During the last year Baron F. von. Miieller has published a 

 key to the Flora of Victoria, and eight decades of his promised 

 work on the genus Acacia. This is entitled '■^Iconography of Aus- 

 tralian species of Acacia and Cognate Genera, &c." In these decades 

 he has given figures of 80 species hitherto but imperfectly known, 

 or only partially described. He remarks in his preface that the 

 genus contains 300 species of well marked forms, and that it is 

 his object to devote the volume to those native species " of which 

 hitherto no drawings had appeared anywhere." The material for 

 the work has been accumulating for nearly 40 years, partly from 

 his own travels and reseai'ches, and partly through contributions 

 from amateur botanists. No plant has been omitted of which 

 the author does not possess full material for detailed analysis. It 

 is needless to observe that this woi-k is one of the greatest value, 

 because the genus Acacia not only is the largest and one of the 

 most characteristic of Australian genera, but also contains many 

 species highly useful for economical, medicinal or ornamental 

 purposes. 



PALEONTOLOGY AND GEOLOGV AND MINERALOGY. 



Triiobites are the subject of three papers, by M. F. Ratte 

 (p. 95;, Professor Hutton (p. 257). Mr. J. Mitchell (p. 435). M. 

 Ratte further writes on Australian fossils of Salisburia 

 (pp. 137, 159) on the muscular impression of Notomya (p. 139), and 

 on a remarkable example of Conchoidai Fracture in Torbanite. I 

 have added a second note on Platyceps Wilkinsonii with description 

 of two other specimens of probably the same Labyrinthodont
