It appears to represent a seed with an indurated outer coat. It 

 is almost perfectly fusiform in shape except for a slight flattening of 

 the sides which give it a trigonal cross section. Ends about equally 

 bluntly pointed. Length, 2.25 centimeters; maximum diameter, in 

 the middle, about 8.5 millimeters. No structural details can be 

 made out. 



There is some resemblance to the seeds of the Sapindaceous genus 

 Talisia Aublet, but this is not especially marked and probably with- 

 out significance. I have no doubt but that with more extensive 

 comparative material its relationship could be determined. 



It comes from the middle Eocene between Arroyo Mancaniajor 

 and Ovejas, Department of Bolivar, and was collected by R. L. 

 Bechelaymer.
