 ton. There has been no excavation made, as yet, to uncover 

 other portions of the skeleton, but Mr. Wellington has prom- 

 ised to have it done, and to secure as much of the skeleton 

 as possible, for the Society's collections. 



The small teeth were found about five feet below the sur- 

 face in the solid cement, by some parties that were digging a

BY WM. M. GABB. 



Through the kindness of Misa Errington, of Bear Valley, Mariposa County, 

 I have had the opportunity of examining a series of fossils, discovered by that 

 lady on the Mariposa Estate. The shells appear to be of Jurassic age. The 

 genera so far recognized, are Belemnites, Nucula or Leda, Lima, Pecten, and 

 Pholadomya. The following are sufficiently perfect for description. Fuller 

 descriptions and figures will be published hereafter in the Geological Report 

 of the State.
