552 ON A COLLECTION OF LAND AND FRESH WATER SHELLS, 



River Dee, Torsdale on Prospect Creek, and Prairie Station on 

 Kroombit Creek. Crossing to the Burnett watershed Cania was 

 reached, the Three Moon Creek, Cania Station and Dalgangal 

 passed in succession, and the traveller arrived at Gayndah on 

 November 10th. Thence a course was shaped via Banban on the 

 Barambah River, Boobeyjan and Kilkivan to Gympie. Two 

 localities in this neighbourhood were searched and will be quoted 

 in the following list as (a) a scrub nine miles north, and (b) 

 another scrub at Blackfellow's Creek, twenty-seven miles south 

 of the town. In continuation of the journey the Mary River was 

 followed from Kenilworth to its source, and the summit of the 

 Blackall Range attained by way of Canondale. After passing 

 Durundu and Caboolture a trip was made up the North Pine 

 River, and the rich scrubs around Mt. Mee were examined. 

 This tour was then concluded, and Brisbane reached on Decem- 

 ber 6th.
