Family DICTYNIDAE.

Hah. — Wantapella Swamp, South Australia. Ranges 

 from Northern Queensland to Western Australia. 



Xofe. — A. rubustus is evidently a variable species, which 

 one would naturally expect from its being so common and so 

 widely distributed. During the last twenty-five years I have 

 examined very many specimens, but cannot recall one which 

 did not differ in abdominal ornamentation from Koch's figure. 

 Captain White's specimen shows (when in alcohol) distinct 

 chevrons. 



Family PRODIDOMIDAE. 



One of the most interesting specimens collected by Captain 

 White is a species which I take to be representative of the 

 above family. This family is a very small one, and its range, 

 according to Simon, ^i) is as follows: —
