its motions and when killed i4 days after the injection, exhi- 
bited no signs of bowel infection or of the flagellate in the large 
bowel, the caecum, on lovv down, in the middle, or upper end 
of the small intestine. 
We hâve fully described Enteromonas hominis in our paper 
sent to the Society of Tropical Medicine andHygiene in London 
and therefore we merely State that we confirin the findings of da 
Fonseca with regard to the absence of an axostyle, of a perman¬ 
ent cytostome, and of an undulating membrane and we agréé 
that the nucléus is a protokaryon and is joined to the blepharo- 
plasts by means of a rhizoplast. 
We however find thatusually two blepharoplasts are présent 
and that the three flagella are distinctly anterior in direction 
and we consider that noue of them are truly trailing. 
We hâve reported stages of binary division and early cyst 
formation. 
We consider that the genus belongs to the family Tetramitidae 
as defîned in our paper on Chilomastix and to our subfamily 
Tetramitidinae and that it should be defined as follows : 
Tretramitidinae without cytostome and with three unequal 
anterior flagella. 
We think that it is al lied to the genus Dallengeria Saville 
Kent 1880 and that there is only one known species viz., 
E. hominis , the characters of which are illustrated by the three 
photomicrographs atlached to t h is paper. 
Diagnosis. — The presence of E. hominis in man seems to te 
associated with chrouic diarrhoea appearing as intermittent 
subacute attacks and with vague abdominal pains. The attacks 
only last a few days unless aggravated bx exercise or other con¬ 
ditions. 
The diagnosis can only be made by microscopical examina¬ 
tion, preferably, of the fluid portions of the motion. 
Directly after mounting on a slide and under a cover slip 
the parasites seem to remain molionless for a few minutes and 
then to move about very actively, and, as far as our expérience 
goes, a length of time must elapse before the movements are 
slow enough to enable the details of the organism to be reco- 
gnised. 
Unless présent in very large numbers it is apt to be overlooked.
