glenodinium Loiiinickii var. Wierzejskii 
(Wolosz.) Lindemann 1928) (fig. 455) 
Cells are spherical and not flattened dorsal ventrally, 20-30-35 mu wide with 
an apical opening. The orbital sulcus is coiled leftwise. The ventral sulcus 
overlaps the epivalve very insignificantly, extending slightly into the rear and 
does not completely reach the end of the hypovalve. The right antapical plate 
is smaller than the left. Plates are densely covered with minute warts. The 
furrows are often wide, sometimes with transverse striations. A round nucleus 
is positioned centrally. 
Found in the plankton of Lake Smreczynski in the Tatra Mts., Poland.
