472 ON CARADID.^ FROM WEST AUSTRALIA, 



Mots * Drimostoma australis, Casteln., D. montann, Casteln., 

 and D. alpeatris, Casteln., seem tome to be species of Tropopterus, 

 so that genus must now be considered as belonging also to the 

 Australian fauna. D. thouzeti, Casteln., and D. vicina, Casteln., 

 are species of Abacetus I believe. D. tastnanicufi, Casteln., I do 

 not know. D. antavctica, Casteln., (type in Howitt Coll.), is 

 doubtless a species of Tropopterus. In the tabulation of the 

 group Amblytelides, I have followed the Rev. Thos. Blackburn, f 



Genus Cyclothorax.
