Loc. Western Australia (Freeraantle, Perth, Swan River). 



In the monograph of the species of this genus published in 

 1888 I referred to some specimens of what T supposed, and 

 still suppose, to be novce-hollahdice^ Peters, in the British 

 ]\luseum, ticketed " Ceylon." That the locality is erroneous 

 has been to my mind settled conclusively by the subsequent 

 discovery in the Museum of some specimens of a Centipede 

 {Cormocephalus ourantiipes, Newp.), which is apparently not 

 uncommon near Perth, also bearing the label "Ceylon," accom- 

 panied by the same register number as that under which the 

 scorpions were entered. 



1 am not acquainted with any evidence that this species 

 ranges far from the south-western corner of Australia. A 

 specimen from Port Lincoln that I at one time referred to it 

 is the young of another species.

 broad, the fifth more than twice as long as broad ; the supe- 

 rior crests weakly granular, not posteriorly elevated ; inferior
