found to present a normal appearance on the stained films agreed well 
with the illustrations of the intestinal form, as figured by Brumpt (1913). 
Judging then by the aid of the published figures of the intestinal 
form it is in the writer’s opinion preferable to separate this from the 
mouth form, and not unite them under the specific names of hominis, 
as done by Doflein, or intestinalis by Jollos. 
The names hominis or intestinalis should be employed for the in¬ 
testinal form alone (the former has the priority claim) whilst the writer 
proposes the specific name huccalis for the mouth form, at any rate 
provisionally until such time as further research can prove that the 
important morphological differences presented by the two forms are 
merely due to different environmental conditions. 
The fact that the mouth form described in this note, possesses four 
anterior flagella, does not affect the question of specific difference; it 
merely shows that it should be placed in the subgenus Tetratrichomonas 
created by Parisi (1910). Tetratrichomonad and even pentatricho- 
monad forms occur in the intestines according to Wenyon (1915), 
though very rarely. 
The name therefore proposed for the flagellate in question is Tetra- 
triehomonas huccalis, n. sp.
