Tlie Fossil Plujllopoda of the Palceozoic Bochs.- — Ttrelfth Report of the 

 Committee, consisting of Professor T. Wiltshire {Chairman^, Dr. 

 H. Woodward, and Professor T. Rupert Jones (Secretary). 

 {Brawn up hy Professor T. Rupert Jones.) 



1§. A SHORT provisional list of the Silurian Peltate Phyllopods was appended 

 to our Report (the Tenth) for 1893 ; but since then a complete catalogue 

 of the Lower Palaeozoic Phyllopoda (Phyllocarida), with their geological 

 horizons, their range and localities, has been made with the obliging help 

 of Dr. C. Lapworth, F.R.S. This is now produced in four tables, as it 

 greatly enhances the value of our Reports on these fossils, and will be 

 of considerable use to paleontologists both at home and abroad.
