reasons for not accepting entirely the classification of them proposed 

 by Captain Spratt, and followed by Earl Ducie in his Geological Map 

 of the Maltese Islands. He divided the Miocene strata into the 

 following subdivisions: — 1. The Upper Limestone; 2. The Sand 

 Bed; 3. The Marl; 4. The Calcareous Sandstone; 5. The Lower 

 Limestone ; and again subdivided the Upper Limestone into three 

 parts. Dr. Wright gave diagnoses and detailed descriptions of forty 

 species of Echinidce, four of which are new ; and Dr. Adams added 

 a Table showing their stratigraphical distribution.
