justify the Council in making the award. I wish to draw special 

 attention to the very valuable list or census by Mr. Whitelegge, 

 of the { * Marine and Fresh- water Invertebrate Fauna of Port 

 Jackson and its neighbourhood," as it is, I trust merely the fore- 

 runner of other papers dealing with similar matters. Although 

 it is impossible to make catalogues of this character complete in 

 the first instance, members should not thereby be dissuaded from 

 making a commencement, for work of that kind "begun, is half 

 done " since it is comparatively easy to correct and add to a census 

 but much time and courage is required to initiate a laborious 

 work of that kind.
