larger leaves of Hymenaca. They are described as being pin- 

 nate, but whether this character is based upon specimens seen or 

 merely upon the fact that the two figured specimens each show 

 two leaves similarly oriented, as if they had once formed part of 

 a pinnate leaf, cannot be determined. 



Prof. Newberry failed to record the exact locality for the 

 Raritan plant and it is not contained in any recent collections. 

 Occurrence. — Locality unknown.

Description. — Leaves ovate-falcate in outline, markedly un- 

 symmetrical, 6 cm. to 7.5 cm. in length by 2.4 cm. to 2.8 cm in 

 greatest breadth, which is below the middle of the leaf. Margins 

 entire. Apex acute. Base cuneate. Petiole short and stout. 

 Midrib stout and curved. Secondaries fine, about 9 pairs, often 

 obsolete, diverging from the midrib at an acute angle. 



This species was described from Mianhassett Neck, Long 

 Island, a locality which should probably be included within the 

 Raritan formation. The species is scarcely distinguishable from 

 Phaseolites elegans described by the same author from Brook- 

 lyn, and both are very close to the Dakota Group Phaseolites 

 forimis Lesq., in fact, it is scarcely conceivable that these ex- 

 tremely limited variations are not all of a single species. How- 

 ever, they should be allowed to stand until more abundant and 

 complete material is at hand for comparison. Another compar- 

 ison which is suggested is with Hymenaea' dakotana Lesq.
