 lateral eyes of rear row large, somewhat elliptical, of equal size to those of 

 the front pair, oblique and slightly liiised on black rings ; front eyes 

 separated from each other by a .space equal to once-and-a-half their indiv- 

 idual diameter, and from their median neighboui'S by a space equal to 

 about that of one diameter ; median eyes round, small, and separated from 

 each other by a space equal to about once their own individual diameter ; 

 rear median eyes round, smaller than the foregoing, widely removed from 

 each othei' ; each is also separated from its lateral neighbour by a space 

 equal to rather more than once its own diameter (PI. xxi., fig. 55). Legs. 

 — Yellow-brown, short, sturdy-, thickly clothed with long, coarse bristles, 

 but displaying- naked areas; each tibia and metatarsus armed with rather 

 long, moderately strong spines ; co.xse long, hairy ; metatarsi and tarsi i. 

 and ii. thickly scoi)ulated ; relative lengtlis : 4, 1, 2, 3. Palpi. — Similar 

 in colour and clothing to legs ; tibia and tarsus bespined ; the latter 

 thickly scopulated. Falces. — Projecting well forward, shining, mahogany- 

 brown, densely clothed with long, coarse bristles, but displaying naked 

 areas; rasfellunr consists of a series of strong teeth spread over a rather 

 extensive area ; inner ridge of the furrow of each falx armed with seven 

 strong teeth, and the outer with six ; in addition to these there is an inter- 

 mediate row consisting of about a dozen smaller teeth ; of the latter those 

 nearest the base are the smallest. Maxilhv. — Long, broad, arched, hairy, 

 reddish-biown, heel well rounded, apex of inner angle projected forward, 

 and terminating in an obtuse point; lower portion of inner angle fringed 

 with a beard of long, yellow-grey hairs, and the upper with a beard of red 

 hairs. Labium. — Concolorous, shining, arched, free, broader than long, 

 submerged beneath maxillae, apex procurved, and fringed with coarse 

 bristles. Stern luii. — Pyriform, elongate, yellow-brown, moderately arched, 

 hairy, terminating in a sub-acute point between fourth pair of coxae ; 

 surface clothed with long, coarse bristles ; anterior sigilla marginal, inter- 

 mediate pair submarginal, posterior pair large and removed from margin. 

 Abdomen. — Obovate, slightly overhanging base of cephalothorax, yellow- 

 brown, arched, hairy. Spinnerets. — Short, stout, hairy, concolorous ; first 

 joint of superior pair much the longest, and the third minute and dome- 

 shaped ; inferior spinners somewhat coniform, and separated from each 

 other by a space equal to about one-half their individual diameter. 



Obs. — This is the second s[)ecies recorded to the genus Gains, Rainb. 

 The first one came from Minnivale, West Australia, and its trap-door was 

 recorded by Mr. W. B. Alexander, as being thin, of the wafer type, but 

 having a few twigs incor|)orated in its upper surface round the edges. ^ In 

 respect of the genus itself its natural position should be immediately 

 after Anidiops, Pocock. 



Hab. — Port Augusta (July, 1909), South Australia.
