om'ing), and the Lutetian or Auversian stages of the stanrlaH 

 European Eocene section. 



Thie present species can be exactly matched hy the fruits of 

 several existing species of this large genus, but its great age is 

 undoubted proof that it represents a distinct and extinct botan- 

 ical species, and it is therefore described as such. It may be 

 called Cellis bolivarensis in allusion to the De]:artment of 

 Colombia where these Eocene deposits occur, which name in 

 turn commemorates the great South American liberator.

The si:)ecies may be somewhat incompletely characterized as 

 follows: 



Stone of a drupaceous fruit, of relatively small size, nearly 

 spherical in form, shortly acuminate tipped distad. Polar 

 diameter slightly longer than the equatorial diameter. Di- 

 mensions: Length 5.5 mm., equatorial diameter 4 mm. in one 

 direction and 5 mm. at right angles to the minimum diameter, 

 the difference being probably due to a slight amount of deforma- 

 tion during or subsequent to fossilization. There are four equally 

 spaced smooth and slightly angular longitudinal areas dividing 

 the stone into quadrants, and uniting to form the acurninate tip 

 and the slight prominence at the chalazal pole. The surface of 

 each quadrant is conspicuously pitted, though scarcely meriting 

 the term rugose, by about twenty well distributed rounded de- 

 pressions or pits. These v^ary somewhat in size and outline, and 

 are separated by rounded ridges, which, however, do not pro- 

 ject above the general surface of the stone.
