Lepocinclis fusiformis (Carter) Lemmermann 1901, p. 89 



PL 89, Figs. 1-4 

 Cells broadly fusiform or pyriform, slightly produced posteriorly 

 to form a blunt basal point; membrane spirally striated; paramylon 

 bodies 2 to several circular plates; flageUum about as long as the 

 cell; 15-1 7/A in diameter and up to 36/a long.

Lepocinclis fusiformis var. major Fritsch & Rich 1930, p. 72 



PI. 89, Figs. 7, 15 



Cells elongate-ovoid to subfusiform, broadest below the midregion, 

 produced posteriorly into a very short obtuse tail-piece; usually 

 with a bipapillate protrusion at the anterior end; periplast sometimes 

 with extremely fine spiral striations (almost straight in our speci- 

 mens); paramylon bodies 2 very large oval rings, sometimes over- 

 lapping one another; chloroplasts numerous irregularly shaped discs; 

 cells 25-29- (39) /A in diameter, 39-58/x long. 



This variety is originally described as having, at times, many small 

 paramylon bodies, but our specimens showed only the large rings. 

 The periplast is very faintly striated, a character seen only under 

 favorable conditions. This species should be compared with L. 

 Steinii Lemm. and L. costata Playf. These species are somewhat 

 similar in shape but differ in size and details of the periplast fea- 

 tures, as well as in the form of the paramylon bodies.

Lepocinclis glabra Drezepolski 1925, p. 269 



PI. 89, Fig. 14 



Cells broadly ellipsoid or ovoid, broadly rounded posteriorly but 



with a short, blunt caudus; very slightly narrowed anteriorly, with 



a bipapillate protrusion through which the flagellum arises; flagellum 



about as long as the body; periplast smooth ( ? ) ; paramylon in the 



form of 2 very large, curved plates, one on either side and in certain 



positions appearing as 4 plates; cells 19-21;u, in diameter, 25-31jm long.

Lepocinclis glabra fa. minor Prescott 1944, p. 370 



PI. 89, Fig. 10 



Cells broadly ovoid, with a short papilla-like caudus, broadly 

 rounded anteriorly and ending in a bipapillate protrusion through 

 which the flagellum emerges; flagellum about as long as the body; 

 periplast smooth; paramylon in the form of 2 semicircular bands,
