ynx and esophagus well marked. 
Globular acetabulum included in 
ventro-genital sac which is near 
mid line and contains no gonotyl. 
Testes lie side by side at posterior 
end of body; single small seminal 
vesicle is connected with a large 
expulsor. Ovary in front of right 
testis; globular seminal receptacle 
in front of left testis; vitellaria 
postovarial; uterine coils do not 
pass beyond testes and ventro- 
genital sac. Adults parasitic in 
mammals.

dae: Body broader than long, not 
divided into forebody and hind- 
body. Oral sucker without spines; 
mouth directed nearly or quite 
forwards. Acetabulum about equa- 
torial, opening directed forwards; 
no fold hanging over acetabulum 
or genital pore. A pseudodermis 
on spinose hind end of body. 
Prepharynx short; postpharynx 
medium long; ceca medium long, 
at first rather narrow but increas-

to body margin; excretory vesicle 
T-shaped with stem which is 
widened in its anterior portion and 
with rather long branches. Geni- 
tal pore immediately preacetabu- 
lar; no genital sucker. Testes 
broad, oviform, lobate, situated 
nearly symmetrically slightly pre- 
caudal, close to end of branches 
of excretory vesicle, diagonal; 
vasa efferentia rather long, run- 
ning almost straight mediad; vesi- 
cula seminalis small; cirrus sac 
postacetabular, dextral, slender, 
rather long. Ovary in front of 
and somewhat lateral of right 
testis, oviform, lobate; recepta- 
culum seminis postovarial, rather 
large; vitellaria composed of rather 
numerous follicles, highly devel- 
oped, extending nearly entire length 
of body margin; uterus rather 
short, narrow, v/ith only two 
slings not extending postcecal but 
reaching caudad to branches of 
excretory vesicle and lying espe- 
cially in left half of body. Eggs 
rusty brown.
