River, and that they esteem this crustacean as an article of 

 food. He believes that the crayfish dig holes in the banks 

 as the water dries up and remain there till the river flows 

 again. 



Pal.emon ornatus, Olivier. — One larva. "Only twice 

 did we meet with these crustaceans; one in a large pool at 

 Running Waters and one in a waterhole near Hermanns- 

 burg."— (S. A. White.)

ARANEID^E. 



By R. H. Pulleine, M.B. 



Captain S. A. White, during his travels in Central 

 Australia in 1913, collected a number of species of Araneidce 

 which have been handed to me for determination. 



The circumstances under which they were collected made 

 many specimens difficult or impossible to determine, as the col- 

 lecting apparatus and collections had to be carried on camels, 

 which caused much maceration and dismemberment of the 

 specimens. Spiders particularly stand this treatment badly. 

 The large Spdrassidce came through the ordeal best, while the 

 T erritellarice and other soft-bodied forms suffered severely. 



The collection is an interesting one, and whilst most of the 

 forms are similar to those found further south, there are excep- 

 tions. Two species of T erritellarice, one of the genus Aname, 

 Koch, and the otheF uncertain, were found at Finke River and 

 Hermannsburg, both unfortunately too damaged for descrip- 

 tion, and the Argiopid genus Carepalxis, Koch, occurs in one 

 species. Sparassidce are well represented, but examples of 

 Lycosa are not as abundant as one would expect, probably 

 owing to their subterranean habits. 



The following is the list of species determined : — 



TERRITELLARI^E. 



Aviculariid^e. — Aname, sp. Hermannsburg. Idioctis 

 jpalmarum, Hogg. Finke River. (A damaged specimen may 

 be this species recorded from the same locality, Horn 

 Expedition.) 



CRIBELLAT^. 



DiCTYiDiE. — A.maurobius robusti/s, Koch. Finke River.
