described by the earlier authors were all from Jur;H>ic lioii/oiis 

 but subsequently species were described from tlic ( n i.u.M mis.' 

 and it is with these that we are esi)ecially conci'rncl. 



The question of li-oiieric idciititv bctwcoii the M'\fr;ii iiHicd

 The oidy matter which is of iinnic(hatc concern is tlu- t;ict iluit 

 we have found at Kreischerviile tiie leafy branches of a Hrachy- 

 phylhim and have l)een able to determine, for the first time, by 

 means of its internal structure, the exact relationship which it 

 bears to certain living Conifera?. This species is the same so far 

 as external characters are concerned, as that described by New- 

 berry from the Amboy clays of New Jersey (li. marrocdrpum 

 Xewb., he. (-//.), and it has also been found at \orthj)ort. 

 Long Island, and at Cliffwood, N. J. A reproduction of New- 

 berry's fig. 1 (Inc. cif.) is shown on Plate 1, Fig. 15, and the North- 

 port specimens on the same plate, Figs. 16, 17. These are all 

 natural size. 



Plate 3, Figs. 1 a, b, c, shows three fragments of branches from 

 Kreischerviile, magnified about fi times, and Fig. 2, on the same 

 {)late, shows one magnified about 10 times. 



Plate 3, Fig. 3, shows a piece of another branch magnified about 

 the same as the latter, and illustrates particularly well the longi- 

 tinhnal converging striit^ characteristic of the leaves of Brachy- 



Plate 3, Fig. 4, re{)rcsciits a transverse s(>cti()n through a rela- 

 tively old branch, magnified bv S. ni w hich the woody cylinder is 

 well developed. The pith has hugely colhipsed. aUhough it con- 

 sists in large part of sclerotic cells. 



Plate 3, Fig. 5, shows a transverse section of n yonni:- branch, 

 magnified by ]5. Four leaves may be seen on the margins of the 

 figure, and of these, those on the inroad uppei- and lower surfa. es 

 of the branch overlap those on the mar-ins. as thcv are cnt thnaigh
