NOTES AND EXHIBITS. 



Baron Maclay exhibited a sketch of a new species of 

 Heterodontus, recently received at the Australian Museum from 

 Japan, and pointed out the marked differences between it and 

 Heterodontus Phillippi, the species with which the Japan Fish had 

 hitherto been confounded. He suggested for it the specific name 

 of japonims, and said that he would give a detailed description of 

 it at the next meeting of the Society. 



Mr. Macleay exhibited in illustration of Mr. De Vis's Paper, casts 

 of a gigantic humerus of a Diprotodon, and a smaller humerus, 

 probably of Nototherium. The fossils were both from Darling- 

 Downs. 



Mr. Thomas Whitelegge exhibited under the microscope a living 

 specimen of the species of Fredericella, one of the fresh water 

 Bryozoa which had not previously been noticed in New South 

 Wales. It appeared to be identical with the European F. 

 sultana, of Blumenbach,
