494 Berry — Engelhardtia from the American Eocene. 



The writer has collected leaves of Engelhardtia in these 

 deposits, but since their exact relationship with the fruit is 

 unsettled they will not be considered at the present time. The 

 species, which is new, may be called 



Engelhardtia ( Oreomunnea) mississippiensis sp. nov. 



Description. — Involucre large, trilobate, somewhat refiexed. 

 Aire widely spreading, the angle between the median and

lateral wings being 70° to 80°. Sinuses correspondingly open, 

 rather straight-sided, rounded at the angle, which is l'5 cm from 

 the extreme base of the specimen. The median wing is the 

 longest of the three and is equilateral, spatulate or oblanceo- 

 late in outline, expanding gradually distad from a basal width 

 of 8 mm to a width of 13 mm , where the distal portion is broken 

 off, 5 cm above the base. Since this apical part is missing the 

 total length is estimated at 6"5 cm , which is a minimum rather 

 than a maximum estimate. Lateral wings slightly inequilateral, 

 the outer part of the lamina being a trifle wider than the inner. 

 Aj)ex rounded. Length 5 cm . Greatest width, which is above 

 the middle, ll mm . Least width proximad, 7 mm . Primaries 

 three in number, one median primary being present in each 

 wing. The primaries are relatively very stout and continue 

 with but slight attenuation to the tips of the wings. No sub- 

 ordinate primaries or discordantly directed secondaries are 

 present as in some of the European Tertiary species.
