There is one female from Kangaroo Island. 



Nephila adelaidensis, n. sp. 



Female. — The cephalothorax is yellow-brown, thickly 

 ^covered with silvery-grey hair.' Three pairs of black side 

 spots, one median, and a pair of black prominences. Mandibles 

 chocolate-brown, darker at the anterior end. Fangs the 

 same. Lip, maxillae, and sternum medium yellow-brown, 

 lighter at the edges of the former and on the humps of the lat- 

 ter. Thick, rough, silver-grey hair on the sternum. The legs are 

 yellow-brown, with fine silver-grey hair on the under-side, 

 rather darker at the anterior half of the tibial joints. The 

 hair on the anterior half of the metatarsi and on the tarsi 

 is dark-brown. The abdomen is yellow-grey above, with 

 silver-grey, fine, down-lying hair all over. On the under-side 

 it is dark-brownish-grey, with paler transverse and longi- 

 tudinal stripes, forming a rhomboidal figure below the genital 

 aperture. The spinnerets and epigyne are the same as the 

 ground colour. 



The general points of this species agree with N . meridion- 

 alis above. The cephalothorax is one and a half times as long 

 as tibia iv. The rear row of eyes is straight, the front re- 

 curved. The eyes themselves are all about equal in size : the 

 front median, however, slightly larger than the rest. The 

 laterals are a little more than their diameter apart on a 

 common prominence; the front and rear median one and a 

 half times the diameter of the front eyes apart. The clypeus 

 is the same in width. The legs are slight, and only moderately 

 long; without spines. Short, thick hair on the metatarsus 

 and tarsus of all legs. Fine hair on the under-side of the 

 remaining joints. The patellar joint of the palpi is shorter 

 than the tibial joint. The abdomen is straight in front, 

 rounded at the corners and sides, tapering to the posterior 

 end. 



This species differs from N . rneridionalis in its shorter and 

 finer legs, its more oval abdomen, lesser distance between side 

 and median eyes, want of plumose bunches on the legs, and 

 lighter ground-colouring of the cephalothorax. The epigvne,-
