seminal receptacle is a flask-shaped organ lying in a plane 
slightly anterior to the ovary. Between it and the ootype rising 
dorsad, is a small Laurer’s canal (Plate 1, fig. 6). A short 
oviduct can be traced into the ootype. Around the odtype are 
numerous shell glands. The vitellaria consist of from four to 
six large follicles on each side of the body, confined to the pos- 
terior limit. The uterine mass occupies a major portion of the 
body posterior to the acetabulum. A single coil on the right 
side of the acetabulum runs toward the genital pore, which is 
situated just below the forking of the intestine. The eggs aver- 
age 21 fjL by 11 n in diameter. 
DISCUSSION 
A close study of Phagicola pithecophagicola shows it to belong 
to a group possessing in part the characters of the Brachycoe- 
liinse, in part those of the Microphallinge, in part those that are 
unique. It differs from the Brachycoeliinge mainly in the posi- 
tion of the vitellaria, ovary, and testes. It differs from the 
Microphallinse mainly in the possession of an uninterrupted cir- 
clet of blunt spines inserted on the inner margin of the oral 
sucker. In view of the differences of these fundamental points, 
critical in the classification of trematodes, it seems wise to rec- 
ognize this as the representative of a new genus, Phagicola, and 
create for it a new subfamily, Phagicolinse. 
Designation of subfamily Phagicolinse. — Minute distomes with 
spinose body and an uninterrupted circlet of spines on the inner 
margin of the oral sucker. Caeca short, not surpassing acetab- 
ulum. Excretory bladder intermediate in type between a V- 
and a Y-form. Vitellaria postacetabular, consisting of a few 
large follicles. Testes unlobed, slightly oblique, far postace- 
tabular. Ovary, seminal receptacle and seminal vesicle postace- 
tabular. Cirrus sac and prostate glands lacking, cirrus tube 
nonmuscular. Genital pore antacetabular. 
Type and sole genus, Phagicola. 
Type species, Phagicola pithecophagicola.
