The neck is very long and flexible, being often 10 — 14 times as 

 long as the body. 



I have followed Schewiakoff in placing together L. miser and L. 

 ivrxesniowskii. 



Habitat: Universitätswiese (Nov., Dec), Brunnen Herdern (Dec), 

 Altwasser Breisach (Dec), Elsässer Breisach (Dec, Jan.). 



Lionotus vesimdosus Stokes. 



Body very large, length 580—595 //, breadth 30 — 32 /<. 



This species is distinguished by its thread-like form and the abun- 

 dant contractile vacuoles which are spread throughout the plasma, by 

 its trichocysts and its rapid movements. This species is very rares one 

 specimen only being found. 



Habitat: Elsässer Breisach (Dec). 



Lionotus cUapJiamis Wrzesn. 



Body very large, length 300 //, breadth 53 — 57 fi. 



The specimens were typical, being distinguished by the number and 

 the arrangement of the contractile vacuoles. 



This species is not common. 



Habitat: Universitätswiese (Dec), Altwasser Breisach (Dec), El- 

 sässer Breisach (Dec). 



Loxophyllum Duj. 



Of this genus only one species was found, Loxophyllum meleagris. 

 Loxophylluui meleagris O. F. Müll. 



Body very large, length 270—370 u, breadth 100—140 {.i. 



The specimens did not differ in any way from the typical Lax. me- 

 leagris. The hyahne layer is very marked. The trichocysts are arranged 

 in groups on the dorsal surface, but evenly distributed on the ventral. 

 In all the specimens the macronucleus was moniliform. The contractile 

 vacuole is posteroterminal in position, cylindrical in shape, with a long 

 canal shaped prolongation that runs along the dorsal side almost to the 

 anterior end. 



Habitat: Kandel (Nov.), Brunnen Herdern (Dec), Ziegelei Merz- 

 hausen (Dec). 



Trachelius Schrank. 



The species Trachelius ovum was found. 



Trachelius ovum Ehrbg. 



Body very large, length 300—600 //, breadth 150—160 ^i. 



The specimens found were typical, but none exceeded 304 /t in 

 length. The breadth varied from 150—160 j». The trunk was shorter
