nearer the inner margin. It is also much like that of some species of 
Hymenzea, and it is quite possible that future discoveries will show that it 
should be referred to that genus. One species of Hymenzea (1. primigenia 
Sap.) has been found in the Upper Cretaceous rocks of Europe and is there 
associated with Aralias and Hederas, as are our Bauhinias from the Amboy 
Clays, so that it is probable the genus was represented in the forests of New 
Jersey during the Cretaceous age.

Casaupinta Cooxrana Hollick n. sp. 
Pl. XLII, figs. 49, 50. 
Leaves orbicular in outline, entire, 12" or 14"" long by 5™™" broad; 
midrib slender, secondaries few, forming a large angle with the midrib 
and anastomosing in wide loops. 
I have not been able to determine satisfactorily the affinities of these 
small, delicate leaves, and have placed them with some hesitation in the 
above genus. They appear to be leaflets belonging to some compound 
leaf, such as we find in many of the Leguminose. 
The specific name is given in honor of the late Prof. George H. 
Cook, State geologist of New Jersey. 
No indication of the exact locality where they were found or any 
speculations as to their probable botanical relations were left by Dr. 
Newberry.—A. H. 
Genus Fonratnea Newberry gen. nov. 
Shrubby or arborescent plants with opposite or alternate leaves, below 
unsymmetrically lanceolate, above forming one or two pairs which are 
united in a common petiole that is unsymmetrically winged by the decur- 
rent blade of each leaf. Apparently related to Hymenzea, to the extinct 
genus Sapindopsis described by Fontaine from the Potomac group of 
Virginia, and perhaps to Aralia elegans Vel. (Fl. der Bohm. Kreidef., Part
