Attached by M. Simon to the genus Acantliodon and group 

 Idiopeo', to which the position of its front side-eyes entitles it. 

 The rear side-eyes are, however, at least twice the diameter of the 

 front middle instead of nearly equal, and the lip broader than 

 long, instead of equally so. No spines on lip, instead of a row of 

 a few large ones. I think, therefore, that Mr. Pocock is right in 

 restoring Ausserer's genus.

This, the only species of the genus, was described originally 

 from a male from Perth, W.A. However, a female was received 

 by the British Museum from the same neighbourhood a few years 

 since, from which I have taken the following few points in addition 

 to those published by Mr. Pocock.
