356 ARACHNIDAN FAUNA OP BRITISH NEW GUINEA. 



between the Malayan fauna as exemplified in Borneo or the 

 Philippines and in New Guinea. All the characteristic Malayan 

 forms, Atopos, Xesta, Helicarion, Microcystina, Trochnmorplia, 

 Obha, Chlor'itis, Cochlostyla, Pupina and Diplommatina are 

 common to both regions. The Solomon Islands, Fiji, Samoa, etc., 

 appear by the light of the Papuan shells to be inhabited by an 

 eastern extension of this Malayan fauna, which has also over- 

 flowed into Queensland."* The extension of Phrynus grayi from 

 the Philippines to the Papuan region, would therefore appear to 

 be in accordance with the theory put forward by Hedley.
