C. Subgenus FILARIA Mueller, 1787. 
For synonymj" see p. 36. 
Some species of Fllaria are described as possessing a transverse 
striation, others as without such striation. A difference of this kind, 
if constant in the species in question, would probably represent at 
least a subgeneric, possibly a generic character — that is, assuming 
the striation to be distinct, as we find it in certain other groups of 
Xematoda. The exact nature of the striation reported for some of 
the Filariidde, may well be restudied, however, for it does not seem to 
be excluded that at least in some cases a pseudostriation may perhaps 
have been erroneously interpreted as a true striation. According to 
Alessandrini, Milana martis (the generic type) is not transverse!}" 
striated. Fntil this species is restudied it can not be positively 
stated which other species of Filaria should be placed in the typical 
subgenus, and while it is possible that some of the forms which are 
found in man may belong here, this point may well be left open until 
the generic type is better understood. 
D. Subgenus uncertain. 
Until Filaria martis is restudied, in order to determine the characters 
of the typical subgenus, the exact systematic subgeneric position of 
the folloAving parasites of man (and also of nearly all the other species 
of Filaria reported for different animals) remains sub judice.
