leaves is not so distinct. . These features may be due to the accidents of preservation, 
and do not call for the separation of the Pennsylvania plant as a variety. The 
leaves of this form are strikingly like those of Cheirolepis gracilis Feistm. of the 
Rajmahal flora. 
The following is Mr. Wanner’s record: 
Fig. 3, Pl. XX XI, represents a very symmetrical branch in an excellent state of pres- 
ervation. Both twigs and leaves are crowded closely together. Fig. 4 presents 
another specimen, containing near the extremity of one of its lateral branches the 
impression made by some kind of afruit. Beyond the general outline and the unmis- 
takable imprint made by the stem, by which it is attached to the twig, the fruit con- 
tains no definite markings to give it character. In another specimen not illustrated 
the leaves are somewhat larger. Fig. 5 shows the venation in a magnified leaf. 
Palissya diffusa is common at the York Haven locality and may be represented at 
the Little Conewago Creek, but the few fragmentary specimens from the latter place 
eannot be positively identified. 
Locality.—N. C. R. R. cut, south of York Haven. 
Genus BRACHYPHYLLUM Brongniart. 
BRACHYPHYLLUM YORKENSE Fontaine n. sp. 
Pl. XXXI, Figs. 6-9. 
Mr. Wanner identified this with Brachyphyllum crassicaule Font., of 
the Potomac flora. Professor Fontaine does not accept this, and says: 
This is not Brachyphyllum crassicaule, but a’ new and smaller species, which may 
appropriately bear the name B. yorkense. 
There are in Mr. Wanner’s collection several imprints of a small Brachyphyllum 
which resembles Saporta’s B. Papareli, a plant of the Rhetic and Infralias of France. 
It is, however, I think, a new species. Mr. Wanner’s figure shows the most com- 
plete specimen. The ‘ultimate twigs on this are very slender. The full length of 
none of them is shown. They are only 2mm. wide. The leaves seem to be thinner 
in texture than those of the Jurassic Brachyphylla. They are rotundate-rhombic in 
form, with the longer diameter transverse to the axis of the twig. Fig. 8 shows the 
shape of the best-preserved forms, the enlargement being 3 diameters. They are 
subspirally arranged, somewhat after the fashion of those of Paleeocyparis (Echinostro- 
bus) of the Oolite. 
Mr. Wanner says of it: : 
Fig. 6, Pl. XX XI, presents a branch containing closely placed lateral twigs. Other 
specimens from the same locality vary considerably in the number of branches, 
usually having fewer than are contained in the illustration. No terminal branches 
were identified to a certainty, though several blunt ends may represent extremities, 
and if such is the case the width of the branch remains the same throughout its 
extent. The leaves are thick and closely appressed, with beaks and a scarcely 
perceptible keel, as illustrated in Fig. 7, a magnified leaf. 
Locality.—Little Conewago Creek, exploitation pit. 
With regard to the small specimen, Fig. 9, Professor Fontaine 
remarks: ; 
I did not see this small fragment. It is probably a portion of a twig of Brachy- 
phyllum yorkense, above described.
