such as Pirata Sund., Trochosa 0. Koch, Arctosa C. Koch, 

 Tarentula C. Koch, Potamia C. Koch, &c., have been abandoned 

 by later writers. 



M. Simon (Hist. Kat. des Ai'aign. vol. ii. pp. 317 et seqq., 1898) 

 separates the main grouj) into those species following Lycosa 

 Latreille, but further divides it into a number of sub-types and 

 those following Pardosa 0. 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 chai-acter the tarsal joint of the fourth pair of legs 

 longer than the patella cimi tibia of the same. 



Some years ago, following these lines, I constituted, a new genus, 

 which I called Venator (Proc. Royal Soc. Yictoria, 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 j^atella iv. 



However, the more specimens I examine the more the onl}"^ 

 tangible characteristics show themselves to be intei'changed, 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 

 Exj)ed. part ii, p. 349, 1896) I described L. coivlei 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. 



Synojysis of Species. 



In all. Three lai'ge equal sized-teetli on inner margin of falx-slieatli. Front row^ 

 of eyes shorter than middle row. 



a. Eyes of front row of eqnal width.

than the diameter of e3'es of front row i. tasmanica, sp. nov. 



b. Diameter of median ejes of front row larger than laterals. 

 «!. Clypeus wider than the diameter of the front median 



eyes. 

 «'. No distinguishable pattern on under side of abdomen. 

 Abdomen underneath pale yellow-brown. Tibial 

 joint of palp longer than patellar Cephalo- 

 thorax equal in length to patella cum tibia iv. . L. arenaris, sp. nov. 

 J2. A shield-shaped o]- triangular field on under side of 

 abdomen. 

 a'^. A fawn-coloured shield on a dark brown ground. 



Cephalothorax shorter than patella cum tibia iv. L. molyneuxi, sp. nov. 

 6-*. A.black shield on j'ellow-brown ground.
