being in our leaves on a broader angle of divergence than that of the 

 upper veins. In Heer's Fig. 1, loc. cit, the lowest veins are more in- 

 clined. But in another, Fig. oa, of the same plate, tlie secondary veins 

 are still more open than in our leaves, though all parallel. All our 

 specimens have the lower part of the leaf destroyed; the comparison, 

 therefore, is not conclusive, though these leaves belong evidently to a 

 Magnolia of a same type. 



SapijsDus caudatus, Lsqs. 



Described above with specimens from Golden. The leaves here are 

 slightly shorter, narrowly taper-pointed or with a shorter j^oint than 

 those of Golden, indicating thus still more the relation of this species 

 with Sa^indus duMus, Heer. 



Aleurttes Eocenica, S]). nov. 



Leaves membranaceous, thickish, oval, pointed, wedge-shaped to a 

 long petiole, minutely and distantly glaudulosely denticulate, penni- 

 nerve; secondary veins alternate parallel; nervation complex. 



Many fragments with one leaf preserved in its whole. It is 6 J cent, 

 long, 2^ cent, broad in the middle, its widest part, with a petiole of the 

 same length, 2J cent. long. The nervation is com^^lex and mixed. The 

 secondary veins, emerging under an angle of 40°, either curve at a dis- 

 tance or near the borders in angular bows, their branches passing 

 straight from the angles to the borders, where they enter a very small 

 round glandular point ; or these secondary veins themselves pass up 

 after anastomosing on both sides, and enter, too, a small gland of the 

 borders. The same nervation and same form, consistance, &c., of leaves 

 are marked in Aleurites trilohaj Gr., of Cuba. I couvsider these leaves 

 referable to this genus. 



Paliurus zizyphoides, sp. nov. 



Leaves subcoriaceous, entire, oval, or obovate obtuse, curving down 

 ward to a thick, short petiole, live-nerved, the two lowest lateral veins 

 from the borders of the petiole, the other from the medial vein a little 

 higher; camptodrome. 



The leaves vary in size, the largest one, nearly round, being 5 eent. 

 wide. They are properly three-nerved from the base, the lowest veins 

 being rather marginal ones, much shorter than those of the first pair. 

 These ascend in acute angle to the borders, which they follow, branching 

 outside ; the medial nerve is pinnately divided from the middle upward. 

 The same species, represented by a smaller leaf, has been found at Erie. 



Eham:\'U3 eectineryis, Heer. 



Represented by two good specimens. 



Ehajijtus Dechenii, Web., Pal., YlII, p. 90, PI. vi, Fig. 2, 



A broken specimen only, representing, however, this species. It 

 merely differs by the more deeply-marked nervilles. The secondary 

 veins are not as strong and deeply marked as in the former species. A 

 broken specimen from Golden by Professor B. F. Meek is also referable 

 to this.
