The mat.erial for this paper was obtained l)y nie from the 

 intestines of some African termites during my voyage in 

 British East Africa in the summer of 1914. The parasites 

 were taken in tiic locality of Taveta on the banks of river 

 Lumi from tho intestine of Hodofermes mossambicus Hag. 

 and Ix/iinotennes putorius Sjost., and one species I'mm termi- 

 tes found in Uganda. 



In this paper 1 am describing some new forms of Tetra- 

 mitldae partly belonging to the genus Trichomonas, which 

 is already known, and partly to altogether new genera. 



I. Trichomonas (Tetratrichomonas) termitis n. sp. 



This form is found in the intestine of termites (probably 

 RJiinofennes) taken near the town Entebbe in Uganda. Owing 

 to the presence of 4 free flagella (besides an undulating 

 membrane), this form must be referred to the sub-genus 

 Tftrittrichomonas established by Pari si (21). 



The chief point of interest in the species described by 

 me is its very presence in the intestine of termites. The 

 question of the origin and affinities of Trie honymphidae 

 has been fre(|uently discussed recently, and they were often 

 connected with the typical Mastigophora from the genus 

 Trichomonas. However, until the present the sjjecies of this 

 genus were found nearly without exception in different 

 vertebrates; only in 1882 (Irassi found one Trichomonas in
