Description. "L. ramulis gracilibus, oppositis, compressis, foliis 

 quadrifariam, facialibus rhombeis, minutis, dorso argute carinatis."- 

 Heer, 1882. 



This species was described originally from the Atane beds of Greenland 

 as a species of Libocedrus. When Professor Newberry came to study the 

 abundant remains from the Upper Earitan he changed the generic ref- 

 erence to Thuja on what appears to be good evidence. Similar remains 

 have been identified by Knowlton from the Judith River beds of Montana, 

 and the writer has noted identical remains in considerable abundance in 

 the Magothy formation of Delaware and Maryland. 



The twigs are strap-shaped with nearly parallel sides 2 mm. or slightly 

 less in width and with four rows of short appressed leaves. 



Occurrence. MAGOTHY FORMATION. Deep Cut, Delaware; Grove 

 Point, Cecil County, Maryland.
