Length about 19 cm. Breadth 21 cm. These leaves are very 

 common in the pits of the Cliffwood Brick Company, occurring 

 both in the clays and in the lignites. With them are found abund- 

 ant remains of the fruit (" button-balls "). This species will be 

 more fully described and figured in the Report of the State Geolo- 

 gist of New Jersey for 1905. 



Colutea obovata sp. nov. Plate 8, figures 5, 6. 



Obovate, almost orbicular in general outline, inequilateral, 

 with rounded lobes and a rather deep and broadly rounded sinus. 

 2.5 cm. long and about the same breadth, the* broadest part being 

 toward the apex, the lower part of the blade being wedge-shaped 

 with curved margins. Midrib curved, rather stout ; secondaries 

 four or five on each side, sub-opposite, thin, ascending, campto- 

 drome, leaving the midrib at an angle of about 45 °. Tertiary 

 venation very fine, but distinctly shown. 



Type specimens consist of one perfect leaf and its somewhat 

 broken counterpart from Grove Point, Maryland. 



I was at first disposed to refer this handsome little leaf to 

 Colutea primonlialis Heer, which is so widely distributed in the 

 American Mid-Cretaceous, but careful comparison renders such 

 reference impossible. While the Grove Point leaf is somewhat of 

 the same proportions as the leaf from the Dakota Group which 

 Lesquereux refers to C. primordialis, still it is broader and more 

 refuse and has fewer secondaries. In fact a comparison of Les- 

 quereux's leaves with the type figures renders it doubtful if the 

 Dakota Group leaves are identical with the other leaves that have 

 been referred to this species by Heer, Newberry and Hollick. 

 Comparing our leaf with Heer's type figures we note that the latter 

 are larger, proportionally longer, narrower and with less rounded 

 lobes. The Raritan leaves of Newberry are entirely dissimilar in 

 outline and venation and are very angular looking. Rollick's leaf 

 from the Long Island Cretaceous is rather different from New- 

 berry's leaves, but is still less retuse and spreading than our Mary- 

 land leaf. Among the other Cretaceous species of Colutea, C 

 Langea)ia Heer is long and narrow, C coronilloides Heer is nar- 

 row and has a pointed apex, C. protogaea Heer from Patoot shows 

 two types of form, his //. 61. f. ic is broadest across the middle 

 of the blade and has a restricted sinus, while his pi. 62. f. ie has
