Part i. — Descriptions of new species, etc. 



Since the publication of my previous paper on Australian Land 

 Planarians (n, p. 1U4)* I have obtained several interesting un- 

 described species, descriptions of which, with other notes, are 

 contained in this paper. 



For specimens of the following species from Western Australia 

 I am indebted to Mr. Chas. G. Hamilton, who collected and sent 

 them to me preserved in spirit. They are of particular interest 

 as being the first x-ecorded land planarians from that part of 

 Australia, and from the fact of two of the species being found 

 living in a dry sandy district which would be considered extremely 

 unfavourable for such creatures. 



In describing these land planarians I have thought it best to 

 adhere to the old generic classification in the meantime, though 

 Prof, von Graff, in his recently published great monograph of the 

 group, (12) has proposed the new genus Artioposthia for a number 

 of species which have hitherto been included in the genus 

 Geoplmia. 



Some points in Graff's arrangement of these may require 

 modification, through, amongst other reasons, his not having had an 

 opportunity of examining specimens of some of the species. At 



"The numbers in brackets refer to the Bibliography at the end of the paper.
