from Portugal, Bohemia, Greenland, Argen- 

 tina, and various Localities in the United States 

 and Canada. It is especially varied in the 

 Dakota sandstone. 



Forms referred to Cocculus De Candolle, 

 Coccvlites Heer, or Cebaiha Forskal are re- 

 corded from the Upper Cretaceous of North 

 America, Europe, and Asia and from the 

 earl}- Tertiary of Greenland, North America, 

 and Europe. It seems probable that some of 

 the forms referred to Unger's genus Daphno- 

 <h in belong to this family. The genus Mac- 

 clintockia Heer, of the Upper Cretaceous and 

 early Tertiary, particularly of the Arctic region, 

 is often referred to this family, as by Schimper. 



Occurrence: Goss pit, half a mile east of 

 Mansfield, De Soto Parish, La.; collected by 

 O. M. Ball.

Heer 18 mentions a Cassia emarginata of 

 Saporta, which would, if valid, necessitate 

 changing the name of this Wilcox species. 

 As near as I can discover, however, Cassia 

 emarginata Saporta was a nomen nudum. It 

 is not mentioned by either Schimper or Schenk, 

 and Saporta appears to have renamed the 

 form Caesalpinites latifolius when- he actually 

 described it. 19

This common middle and upper Wilcox 

 species has not heretofore been found south of 

 Grenada, Miss. It is contained in recent 

 collections from a locality 1 mile west of 

 Clayhatchee, Dale County, Ala.

Dalbergia eocenica Berry, TJ. S. Geol. Survey Prof. Paper 

 91, p. 245, pi. 53, figs. 1, 2, 1916. 



The name assigned to this Wilcox Dalbergia 

 in 1916 is antedated by Dalbergia: eocenica 

 Kttingshausen, 20 based on Protamyris eocenica 

 Unger, 21 and I therefore propose that this 

 species be called Dalbergia. puryearensis, in 

 allusion to the type locality.

The present species is based on casts of a 

 nutlike fruit which appears to be very close to 

 those of a recently described genus that is 

 referred with some doubt to the. family Ica- 

 cinaceae and is based upon three new species 

 of existing arborescent forms of the Central 

 American region. In view of the incomplete- 

 ness of the fossil material and the lack of 

 certainty as to its identity with the recent 

 fruits in all particulars, it has seemed best to 

 propose a new genus for its reception. The 

 name suggested for this new genus implies a 

 relationship with the existing genus. The 

 fossil fruit as restored from casts is a moder- 

 ately prolate spheroid, 2.5 to 3 centimeters in 

 length and about 2.25 centimeters in diameter, 

 broadly rounded proximad and bluntly pointed 

 distad. The ligneous shell is marked by some- 

 what irregular prominent brandling and anas- 

 tomosing longitudinal ridges, connected by 

 low subordinate irregularly transverse ridges. 

 If it was like the existing form it contained a 

 single large seed. 



I have had this Wilcox material in my pos- 

 session for a number of years without any idea 

 as to its botanic relationship. In collecting 

 recent fruits in Panama in 1919 I obtained 

 one which suggested the fossil. In seeking to 

 determine the Panama specimen at the United
