Tr. spiralis nov. sp. PI. I, Fig. 1. Lorica oval, dark- 

 brown, the surface longitudinally striated. The upper part

 surrounding the flagella hole are thick, of 3.1 microns in 

 breadth. The length of lorica 27 microns, the breadth 23 

 microns. 



Tr. Komarowii nov. 13 sp. ( = Tr. Wislouchu Skvortzow 

 var. Manchurica Skvortzow) var. punctata nov. var. PL II, 

 Fig. 21. This lorica has the same shape as the typical form, 

 but all the surface is covered with circular pits. Diameter 

 of the lorica is 21 to 23 microns: The breadth of the flagella 

 hole is 4 microns and of the rim 11 microns. 



Tr. Wislouchii Skvortzow var. punctulosus nov. var. 

 PI. II, Fig. 8. Lorica has also the same shape as the typical 

 form, but »is covered, except the round knobs, with dots. 

 The diameter of the lorica is 28 microns. 



Tr. Planhtonic Swir. var. omata nov. var. PL I, Fig. 19. 

 Lorica is nearly spherical, brown, thickly covered with dots 

 and rounded knobs. The tube-like neck is serrated and of 

 4.3 microns in length. Lorica is of 23 microns in length and 

 17 microns in breadth. 



Var. Gracilis nov. var. PL I, Fig. 21. Lorica nearly 

 spherical, brown, smooth. The tube-like neck is cut obli- 

 quely. Lorica is 18 microns in length and 16 microns in 

 breadth. The breadth of the neck is 2.5 microns. The 

 chromatophores are numerous. Eye spot is distinct.

 the text. Lorica is nearly sperical, brown, covered with few 

 rounded knobs, disposed in small groups of 2 or 3. Lorica 

 is of 15 to 18 microns in length and of 11 to 13 microns in 

 breadth. •
