The following material was collected by the author 

 during his tvvo expeditions or. the Australian continent. 

 It comes chiefly from the dry desert-like country in the 

 Kimberleydistrict of Northwest Australia and from the 

 rain-dripping jungles or rain-forests in Queensland. Smaller 

 collections were also made during my travels from west to 

 east during my more temporary visits to Southwest Australia, 

 New South Wales and the southern parts of Queensland. 



The material comprises not less than 230 bottles and 

 tubes, and is undoubtedly the largest and most comprehen- 

 sive material ever collected from the Australian continent. 

 It contains no less than 51 different species belonging to 

 12 different genera. Of these about 85 % or 36 species are 

 new, thus bringing the number of known species from 44 up 

 to 80. Only one genus has proved to be new. In addition,
