Description. — " Foliolis elougato-lineali-lanceolatis, centim. 6 cireiter 

 longis, infra medium millim. 5 latis, basin versus margine inferiore 

 subitius angustatis quam superiore, decurrentibus, sat approximitis et 

 erecto-patentibus ." — S chimper^ 1870. 



This species has a very wide range, both geological and geographical. 

 It is common in the Jurassic of high latitudes in Russia (the type re- 

 gion), Siberia, Bornholm, and Spitzbergen. In the Lower and Upper 

 Cretaceous indistinguishable remains are rather widely distributed^. 

 These occur in the Patapsco formation of the Potomac Eiver valley, the 

 Earitan formation of New Jersey, and the Dakota Group of Kansas. 

 Whether or not they were speciiically identical with the Jurassic forms 

 cannot be proven, although they present no character aside from differ- 

 ence in geological horizon to warrant their separation. 



Occurrence. — Patapsco F5rmation. Vinegar Hill, Fort Foote, Mary- 

 land; Mt. Vernon, Virginia. 



Collection. — U. S. National Museum.
