The facies of tlie fauna approximates more to that of sulitropical and 
temperate West Australia than to any other part of the continent, and is in 
strong contrast with the highly differentiated fauna of tropical and subtropical 
Queensland, situated to the east of the Cordilleras, to which it is geographically 
equally near. The limited number of genera represented, together with the facts 
of their geographic distribution, would seem to indicate a primitive population, 
which has been maintained in an isolated condition by climatic and geologic 
changes. 
The genus Microphyura has hitherto been diagnostically known by its unique 
type-species, Helix zuicrophis, Crosse, from New Caledonia. Mr. C. Hedley 
considers it to be an Antarctic constituent in our fauna.
