AND THE ZOOLOGY OF CHINA 97 



(PL I, Fig. 24), Tr. cijlindrica var. punctata (PL I, Fig. 29), 

 Tr. Kelloggii var. limosa (Fig. 6 in the text), Tr. Arnoldiana 

 var. formosa (PL II, fig. 15), Tr. sp: (PL I, Fig. 28)— have 

 only large points under the form of round pits on the surface 

 of the brown lorica. 



From a study of much material on Trachelomonas from 

 Manchuria and from other places of Asia, I have come to the 

 conclusion that these organisms are very polymorphous and 

 often there are signs of one kind uniting with another. A 

 large variation was observed, especially in Tr. volvocina, var. 

 cervicula (PL II, Fig. 9), Tr. verrucosa var. ornata (PL II, 

 Fig. 2),_ Tr. Kelloggii (PL I, Figs. 7 and 8), Tr. globulars, 

 Tr. Wislouchii, Tr. oblonga, Tr. hispida, Tr. armata, 

 Tr. paludosa, Tr. Raciborskii. 



In the present notes I give the list of 48 Trachelomonas 

 among which 42 are described as new species and varieties, 

 two kinds of Trachelomonas are not defined and other three 

 forms with names are taken from my first work. At the same 

 time I have made some alterations in the classification and 

 all this new grouping comes from the study of all existing 

 species. During the summer of 1907 in the environs of 

 Harbin there were seen 13 kinds of Flagellata not observed 

 in Manchuria previously, and they are Euglena tripteris 

 (Duj.) Klebs, Phacus striata Fr., Lepocinclis fusiformis 

 (corda) Lemm., Lepocinclis sphagnophila Lemm., Lepocin- 

 clis texta (Duj.) Lemm., Trachelomonas pulchra Swir., 

 Tr. incertra Lemm., Tr. reticulata var. punctata (Lemm.) 

 ( = Tr. incerta var. punctata Lemm.), Tr. reticulata var. 

 amphora (Swir.) ( = Tr. amphora Swir.), Tr. Schaninslandii 

 Lemm., Tr. Rasiborskii Wolosz, Tr. piscatoris var. granulata 

 Skvortzow and Eutosiphon ovatum Stokes. 



The list of new Trachelomonas is : — 



Trachelomonas Manchurica nov. sp. ( = Tr. globularis 

 (Awer.) Lemm.) var. longispina Skvortzow. 



Var. Arnoldiana 11 nov. var. PL II, Fig. 24. Lorica 

 spherical, brown in colour, covered with dots and sharp- 

 pointed long spines 10-12 in number of 7-8 microns in length 

 and with 8 small rounded knobs around the nagella hole. 

 Diameter of the lorica is 18 microns. 



Tr. poltavica (Swir.) nov. 12 var. atomaria nov. var. PL II, 

 Fig. 20. Lorica spherical, round, dotted, bright-yellow in 

 colour. The upper part is contracted and passes directly 

 to the neck. The diameter of the lorica is 14 to 16 microns. 



11 Named in honour of Mr. Boris E. Arnold who has collected this 

 Trachelomonas at Harbin. 



12 The present species is apportioned by me from Tr. granulata 

 Swir. var. poltavice Swir.
