HALL shares the opinion of SEURAT. 
In a note we published (vid. BARRETO 
1917) we proved that the genus Allodapa 
cannot exist in helminthology, as the typical 
species of DIESING has all the characteris- 
tics of the genus Subulura. Those on which 
SEURAT and HALL based their classifica- 
tion of the formed genus i, cannot be left 
in the helminthological system as they 
are Slight variations to be used only in dis- 
tinguishing the different species of the same 
genus. 
Diagnosis. 
Subulurinae: Mouth dorso-ventral, hexa- 
gonal orelliptic of which the are with three 
small indistinct equal lips and cephalic pa- 
pillae mostly. Buccal cavity distinct, furnished 
with three small teeth at the base; oesopha- 
gus always ending in bulb lateral. Membra- 
nes often found. Male: spicules, two equal 
or unequal, with accessory piece. Sucker spin- 
dleshaped or ellipsoid without chitinous rim. 
Caudal expansion rudimentary or wanting. 
Caudal papillae arranged in longitudinal 
rows, never morethan eleven pairs. Female:. 
Vulva only slighlly apparcnt, opening in the 
middle third of the body, duct turned either 
towards the anterior or posterior extremity. 
Uterus with diverging branches (?). Ova el- 
liptic with thin shell, with or without embryo 
when laid. 
Habitat: Ventricle and intestine (chiefly 
caecum) in birds; generally the large intesti- 
ne in Mammals; also intestine of reptiles.
