nected with bulb, ofa uniform diameter untli 
near the anus, where it ends ina rather short 
thin walled rectum with spacious lumen. 
Male: Buccal cavity: length: 0,050; width: 
0,033 mm. Excretory pore at 0,420 mm. 
from cephalic extremity. Oesophagus: 1,185 
long. longitudinal diameter of bulb 0,254 
mm.; transversal diameter 0,203 mm. Poste- 
rior extremity funnel-shaped, ending in short 
rectilinear appendix. Sucker ellipsoid, without 
chitinous rim, 0,135 mm. long 0,296 mm. dis- 
tant from genital pore. Caudal expansions 
very atrophied. Papillae: 11 pairs arranged 
thus: three pre-anal, ventral, voluminous, one 
at the side of the sucker, at the level of the 
of the juncton of the superior 1/3 with the 
lower 2/3 of the rimof that organ, one near 
the lower limit of sucker, one just above the 
anus; two ad-anal, large and equal: one la- 
teral, the other ventral; six post-anal: five 
ventral and one lateral; of the ventral, two 
are voluminous and near the anus: two are 
lesser and near the posterior extremity: one 
is very small and between the two preceding 
groups: the large lateral one is situated on 
the level of this last one. Spicules equal, 
curved, with distal sharpened extremity at 
infundibiliform proximal end; length: 1,100 
mm.; width 0,025 mm. Gubernaculum recti- 
linear and small (0,127 mm.) Anus 0,211 mm. 
from tail. 
Female: Buccal cavity: length: 0,067 mm.; 
width: 0,042 mm. Excretory pore 0,508 mm. 
from anterior extremity. Oesophagus: length 
1,285 mm. Transversal diameter of bulb : 0,205 
mm.; antero-posterior one: 0,231 mm. Tail 
straight or slightly ventrally curved, aculei- 
form, ending in small appendix. Vulva small, 
not salient, cleft, in front of the middle 
part of body. Ovijector relatively short, turn- 
ing towards cephalic extremity measuring 
0,779 mm.; vestibule small (0,313) mm. slight- 
tly muscular internal chitinous layers ; sphincter 
long, in comparison with the other species 
of, Subulura, 0,254 mm. with slightly chiti- 
nous lumen conlaining generally from 3 to 
6 eggs; horn the same length as sphincter, 
with muscular layer only slightly developed 
making a violent curve just before it joins 
the uterus. Uterus dichotomized after a length 
of 1,1799 mm., branches diverging, hooklets 
stretching from bulb of oesophagus till be- 
yond anus. Ovaries parallel in front of vulva; 
eggs elliptic with very thin shell; when emitted 
they contain embryos: length; 0,051 mm. 
width: 0,045 mm. Anus 1,146 mm. from pos- 
terior extremy.
