added a short note to the effect that C. novw-hollandiai was taken 

 at Sydney by Mr. Bradley, but that he found no web; the speci- 

 mens collected by Mr. Bradley were captured from shrubs and 

 plants. [6*. novce-holhindice wurde von Mr. Bradley bei Sydney 

 gefunden; nach den Notizen desselben verweilte das Thierchen 

 bewegungslos an einen Zweige und hatte kein Gewebe ; Mr. 

 Bradley erhalte es audi durch Klopfen von verschiedenen Strau- 

 cher und Pilanzen.] It will be seen, therefore, that, according 

 to the observations of Mr. Bradley and myself, the Australian 

 forms of this genus, at any rate, are of arboreal habits. 



Of the Argiopidce, two new species of Araneus are described; 

 of these, A. singularis is a very remarkable and interesting form; 

 the other (A. parvulus) is normal. Lastly, a variety of Cam- 

 bridge's Dicrostichus fnrcatus (var. distinctus) is recorded and 

 described.

£. Cephalothorax 5 mm. long, 4 mm. wide; abdomen 7 "3 mm. 

 long, 4 mm. wide. 



Cephalothorax longer than wide, ovate, dark mahogany-brown,

Eyes six, compactly grouped, arranged in two rows, and in the 

 form of a small, transverse oval; the pair comprising the anterior 

 row are somewhat the largest, and are separated from each other 

 by a space equal to about twice their individual diameter; the 

 second row (four) is strongly procurved, and of these the median
