Coleps Nitzsch. 

 Two species of this genus were found, Colejjs kirtus and Coleps 

 uncinatus. 



Coleps hirtiis 0. F. Müll. 



Body small, length 38—46 ^i, breadth 18—38 //. 



The specimens were typical, having an ovate, barrel-shaped body 

 with a truncated anterior portion and a rounded posterior portion. The 

 anterior margin is denticulate, and the posterior possesses three spines. 

 The body is light-brown to white in colour. The division is transversal 

 and during division they present a curiously abnormal appearance. The 

 middle portion on which the constriction is seen, is smooth, and even 

 when the two halves become separated; one half of each of them re- 

 mains smooth and transparent while the other half is marked by the 

 reticulations. 



Habitat: Lehen (Oct., Nov.), Altwasser Breisach (Dec), Loch- 

 matten (Dec), Ziegelei Merzhausen (Dec). Zoological Garden (Nov., 

 Dec, Jan.). 



Coleps uncinatus CI. et L. 



Body small, length 60—70 jt/, breadth 28—34 ^i. 



This species is marked by the two anterior uncini placed near one 

 another on the flattened side, and by the four cusps developed posteri- 

 orly. Several of the specimens were slightly broader than those found 

 by Roux. This species is very rare. 



Habitat: Altwasser Breisach (Dec.) 



Dinophrya Biitschli. 



This genus appears to be very scarce as only one specimen was 

 found. 



Dinophrya Lieberkuhni Biitschli. 



Body small or medium sized, length 60^100 /<, breadth 30—45 a. 



The specimen found differed from that figured by Biitschli in 

 being more top-shaped, and thus a greeing more with that figured by 

 Roux. The anterior cone is replaced by a rounded portion on which 

 no cilia are found. The specimen measured 80 /< in length and 38 i^i in 

 breadth. It was found in clear limpid water. 



Habitat: Waldsee Upper (Dec). 



Amphileptus^hxh^. 

 Of this genus the two species, Amphileptus Claparedei^ and Am- 

 pkileptus carckesi, were found. 



Ampiiileptus Claparedei St. 

 Body large, length 120—159 /<, breadth 32—40 ^i.
