Introduction. 



There has recently been presented to the Peabody Museum 

 at Yale University a slab of sandstone containing the impres- 

 sion of a small fossil whale, apparently one of the Delphinidse, 

 but otherwise new to science. It was found by Mr. Edwin 

 White New hall, Jr., of the ISTewhall Land and Farming Com- 

 pany, San Francisco, and presented by him to the Peabody 

 Museum through the intermediation of the writer. In view of 

 the scarcity of cetacean remains from the Tertiary rocks of the 

 Pacific coast, and of the perfection of the relic, the specimen 

 is eminently worthy of consideration.
