ON SOME LAND SHELLS COLLECTED TN QUEENS- 

 LAND, BY MR. SIDNEY W. JACKSON. 



By C. Hedley, F.L.S. 



(Plates iv.-x. ) 



Primarily in quest of ornithological material and information 

 and on behalf of Mr. H. L. White, of Belltrees, Scone, New South 

 Wales, Mr. Sidney W. Jackson visited Queensland in 1908. His 

 travels extended through the coastal area, from Brisbane in the 

 south, to Cairns in the north. Some account of his successful 

 journey in search of the Tooth-billed Bower Bird was published 

 in the " Emu."* 



No other part of the continent has so rich a snail fauna as 

 this. Some of the districts travelled by our naturalist had not 

 been searched previously by a conchologist. No opportunity was 

 lost of collecting land-shells, only a few of the large collection 

 gathered, being discussed in the following pages. Among the 

 first fruits which he reaped as a pioneer in new country, are the 

 interesting Panda discovered near Mackay, and the curious 

 Flanispira taken near Atherton. Besides such novelties, the 

 collection affords interesting information on the extension inland 

 of species hitherto considered to be confined to the coast. 



An unusual and pleasing feature of this collection is not only 

 the care with which the specimens have been collected and pre- 

 served, but the sketches and excellent field-notes on habit and 

 environment. Seldom do collectors pay such attention to these 

 important details. 



My cordial thanks for the privilege of studying this interesting 

 collection are offered to Mr. Jackson, who has further added to 

 my obligations by presenting the types of the new species here 

 described to the Australian Museum.
