Type species, P. regina L. Koch. 



This genus was formed by M. Simon in 1880 for L. Koch's 

 Heteropoda regina from Queensland, and Thorell soon after picked 

 it out for a new genus which he called Polydamna, from Yule 

 Island, Torres Strait. Apparently the only male known is 

 described by the latter, and his description of the male palp with 

 four spirals confirms my belief that it belonged to this group and 

 not to the Heteropodese, to which it could be ascribed only by the 

 length of the median eye-space. 



My Isopeda horni (Horn Exp. vol. ii. Zool. p. 340) really be- 

 longs to this genus, and two more species in the British Museum 

 now bring up the number to four. The whole eye-space is 

 raised up on a low fiat tubercular region. The legs are rather 

 short and thin, the two front pairs being of equal leng-th. The 

 rear row of eyes is slightly procurved, the eyes being about equal 

 in size ; the front row straight or recurved, with the eyes either 

 equal or the laterals slightly larger. The median eye-square is 

 clearly longer than broad. 



The species can be distinguished as follows : — 



a. Front row of eyes equal in size. 



ai. On underside of abdomen a black lunate transverse 



stripe behind epigyne and similar smaller stripe in 



front of spinnerets; intermediate space bright 



reddish brown. Cephalothorax 6 to 7 mm. in length. 



One spine on tibia iii. and iv. above regina L. K. 



h^. An ill-defined dark patch behind epigyne ; no stripe 

 in front of spinnerets; intermediate space dull 

 yeUow-brown, with irregular dark spots. Cephalo- 

 thorax about 10 mm. in length. No spine on tibia 



iii. or iv. above liomi Hogg. 



J. Front lateral eyes larger than median. One spine 

 on tibia iii. and iv. 

 c'. On the underside of femora i. and ii. bright red 

 hair. Cephalothorax about 10 mm. long. Eyes 



bright orange tenuis, nov. sp. 



<£!. Underside of femora yellowish brown, dark, hairy. 

 Cephalothorax 6 to 7 mm. long. Eyes black. Three 

 teeth only on outer side of falx-sheath occidentaJix, nov. sp.
