query after Newberry's figures of cones and seeds in the above 

 citation. Pinus seems to be confined to the upper part of the 

 Raritan, although leaves, cones, and seeds are common in much 

 older deposits elsewhere, going back as far as the Jurassic* Leaves 

 are recorded from the Kome, Kootanie, Trinity, and Lakota forma- 

 tions ; the Albian of Europe is remarkable for the large number of 

 Piniis-\\k^ cones which it contains and Heer has recorded five

Smilax raritanensis sp. nov. 



Paliiinis ovalis Newb. Fl. Amboy Clays 107. //. 2j, /. 8, g 

 1896. Not Dawson, 1886. 



L 



Leaves of small size, ovate-elliptical, with entire margins, 

 obtusely pointed apex and slightly cuneate base, 3.5-4 cm. long 

 by 1.5-2 cm. wide. Primaries three, of medium size, diverging 

 at acute angles from the extreme base, the laterals regularly 

 curving upward and joining the midvein at the summit. Sec- 

 ondaries not visible except one or two transverse internal ones, 

 and a few curved camptodrome external ones. 



This species was identified by Professor Newberry with Paliurus 

 ovalis Dawson,* which it somewhat resembles, and this latter spe- 

 cies has been reported by Lesquereux f from the Dakota group 

 and by Hollick :|; from Marthas Vineyard. These occurrences 

 may represent Dawson's species but the Raritan leaves are obvi- 

 ously different, being relatively shorter and broader and of an 

 altogether different aspect 



Professor Newberry remarks of the difficulty of correlating 

 these and other fossil species with the modern species of Paliurus, 

 which usually has serrate or crenate leaves, and, while no new 

 material has been obtained, it seems desirable to place these leaves 

 in the genus Smilax^ which contains many very similar modern 

 leaves. Lesquereux describes two species of Smilax from the 

 Dakota group, both of which are much larger-leaved and differ 

 in other respects from the Raritan species.
