350 NOTES ON AUSTRALIAN LAND-PLANARIANS, 



These four species, we believe, include all the Australian Land- 

 planarians at present described. 



For some time past we have, both jointly and independently, 

 collected planarians from the neighbourhoods in which we reside, 

 and from such places as we have been able to visit during 

 vacations. In this way we have obtained specimens from various 

 places in the County of Cumberland, from the Blue Mountains as 

 at Springwood (1,200 ft.) Hartley Vale and Mount Wilson 

 (3,400), from near Capertee (2,600 ft.), and in the Capertee 

 Valley, from various localities in the Mudgee District where one 

 of us is resident, and from Burrawang (2,000 ft.). Though we 

 have been able to go further afield than Mr. Moseley's short visit 

 permitted him to do, yet relatively to the area which planarians 

 may reasonably be supposed to inhabit even supposing this to be 

 chiefly the coastal districts, we have, after all, only been able to 

 glean in a few places. Nevertheless we have now obtained 

 sufiicient material to enable us to describe a number of new 

 species, to announce the occurrence of a second genus characterised 

 by the possession of two eyes, hitherto unrecorded from Australia, 

 and to adduce reasons for merging the genus CcBnoplana of 

 Moseley in Geoplana, F. Miill. Tn addition the Hon. William 

 Macleay has kindly allowed us to examine the planarians in his 

 Museum ; Mr. Olliff has given us specimens of two species from 

 the Hunter River district, and Mr. Froggatt specimens of another 

 species from Victoria, so that we are able to add some 

 particulars about geographical distribution. Finally we have to 

 thank Mr. Masters for a quantity of material obtained from one 

 of the Sydney nurseries. 



Of the sixteen species of which we have now examined 

 examples, not one of them can be referred to the genus 

 Cmnoplana of Moseley. Six of them are characterised by 

 the possession of two instead of many eyes, and, pending histo- 

 logical examination to which we have not yet been able to attend, 

 they are referred to the genus Rhynchodemus of Leidy. The 

 other ten may be referred to the genus Geoplana as at present 

 defined.
