INTRODUCTION. 
In previous papers are described species of Protozoa resident 
in the hind gut of the Indian termite Archotermopsis 
wroughtoni Desn. It is my purpose here to give an

already described by Lmms (11) under the term Tricho- 
nympha (Holomastigotoides) pristina. 
The true name for the animal is undoubtedly Pseudo- 
trichonympha pristina, but owing to an unfortunate 
mistake made by Grassi in his earlier papers a good deal of
