ments, and for this reason, we cannot say 
for sure, in what group this new genus 
should be placed. 
Should the study of the contractile layer 
reveal muscles of the meromyarian type of 
SCHNEIDER, the transfer to the family of 
Oxyuridae is justified: if it be of the poly- 
mayrian type with muscular cells, it is better, 
to put the genus apart as a sub-family as 
LANE does. 
In a former communication (BARRETO 
1916) we excluded the genus Cucullanus 
“ MULLER 1777 (Dacnitis DUJ. 1845) from 
the Subulurinae, making it an independent 
family Cucullanidae BARRETO 1916 (Dacni- 
tis LANE, 1914).

the genera of the Sub-family 
SUBULURINAE. 
I. Spicules absent. — Hetroxynema. 
11. Spicules present. 
1. One spicule.— Oxynema. 
2. Two spicules.

lus. 
B. Mouth with indistinct lips, 
without chitnous edges. 
a Sucker fusiform, elliptic 
without chitinous for-

b Sucker oval, with small 
trabeculae of chitin. —

Synopsis of previous work on the 
subject. 
The genus Subulura was established in 
1860 by MOLIN for a nematode found in 
the intestine of Szops brasilianus, and which 
he called Subulura acutissima. 
Several species, described before by the 
helminthologist RUDOLPHI, as belonging 
to the genus Ascaris LINNÉ and subse- 
quently considered as Heterakis by DUJAR- 
DIN, ought now to be included in the genus 
Subulura. 
In 1860, DIESING, although maintaining 
this genus as the species acutissima admitted 
a new genus (Allodapa) for the Oxyuris al- 
lodapa of CREPLIN, a parasite of the cae- 
cum of Cariama cristata, and closely rela- 
ted to Subulura acutissima. 
In 1864 COBBOLD adopted DIESING'S 
way of thinking. 
Later on, (1866) SCHNEIDER, without 
taking MOLIN and DIESING’s genera into 
account, identified the species acutissima and
