From Cape Lisbourne, Alaska. Collected by Mr. Henry D. Woolfe. 

 Age probably Neocomian. 



Ginkgo multinervis Heer. Plate xvi, fig. 6. (Heer, Fl. Arct., vi, (2) p. 40, PI. viii> 

 figs. 2b, 3, 4; PI. ix, f. 36.) 



Heer describes the species as leaves palmate, deeply lobate, narrowed 

 toward the base, cuneate truncate at apex ; nerves thin, numerous, very 

 close. The specimens from Alaska agree entirely with the description 

 and figures of Heer, I. c, except that he says of the lobes, that they are 

 truncate at apex. They are truncate by erosion or breakage, but really 

 obtuse as Heer has figured them, PL ix, figs. 3, G. The Alaska speci- 

 men is only better preserved. 



One specimen ; Museum number, 2482. 



Baiera palmata Heer. Plate xvi, figs. 4, 5. (Heer iu Fl. Ost. Siberia, p. 115, PL 

 xxviu, figs. 2-a-d.) 



The specimens from Alaska represent only the lower part of the leaves, 

 which are entire to the middle or above, and there digitate, laciniate, 

 the division of the laciuiaj being merely seen in a sinus at a distance 

 of 9 cm from the base. Iu Heer's specimens it is mostly the upper part 

 or the lacinise which are preserved. A fragment of one of the laciniae is 

 9 cm long, l£ cm broad, broken at both ends. The characters are as de- 

 scribed by Heer. 



Five specimens ; Museum number, 2437. 



Podozamites latipennis Heer. Plate xvi, figs. 2, 3. 



The species is represented in many figures by Heer (FL Arct, vi, (2) 

 PL xiv, figs. 1-9). It is described (p. 42) as leaves (pinnae) large; leaf- 

 lets open, alternate, a little distant, long-lanceolate, 11 to lG ram broad, 

 narrowed to the base, gradually narrowed to the apex; nerves thin, 

 close parallel.
