BY R. H. CAMBAGE. 591 



I wish to acknowledge assistance in various ways from Mr. J. 

 H. Maiden, F.L.S., who has been ever ready to discuss with me 

 any knotty points which have arisen in regard to the identification 

 of plants, and, in addition to naming many of the species, to give 

 any information that might add to the usefulness of these papers. 



My thanks are also due to Mr. R. T. Baker, F.L.S., who has 

 also contributed in an exactly similar manner. 



I also desire to acknowledge services rendered by Mr. E. 

 Betche, Botanic Gardens, Mr, W. S. Dun, Palaeontologist Mines 

 Department, Mr. J. J. Fletcher, and Mr. H. G. Smith, F.C.S.
