Cniptochilum Maup. 

 Of this genus one species, Cryptochilum nigricans^ was found. 



Crypiochiliim nigricans 0. F. Müll. 



Body very small or small, length 16 — 50 //, breadth 4—20 //. 



The body is elongated, oval and laterally compressed. The dorsal 

 face is convex, and the ventral face is flat and slightly concave. The 

 specimens were not quite typical, both faces being slightly convex, but 

 did not differ in any other feature. 



Habitat: Zoological Garden (Jan., Febr.). 



Leucophrydium Roux. 



The single species that forms the genus, Leucophrydium putrinum 

 was found. 



Leucophrydium putrinum Roux. 



Body large, length 120—130 ^/, breadth 70-75 /(. 



The specimens did not differ from the type except in having fewer 

 secondary contractile vacuoles. The species is very rare. 



Habitat: Tank near railway Station (Nov.), Zoological Garden (Oct.). 



Olaucoma Ehrbg. 



Of this genus Olaucoma scintillans and Glaucoma pyriformis were 

 found. 



Glaucoma scintillans Ehrbg. 



Body small or of medium size, length 60 — 86 f-i^ breadth 36 — 56 (.i. 



The specimens were typical, and possessed a very large undulating 

 membrane which was always in motion. The species is very common. 



Habitat: Kandel (Nov.), Lehen (Nov., Dec), Waldsee Upper (Dec), 

 Waldsee Lower (Nov.), Universitätswiese (Nov.), Zoological Garden 

 (Oct., Dec, Jan.), Brunnen Herdern (Dec). 



Glaucoma pyriformis Ehrbg. 



Body small or of medium size, length 38 — 75 ^<, breadth 24 — 47 ^i. 



The specimens were typical. They are distinguished from the 

 former species by the general shape, and by the difference in the size of 

 the undulating membrane. Several specimens were found which agreed 

 with Gl. scintillans in general shape, but in the position and shape of 

 the undulating membrane came nearest to the present species and so 

 are included. 



Habitat: Lehen (Nov.), Lochmatten (Dec), Zoological Garden 

 (Dec, Jan.). 



Frontonia Ehrbg. 



Of this genus only one species Frontonia acuminata was found.
