publication and knowing only the synopsis 
of it published in Bull. of Trop. Dis: Unlike 
kysts, these forms have no distinct membrane, 
but only a periplastic layer which is hardly 
more differentiated than that of theordinary 
vegetative forms. The internal structure is 
the same as that of vegetative flagellates, 
but the undulating membrane iscurled round 
the body; its rim touches the external limit 
while its basal line forms a more internal 
and very much bent band. In the centra! re- 
‘gion we find the normal nucleus and round 
it, characteristically disposed siderophilous 
granules. In these, as in the vegetative forms, 
I often observed the above mentioned hexa- 
gonal corpuscles. I believe that the kysts 
described by BRUG were only found in 
tracts of the intestine below those which 
yielded the vegetative forms, whereas the 
ones I here describe were found in large 
numbers, together with equally numerous 
vegetative forms, in the same part of the 
gut. 
I also saw vegetative forms which se- 
emed to be evolving towards cystoid ones 
(fig. 3). 
In the coecum of the domestic fowl, I 
found very minute cystoid forms but cannot 
decide wheter they belong to 7. eberthi or 
to 7. gallinarum, as these species coexisted 
in the hosts examined. 
111.—Some parasitic flagellates found in 
Brazil. 
Genus Globomonas FONSECA, 1918. 
Brazil-Medico, vol. 32, no 31 p. 
Diagnosis: Spheric protomonadina, with 
two equal anterior flagella.

I have been studying this flagellate for 
a long time, but it is only lately that I have 
come to know its morphology and the 
structure of its flagella, both of which are

indispensable for the determination of not 
definitive y fixed specimens. Among those 
stained by HEIDENHAINS method there 
were often very diminutive biflageilate forms, 
with a structure like that of any typic pro- 
tomonadina. As they where very small it was 
very difficult, to come to any oefinite con- 
clusions; the specimens did not fit into any 
of the existing genera. It was only in DOF- 
LEINS book that I found an illustration, 
which corresponds to G/. parasitica. 
Description: Body spheric, regular, without 
any trace of axostyle, cytostome or analo- 
gous structure; only plasm and nucleo-fia- 
gellar apparatus. 
Plasm divided in endo and ectoplasm; the 
former composed of an apparently narrow, 
continuous periplastic layer, hardly distin- 
guishable from the alveolar endoplasm; it 
must be rigid, since no metamorphic move- 
ments are perceived. There were a few 
stainable granulations, whose exact nature 
is difficult to tell, but they are probably 
inclusions. 
Nucleus generally excentric, nearer to 
the flagellar pole, mostly composed of a 
large central mass of chromatin, surrounded 
by a halo: the mass is sometimes compact, 
but may be composed of several contiguous 
granules; in some specimens I saw four of 
these, with a tiny clear space in the center 
(fig. 3). From the nuclear chromatin starts 
a rhizoplast which runs towards the ble- 
pharoplast which is sometimes double. From 
the latter spring the two flagella; they are 
slightly divergent, and anteriorly directed. 
Live specimens are easy to know as this 
species has a rotatory motion. 
Diameter: 3-5 wu. 
Habitat: Caecum of Cavia porcellus L. 
Genus ENTEROMONAS FONSECA, 1915. 
Diagnosis: Protomonadina with a long 
recurrent and free flagellum and two shor- 
ter anterior and equal ones; body globular, 
without axostyle, cvtostome and undulating 
membrane.
