Subfamily FILARIIN^, new subfamily. 
The subfamily which contains Filaria must be named Filariinae. 
Its full characters are not established at present, but one of its chief 
characters must be the presence of a vulva in the adult female. 
Grem:is IVIlLiAR-IA ivr.iaellei% IT'87'. 
The t}^pe of this genus must be carefully restudied before a satis- 
factory generic diagnosis (see p. 34) is written. For the present we 
may divide it into three subgenera, to contain the filaria reported for 
man, but it is quite probable that these subgenera will later be given 
generic rank. Thelazia also comes into consideration as a possible 
subgenus of Filaria. For a list of the species of Filaria which have 
been taken as types of distinct genera see p. 37. 
For the purposes of this paper the remaining species of ‘‘^Filaria" 
reported for man will be arranged as follows: 
A. Subgenus Hamularia Treutler, 1793. 
B. Subgenus Loa Stiles, 1905. 
C. Subgenus Filaria Mueller, 1787. 
D. Subgenus uncertain. 
(a) Unstriated. 
(b) Striated. 
(c) Not stated. 
(d) Not satisfactorily established as occurring' in man. 
E. Collective group 2licroiilaria.^^ 
F. Species eliminated from subgenus Filaria and probably from 
genus Filaria. 
G. Collective group Agamofilaria. 
H. Genus Filocapsularia. 
I. Species probably to be eliminated both from Filaria and Filariidse. 
J. Species definitely eliminated from genus Filaria and also from 
family Filariidde.
