104 Hotzicx: Fosstr Perat aND Fruit From Kansas 
The fruit is plainly that of a fig, and although some twenty- 
three species of Frcws have been described from the Dakota group 
they were based upon leaf-impressions alone. Only two speci- 
mens of fruit were known and these were too ill-defined to admit 
of specific description. (‘‘ Fruits of Ficus,” Lesq. Fl. Dak. Group, 
85. pl. ro. f. 7,8. See our Fig. B, 2, 3.) They are incidentally 
mentioned however as being associated with leaves of Ficus tnae- 
gualis Lesq. 
Specimens considerably more satisfactory were described and 
figured by Heer in 1874, from the lower Atane beds of Green- 
land — representing a geological horizon which is practically the 
equivalent of the Dakota group — under the name Ficus protogaea 
wicer* (Pl. Poss. Arct. 3°: 108. p/. 30. f. 5-7. See our Fig. B, 
m.5.033 
Fic. B. 1. Ficus neurocarpa Hollick. 2, 3. ‘ Fruits of Ficus’’ (after Lesque- 
reux). 4-6. Ficus protogaea Heer (after Heer). 
* The name Ficus protogaea was previously used by Ettingshausen, in 1867, in de- 
scribing a fragmentary fossi] leaf from the Cretaceous of Niederschoena in Saxony 
(Sitzb. Akad. Wiss. Wien, Math.-Nat. Cl. 55: 249. f/. 2. f. 5.) In any revision of 
the genus it would therefore be necessary to rename these fruits. In this paper how- 
ever it is not thought necessary to do anything more than to call attention to the fact.
