320 Annals OF the Carnegie Museum. 



Judging by the other distinguishing features given by Lesquereux 

 under his description of Protophyllnm Lcconteanum, I have decided 

 that our specimen fits more closely that of Protophyllnm Sternhergii 

 than it does Protophyllnm Leconteanum. The specimen was among 

 fossils obtained by exchange from the U. S. National Museum, but 

 bore no label. 



Occurrence: Ellsworth County, Kansas (?), Dakota Sandstone 

 (Cretaceous). U. S. National Museum by exchange. Accession No. 

 4799, Carnegie Museum. Pittsburgh, Pa, {No. 56).

Description: Our specimen shows only a fragment of the leaf which 

 gives pretty definitely the outline and veining of the base. It is only 

 about 5 cm. broad near the base. The length, of course, can not be 

 determined. The pelta and veining show rather distinctly, and evi- 

 dently the leaf has been rightly determined by Leo Lesquereux, as is 

 shown by the label found with the specimen. 



Occurrence : Salina, Kansas, Dakota Sandstone (Cretaceous). Col- 

 lected and identified by Leo Lesquereux, Accession No. 4799, Car- 

 negie Museum, Pittsburgh, Pa. {No. ^y). 



Family TILIACEiE. 



Genus Grewiopsis. 



This genus was established by Marquis Saporta. To it he referred 

 leaves from the Paleocene of Sezanne, which resembled those of our 

 modern genus Grcwia. To this genus I have referred four speci- 

 mens, all differing somewhat from each other, but not sufficiently so 

 to make separate species. I have classified them as Grczi'iopsis 

 flabcllata (Lesq.) Knowlton.
