burrow is seven inclies deep, and at fonr inclies fVom tlie to}) the closing 

 mechanism is fixed. This is formed by a caff of web, free at tlie top, fixed 

 below, and weighted on one side by a flat-sided or hemisplierical pill of 

 earth, which, when the burrow is open, is fitted into a hollow in its side. 

 When, however, the cuH' is jmlled down from below, the pill falls over and 

 forms an effectual door to the lower part of the tube. This is more 

 effectual as a protection than the .surface lid, which is not wholly secure 

 against predatory wasps. It is singular that we find the occurrence of 

 the Territellarife found in the Mount Lofty Ranges much influenced by 

 the geological and forest conditions. The gritty clay of the stringy bark 

 country (Encahiptux (uiplteJI((tti) being i]i our experience much richei' than 

 the open forest country with its sparse undergrowth. The agricultural 

 areas or grass plains to the north of Adelaide, extending about one hun- 

 dred and tiftj- miles, have not been exhaustively studied, but many species 

 are recoi'ded from Booboorowie (near Burra), Yarcowie, Cauowie and 

 Mallala ; the last named place, perhaps, giving the best idea of the deni- 

 zens of the open Mallee scrubs. 



In the winter of 1910, one of us [R.H.P.] spent several days at Pichi 

 Richi Pass, a gorge in the Flindei's Ranges, between Quorn and Port 

 Augusta. This was found to yield a good number of species, including the 

 largest South Australian Territellarian, Selenocosniia stirlinyi, Hogg. This 

 species lives in deep burrows and spins a hymen like the Anames. The 

 large A name grandis is also found there. This constructs a bui-row iden- 

 tical with that of Selenocosmia, with a hymen. 



Bluhistonla atn-ea, Hogg, also extends its limits northward to the 

 Flinders Ranges, where it is found in company with Ai/nnippe suhtristis, on 

 the banks of the Pichi Richi Creek at Wool Shed Flat. In 1910, this 

 gorge was an excellent hunting ground for all sorts of Araneids, but it 

 was noticed in passing through on January 1st, 1918, that the foothills 

 and gullies, formerly visited [R.H.P.] were covered with wheat fields and 

 nearly all the mallee scrub removed. 



The Pichi Richi Pass opens out on the plain at the head of Spencer's 

 Gulf, near Port Augusta. The country round the head of the Gulf was 

 visited in the same expedition. This country is largely sand, with samphire 

 flats, covered with Kochin, Suhola, blue bush and salt bush. Besides 

 Territellari^ there are several species of lid-building Lycosas, some of 

 which build a firm collar to hold the lid, and having a primitive hinge. 

 Species that do not build lids in this country would be exposed constantly 

 to the danger of having their buri'ows filled with the dinft from sand 

 storms. 



The best field found in the vicinity of Port Augusta was a samphire 

 flat to the east of the town. There wei'e found Ajaii.lppe rohusta, sp. nov., 

 AnicUops manstridgei, Pocock and Uatns hirsutns, sp. nov. The latter, 

 which is rare, sometimes reaches a large size and a giant specimen, 

 undoubtedly of considerable age, had a burrow about twelve inches in 

 depth, over a quarter of which was packed the debris of food, chiefly parts 

 of Coleoptera. 



The burrows and lids of this species, as of that of Aii,idioph-, do not 

 shew great variation from the Ctenizid type, i.e., a thick lid of alternate 

 layers of earth and web, like a gun wad, with a well constructed hinge.
