770 REVISION OF THE AMYCTERIDES, iv., 



other respects from the other members of the group. S. horridus 

 also possesses the main characters of this group, but is so different 

 in many respects, that I have not included it, but treated it as an 

 anomalous species. 



I have seen a large number of specimens from different localities 

 in New South Wales, which belong to this group, but which were 

 mostly represented by single specimens. They showed considerable 

 variation, inter se, and from any of the described species. I have 

 not had sufficient material, however, to determine the range of 

 variation, and have, therefore, described only the most outstanding 

 forms. I think, however, that the group will be found to be a 

 much larger one, when the mountain-ranges, particularly in the 

 southern portions of New South Wales, have been properly 

 worked. 



A species, that occurs commonly on the Blue Mountains, has 

 been identified by Macleay as S. elongatus Bohem.
