 Plates xx\qii-xxxi. 



During December, 1915, and January, 1916, Mr. A. M. Lea, of the South 

 .Australian Museum, \isited Lord Howe and Norfolk Islands. Among the 

 .material collected by him were one Opilionid and a number of Araneads. 

 Naturally many known forms are included, but in addition to these, new ones, 

 some of which are particularly interesting, occur. 



[When the paper was being edited for the press it was discovered that the 

 manuscript of the genus Clubioiia was missing. As "Sir. Rainbow had died in 

 the meantime, inquiries for it were made in Sydney, but proved fruitless. Tiiree 

 species had been named and figured, and, as we possess the type specimens, Dr. 

 Robert Pulleine kindly undertook to furnish the requisite descriptions: Clubiona 

 vcnatoria, C. asbolodcs, and C. decora will therefore stand under the authorship 

 of Rainbow and Pulleine. 



Types of all new species are in the .'^outh .Australian Museum. 



The letters L.Td.L and N.I.. following the names of the species, indicate, 

 respectively, Lord Howe and Norfolk Islands. — Ed.]
