In a note published in “Brazil Me- 
dico” (Vol. XXXI-N. 29-p. 243 1917,) 
we showed that Allodapa should be consi- 
dered as a synonym of Subulura, the species 
included by SEURAT being considered as 
belonging to this genus. The worm called 
Allodapa numidica, described by this author 
cannot however be considered as a Subulu- 
ra, as it differs from this group by the fol- 
lowing characteristics: the structure of the 
sucker at the caudal extremity of the male, 
structure similar to that described by HALL 
as being also found in Heterakis oxynema 
cucullatum, found in the caecum of Eutamias 
amaenus operarius. The presence of two 
large cephalic expansions, and of a mouth 
bounded by three distinctly individualised 
lips in HALL’S species, forms a great contrast 
to the absence of lateral, and a buccal cavity 
with two indistinct lips in Allodapa numidi- 
ca of SEURAT, and prevents the compri- 
sing of the worms in the same group. The 
form and aspect of the long eggs (90—100 
micra by 35 micra) of Heteroxynema cucul- 
latum, and the round eggs (63 by 58 micra) 
of the species zumidica strengthen our opi- 
nion. 
Diagnosis of the genus. 
Subuluriuae: Mouth limited laterally by 
two indistinct lips, each provided with three 
papillae. Buccal capsule with thick chitinous 
walls, divided into two parts: one higher, one 
lower containing three slightly prominent 
teeth at the entrance to oesophagus. Oeso- 
phagus followed by bulb. No lateral expan- 
sions. 
Male: Spicules two, unequal, the right- 
hand one larger, very much chitinised: the 
left-hand one hardly visible on account of 
the slight chitinised layr. Gubernaculum nar- 
row strongly chitinised. Sucker represented 
by an elliptical area transversally striated, 
surrounded bya rim, covered with small tra- 
becules of cuticle. Genital papillae: 10 pairs. 
Female: Vulva prominent, taking up the 
middle third of body. Ovijector with thick 
muscular walls, turned towards anterior xe- 
tremity. Uterus double, divergent. Eggs round 
thin-shelled, hatched out. 
Habitat: intestine of Mammals (Carni- 
vora). 
Type-species and only known one: Nu- 
midica numidica (Seurat 1915) Barreto 1917. 
Geographical distribution: Africa (Alge- 
ria Blida).

Dimensions: 
S Length: 13,5 mm.; width: 0,370 mm. 
@ Length: 25 mm.: width: 0,375 mm. 
Body thin, rectilinear, posterior extre- 
mity curved. In the male cuticle, thick delicately 
transversally striated striations 0,004 mm. 
from one another. No cephalic lateral expan- 
sions. Lateral expansions very distinct, their 
colour being intense. Excretory pore opening 
on the middle ventral line, a little beyond the 
nerve collar. Mouth limited laterally by two 
indistinct lips, each with three papillae. Buccal 
cavity with strongly chitinised walls, divided 
into two parts: one higher, and one lower 
containing three not very prominent teeth at 
the entrance of oesophagus. Oesophagus 
short, slightly dilated like a club in the poste- 
rior region, communicating by very short a 
constriction with the bulb that contains chi- 
tinous plates. Nerve collar at the anterior 
fifth of oesophagus. 
Male: Oesophagus (including bulb) equal 
to 1/9 of body. Tail curved at extremity, so- 
metimes coiled, ending inthin point. Cloaca 
bounded by two lips, the posterior one vo- 
luminous and very prominent, opens at 0,275 
mm. from caudal extremity. Caudal expan- 
sions short and narrow, limited at sub-ter- 
minal region. Sucker represented by an el- 
liptical area, transversally striated and sur- 
rounded by a rim of small trabecules of cu-
