Ananchytus ovatus, Galerites albo-galerus, Etheridgia mirabilis, &c, 

 &C, all from the greensand rocks that formed once the bottom 

 of a sea in which sharks and other creatures abounded. Some of 

 the sharks' teeth were found on Saturday in the beds now form- 

 ing the site of the reservoirs. The best find was a striated tooth 

 from the chloritic chalk that crops out around the basin. The 

 tooth was a new form to the members present, and will probably 

 prove an addition to our list of fossil fauna.
