tified in differing from LANE, as we can 
show that 11 pairs of genital papillae are not 
always present in the species of the new 
sub-family proposed by this author. 
Even in the genus Subulura such un- 
swerving unity has not been confirmed, the 
variations in number and position of the 
caudal papillae serving to individualise the 
species of this genus. 
In an interesting monograph on the 
worms of rodents, and while speaking of 
Subulurinae HALL asserts that he prefers 
the determination of TRAVASSOS to that of 
LANE, especially on account of its type 
being an older and more known genus, 
Agreeing with HALL, we confirm his de- 
cision, and are of opinion that TRAVASSOS’ 
name must be considered as final on account 
of its priority, as his 3rd. “contribution to the 
knowledge of the Helminthological Fauna 
of Brasil” dates from February 1914 while LA- 
NE’s publication only appeared in October 
of the same year. 
Diagnosis: Acaroidea, Heterakidae Poly- 
miariae, Mouth elliptic or polygonal with 
two or three indistinct lips. Oesophagus al- 
ways followed by a bulb. Males with spin- 
dle-shaped or oval sucker without chitinous 
ring; spicules rarely absent (Heteroxynema); 
generally one ‘or two of them, equal or une- 
qual, always accompanied by an accessory 
picce. 
Type genus: Subulura MOLIN, 1860. 
Systematic Position. 
At present, the super-family Ascaroidea 
thus established, comprises : 
Ascaride Cobbold, 1864. 
Heterakinæ Railliet 
& Henri, 1912 
Heterakidæ 
Ascaroidea Railliet & Henry, Sabulurine Travas- 
Railliet & Henry, 1913 | sos, 1914 
1915 Seuratine Hall, 
| 1916 
Anisakide Railliet & Henry, 1915 
Heterocheilido Railliet & Henry, 1915. 
Cucullanido Barreto, 1916. 
Genera. 
According to TRAVASSOS, the sub-family 
Subulurinae comprises 2 genera: Subulura 
MOLIN 1899 and Oxynema LINSTOW 1899. 
LANE is of opinion that it comprises 
the following genera: Kathlania n. gen. (type 
genus) Subulura MOLIN 1860, Dacnitis DU). 
1845 and Cissophyllus RAILLIET & HENRY 
1912. 
HALL thinks that the genus Kathlania 
LANE, 1914 ought to be separated from the 
Subulurinae perhaps to range as a new sub- 
family; he considers Subulura MOLIN, 1860 
| as type genus, and includes in this sub-fa- 
mily Heteroxynema n. gen. 
We now include in the sub-family Su- 
bulurinae the five following genera: Subulu- 
ra MOLIN, 1860 Oxynema LINSTOW, 1899 
Cissophyllus RAILLIET & HENRY, 1912, 
Heteroxynema HALL 1916, and Numidica n, 
gen. Of these some are only classified tem- 
porarily, as for instance: Cissophvlius and 
Heteroxynema. 
Unfortunately, we have not yet had any 
opportunity of examining material of Chelo- 
nians nor specimens of Heteroxynema, We 
| cannot, therefore, form a definite opinion as 
to the exact position, to be occupied by these 
two genera in the classification of nemato- 
| des. 
We are however inclined to think, jud- 
ging from the descriptions and illustrations 
of the above-named authors, that the genus 
Cissophillus must be allied with the Cucul- 
lanidae RAILLIET & HENRY 1916; further, 
that the Heteroxynema of HALL, whose male 
specimens has absolutely no genital organs, 
can only be determined when fully developed 
males are described, for we are under the 
impression that this specimen was not an 
adult. 
As to the genus Kathlania LANE, 1914 
we classify it with the Subulurinae on account 
of the general aspect of the body and espe- 
cially of the conformation of the cephalic 
end of the worms of this genus. In his 
description of the species, LANE omits to 
speak of the disposition of the muscular ele-
