258 RECOKDS OF THE AUSTRALIAN :MrSEUJI. 



Abdomen. — Obovate, dark-brown, clothed witli long haii'S ; 

 plates of pulmonary sacs larg-e, yellowish-brown ; the large 

 chitinous plate in front of I'i lua epii/usteris je\\owi^h-hvovfnR]so, 

 hair}", and having two large, lateral depressions. 



Spinnerets. — Yellow, hairy; superior mammillfe, less than 

 half the length of cephalothorax ; third joint longest, second 

 shortest ; inferior mammilla? short, and close together. 



Obs. — It may be necessary, hereafter, to erect a new genus 

 for the reception of A. foniildabilis, but as up to the j)resent 

 time males of previously described species of the genus Atrax 

 are unknown, I hesitate to do so at this juncture. 



Hab. — Richmond River, New South Wales. 



Groxp PSEUDATRACE^. 



The species hereunder described is a very interesting form. 

 It was collected by Mr. S. J. U. Moreau, when stationed at An- 

 tonio in charge of the public school there. This gentleman was 

 successful in obtaining two specimens, both females — one 

 mature, and the other about half-grown. These specimens 

 have lain in our collection for some time, awaiting an opportu- 

 nity of being worked out. Whilst engaged upon the study of 

 this material my attention was called to another example, col- 

 lected by Mr. John Braziei", near Xarrabeen. This was also an 

 adult female, and although decidedly bleached, was otherwise in 

 good order. The specimens collected by Mr. Moreau were 

 presented b}^ liim to the Trustees. 



For the reception of this species, which I name Fseudatncv 

 moreaui, it appears necessary to found not only a new genus, 

 but also another group or section, to which I give the name 

 Pseudatracepe. Furthermore, just as I was concluding the 

 present paper, another Territelarian came to hand, and for its 

 reception another group or section is also required, as also an- 

 othergenus. For the former 1 proposethe namePoikilomorphite, 

 and for the latter, Foikilonioqdiiii. Hogg-*-' has given a table 

 in elucidation of the groups as they were known, at the date of 

 its publication, to occur in Australia and New Zealand. They
