of Greenland, but our specimen is more open in its habit than 

 are these. So far as I am aware no one of these species has 

 yet been found in the New Jersey clays. The specimen 

 figured was collected by Mr. Wm. T. Davis at Kreischerville. 



PiNUS, sp ? 



PI. I. f. 13, 19, 20, 22. 



This genus is represented by leaves scattered plentifully 

 through the clays at Kreischerville, wherever remains of vege- 

 tation are found, and by a broken fragment of a large cone and. 

 a single scale, the former from a concretion found at Arrochar, 

 the latter from ferruginous sandstone at Tottenville. Until 

 such time as better material for study is available 1 have 

 thought it best to group all these remains together, although it 

 is j^robable that the leaves and cone represent distinct species, 

 as the flora of the clay and that of the concretions and sand- 

 stone are in general distinct one from the other. 



Dammara bouealis, Heer? 

 PI. 1. f. 17. 



In Flor. Foss. Arct. VI. 54, PI. XXXYII. f.5. Prof. Heer 

 describes and figures organisms under this name similar to the 

 one here shown. In the same volvime, PI. XLV. f. 4-11, organ- 

 isms referred to Eucalyptus Geinilzi are depicted. So far as the 

 figures are concerned they all seem to be very closely allied. Our 

 specimen is too poor for definite comparison, but the fact that 

 .thus far the abundant presence of undoubted coniferous trees in 

 Cretaceous times, particularly in the claj's of Staten Island and. 

 New Jersey is proven, while the presence of the genus Eucalyptus 

 is highly problematic, has decided me in placing our specimen 

 under Dammara, but whether or not this latter is the genus to 

 which these organisms will ultimately be referred need not here 

 be discussed. 



Locality : Tottenville, in a concretion. 



[In this connection the presence of amber in greater or less abundance 

 might be mentioned, but this could be derived from either Conifers or 

 Eucalypts, so that its occurrence is of secondary interest only.] 



PopuLus? APicuLATA, Newb. in mss. '? 



PI. III. f. 2. 



This species, represented by the upper part of a leaf only, 

 appears to be identical with that described and figured under 

 the above name by Prof. Newberry, from Woodbridge, N. J.,
