Zoogeographical considerations suggest that Kaup, in his effort to reduce the 

 number of species of Aulacocyclus to five, regarded two distinct forms as one when he 

 merged A. percheroni in A. rosenbergii. This course has, however, been followed by 

 all subsequent authors, except perhaps Blackburn, most of them omitting any refer- 

 ence to the locality of the type specimens of A . percheroni. 



' Kaup gives "Trisbane," Ijut Geniniinsier and Harold are presumably right in regarding thi-^ 

 as a misprint for Brisbane.
