Schwartz described the nodules as conspi-
cuously-raised bodies, varying from about 3 to 5
mm. in diameter, the summit of each nodule being
more or less depressed and containing a small
opening. Each nodule contained a single worm
which was somewhat deeply embedded in the
mucosa. On this evidence, he stated that the
worm should be regarded as pathogenic and pos-
sibly of economic importance.
The intestines of the calf was found studded with
nodules resembling those described by Schwartz,
their number being about 20 per foot of the in-
testines. The nodules presented a greenish ap-
pearance when fresh.
The description of the parasite is based on indivi-
duals obtained free in the lumen of the intestines.
Travassos [1937] transferred the species C.
nodulosa to his newly created genus Paracooperia.
The following points have been studied from 10
individuals collected.
The head, varying in diameter from 0.06 to
0.065 mm. bears the papillae described by
Schwartz. The oesophagus varies in length from
0.3 to 0.45 mm. and has a diameter of 0.3 to
0.45 mm. at its greatest breadth.
The male is about 9 mm. long and has a dia-
meter of about 0.14 mm. at the anterior ends of
the spicules. The appearance of the bursal rays
is in agreement with Schwartz' description, save
that the dorsal ray does not always present a
bifid appearance at its branches. In one individual
the right branch of the dorsal ray, besides giving
off the lateral branch, bears a ray-like structure
in the angle formed by the origin of the lateral
branch. This structure is absent in the corres-
ponding left branch, while the main branch has
a bifid appearance. The spicules are from 0.25
mm. to 0.28 mm. long, differing in this respect
from 0.304—0.32 mm. described by Schwartz,
and bear about ten cusps each on their median
process. The process bearing the cusps arises
about 0.04 mm. from the anterior end of the
spicule.
Females measure from 10 to 13 mm. in length
and have a width of about 0.2 mm. in the region
of the vulva. The vulva is situated about 2.5 mm.
from the tip of the tail and is covered by a promi-
nent cuticular linguiform flap. The combined
length of the ovijectors, including the sphincters,
is 0.8 mm. The tail, bearing alae, has a length
of about 0.15 mm. The eggs are 0.07 to 0.075
mm. long and 0.049 to 0.054 mm. broad.

Only fragments of this worm were collected
and identification was not possible. The eggs
measure 0.048 to 0.05 mm. long and 0.0165 to
0.017 mm. broad.

Oesophagostomum indicum [Maplestone, 1931]
The species was originally described from the
large intestines of a spotted deer and a red deer
in the Zoological Gardens, Calcutta. The two
male oesophagostomes in the writer's material
have a striking resemblance to the species under
record, the only difference being the location of the
cervical papillae. The papillae in the male
are situated half way between the cephalic groove
and the end of the oesophagus and not behind the
oesophagus as described by Maplestone [1931].
The males measure about 13 mm. in length and
have a breadth of about 0.3 mm. at the anterior
end of the spicules. There is a cephalic swelling,
with the groove situated about 0.2 mm. from
the anterior end. Each of the leaf crowns con-
tains ten broad elements. The spicules measure
about 1.55 mm. long, and the accessory piece is
about 0.065 mm.
