492 SOME NEW ARANEIDvE OP NEW SOUTH WALES, 



Genus Dicrostichus, E. Simon. 

 Dicrostichus furcatus, Camb., var. distinctus, var.nov. 

 Cyrtarachne furcata, Cambridge. 



This species was described and figured by Cambridge in 1877,* 

 from a specimen collected at Parramatta. Some time ago, 

 Master Clark, son of Dr. Clark, North Sydney, collected a 

 specimen, which is unquestionably a variety of D. furcatus, an 

 example sufficiently differentiated from the typical form to 

 warrant description. 



In the form under consideration all the parts except the 

 abdomen agree with Cambridge's description. In Cambridge's 

 specimen, the abdomen is described as having on the upper side 

 "some not very large, bluntish, conical protuberances; two of 

 them are in a straight transverse line, wide apart towards the 

 fore margins; the rest, eight in number, are arranged in a some- 

 what circular group at the posterior extremity." 



Upon the upper surface of the form collected by Master Clark 

 there is near, and in front of, the two anterior protuberances, a 

 large, broad, transverse depression, which is much the deepest 

 laterally; the tubercles are located near the centre, straw-yellowish 

 at the base, and the apices mahogany-brown; between the pro- 

 tuberances there is a short transverse ridge, the sides of which 

 slope sharply backwards, eventually terminating in two deep 

 round punctures or pits, the depths of which are dark brown; 

 the punctures just described are widely separated, although some- 

 what closer together than the anterior tubercles; in a line with 

 these there is on each outer margin of the superior surface a 

 smaller but rather deep puncture; below the median pair again, 

 and rather closer together, there are two more punctures, equal 

 in size and depth to the lateral pits; at the posterior extremity 

 there is a group of nine protuberances ; of these, three are 

 arranged in a slightly procurved row, and nearly encircled by
