ISToTHRUs ANAUNiENsis Caiiestrini & Faiizago. 



There has always been some uncertainty with regard to this 

 species, which very closely resembles J}^. sylvestris. On looking 

 over our British specimens of supposed sylvestris, however, we 

 find some wliich agree precisely with the description of anauniensis, 

 being tridactyle and having the abdomen rounded posteriorly, with 

 short spatulate hairs of about equal length. 



This species is therefore for the first time recorded here as 

 British. The diagnosis is complicated by the fact that we find 

 some specimens of undoubted sylvestris which are didactyle, but 

 in no case have we come across a tridactyle specimen of the 

 form characterised by the more trvincated abdomen and filiform 

 hairs of unequal length. The two species are, no doubt, closely 

 allied, but there appear to us good grounds for regarding them as 

 distinct.

(Text-figures 80-89.) 



The Spiders described in the present paper are from the 

 Collection of the S: Australian Museum, Adelaide. I am indebted 

 for the loan of them to the kindness of its Director, Prof. E. 0. 

 Stirling, F.R.S. They were collected, however, chiefly from the 

 north side of the River Murray in New South Wales. 



This important group of roving Spiders ranges in great numbers 

 over every part of the known world, and the main features of the 

 type species, L. tarerdida Rossi of the type genus Lycosa Latreille, 

 are so closely reproduced, even to the pattern on the back of the 

 abdomen, in the raost widely separated countries (in Australia 

 with L. obscura, L. godeffroyi L. Koch, L. hasseltii L. Koch, 

 etc.), that all attempts to divide them into subsidiary genera, 

 until we reach a few less numerous and quite outlying forms, 

 have proved unsatisfactory. Consequently many earlier genera,
