In the following section we have remarked'upon the noteworthy features of 

 all fossils obtained by us from Currabubula and the shelly ridge in 'the south-east 

 of the parish of Babbinboon, and also the extensive collection from the latter area 

 presented to us by IVfrs. Scott, to whom we are greatly indebted. The opportunitv 

 has heen taken to examine also the undescribed fossils in the collection of the Aus- 

 tralian Museum and that of the Geological Survey which were obtained in the 

 region around Carroll, Somerton and Babbinboon. chiefly by Mr. Donald Porter, 

 and the late Charles CuUen . We are thus able to gi\e a list of the known forms, 

 including critical descriptions of five forms previously known in the State but 

 only from provisional determinations* seven new records for the State, and fifteen 

 species and three varieties which we believe to be new. We are indebted to Pro- 

 fessor Lawson, D.Sc. and Mr. Chapman for the description of several of the fos- 

 sils. Apart from the leaf impressions of Rhacopteris, Aneimites and Archaeo- 

 cala mites in the Kuttung, which do not call for special notice, two silieitied plant 

 remains are noteworthy. They were found on the eastern slopes of Mts. Cobla 

 and Sugarloaf, three miles east of Currabubula. Professor Lawson describes
