The specimens upon which the present notes are founded were 

 collected for me by Mr. Thos. Steel at Blackheath and Wentworth 

 Falls, and were sent to me partly alive and partly in spirit, 

 together with notes on the living animals. I wish to express my 

 most sincere thanks to Mr. Steel for the great amount of time 

 and trouble which he has expended in obtaining the specimens, 

 which I particularly desired for the purpose of comparison with 

 the Victorian species. In all nine species were obtained, of which 

 seven are known to be represented in Victoria by identical or 

 slightly varietal forms. Of the two remaining one has been 

 found in Tasmania (6'. variegata), anfl has therefore probably as 

 yet simply escaped observation in Victoria, while the other {R. 

 moseleyi) is represented in Victoria by a closely allied if not 

 specifically identical form {R. simidans). The most interesting- 

 forms in the collection are varieties of Rhynchod emits victories 

 and Geopln)ia fl etcher I, which seem worthy of varietal names, 

 while a variet}^ of the Victorian G. quadrangulata is also abun- 

 dant. None of these three species have hitherto been recorded 

 from New South Wales. The remaining six species are already 

 more or less well known in New South Wales from the writings 

 of the late Professor Moseley and Messrs. Fletcher and Hamilton. 



I have at length ventui'ed to revise the nomenclature of the 

 common and widely distributed Geoplana sanguinea, which has 

 been described under a different name by nearly every writer who
