linAJViNiJS GoLDLiNUS, var. LATiOR, Lsqx. 



Described witli specimens from Golden. 



JuGLANS DENTicuLATA, Heer, in Eept. 1871, p. 298. 



A large form, only found in fragments. It may be a new species. 



Carbon, above coal. 



Taxoditjm dubium, Sternb. 



The same small form as the one published by Heer in Arct. Flor. I, 

 p. 89, PI. ii, Fig. 24 to 27. It is re|Dresented by a number of small but 

 distinct specimens. 



POPULTJS ATTENUATA, Al. Br. 



Found also below the coal of the same locality. 



QUERCUS ACRODON, Lsqs., Am. Jour. Sci. and Arts, 1868, p. 205. 



A good specimen of this fine species. The ovate pointed leaf, wedge- 

 form to the petiole, has the borders deeply cut into large, sharp teeth, 

 with straight, mostly simple, secondary veins, passing in an acute angle 

 to the point of the teeth. In this new specimen, the upper secondary 

 veins are slightly curved in ascending to the borders. 



CORYLUS McQuARRYi, Heer, in Eept. 1871, p. 292. 



Eepresented by fragments and in various forms. I have not seen, as 

 yet, an entireleaf of this species. 



Fagus Deucalionis, TJng. 



The same form represented in Arct. Fl. I, PI. xlvi, Fig. 4. Speci- 

 men found by Professor B. F. Meek. 



Platanus aceroides, Gopp. 



A number of specimens, all imperfect, referable to this species by the 

 larger size, the thickness of the leaves and the coarseness of nervation. 



ZiZYPHUS Meekii, Lsqx. 



Described above from specimens of the lower shale. 



ZiZYPHUS HYPERBOREUS (1) Heer, Fl. Arct. I, p. 123. 



Leaf large, broadly lanceolate, largest below the middle, rounded- 

 attenuated to the short petiole, tapering into a long linear point, irregu- 

 larly crenate ; five-nerved from the base. 



This leaf is 10 cent, long with its short or broken petiole, 5 cent, 

 wide ; the first lateral veins are as deep and thick as the medial one, 

 nearly aerodrome ; the marginal ones, thinner, ascending to above the 

 middle; the Tertiary veias, or fibrillge, are obliterated. This leaf
