such as Pirata Sund., Trochosa C, Koch, Arctosa C. Koch, 
Tarentula C. Koch, Potamia C. Koch, &c., have been abandoned 
by later writers. 
M. Simon (Hist, Nat. des Araign. vol. 1. pp. 317 e¢ segq., 1898) 
separates the main group into those species following Lycosw 
Latreille, but further divides it into a number of sub-types and 
those following Pardosa C. Koch. The former comprises species: 
which have the front aspect of the cephalothorax moderately 
sloping at the sides and a lip longer than broad; the latter those 
with the front aspect squarer with more perpendicular sides, the - 
lip broader than, or at least as broad as, long, and having as a 
subsidiary character the tarsal joint of the fourth pair of legs 
longer than the patella cwm tibia of the same. 
Some years ago, following these lines, I constituted a new genus, 
which I called Venator (Proc. Royal Soc. Victoria, vol. xiii. pt. 1, 
1900), for some species with a more extremely widened type of 
frontal aspect, but with the lip clearly broader than long and the 
tarsal joint of iv. not so long as tibia cum patella iv. 
However, the more specimens I examine the more the only 
tangible characteristics show themselves to be interchanged, and 
I look on these two genera as no more distinctly definable than 
M. Simon’s above mentioned other varieties of Lycosa (loc. cit. 
pp. 346-349). 
M. Simon further makes a division between those species with 
two teeth on the inner margin of the falx-sheath and those with 
three. 
The bulk of the Australian species have three, but (in Horn 
Exped. part ii. p. 349, 1896) I described Z. cowlei which had five 
large equal-sized teeth on same, and no other specially marked 
characteristic distinguishing it from the rest of the genus. 
Out of about 60 specimens in the present collection there are 
12 species of Lycosa, of which no fewer than 9 are new, and one 
new Dolomedes. These I have described below.
