Description. Twigs of a conifer, represented in the clays by crowded 

 cylindrical branches of graceful aspect and slender forking habit. The 

 leaves are reduced almost to the vanishing point, in fact most specimens 

 fail to show any traces of leaves whatever, and it is possible that these 

 spirally-arranged scale-like leaves of Newberry's description may have 

 been founded upon deceptive material. 



These twigs are unjointed, an objection against their former reference 

 to the genus Frenelopsis. It has been suggested that they represent decor- 

 ticated specimens of Widdringtonites reichii (Ettingshausen) Heer, 

 which is so common in the Earitan and overlying Magothy formation. 

 The present species is recorded from both Delaware and Maryland. 



Hollick and Jeffrey have shown (loc. cit.) from anatomical prepara- 

 tions that the present species is not related to Frenelopsis or Widdring- 

 tonites, but constitutes a distinct genus. 



Occurrence. MAGOTHY FORMATION. Deep Cut, Delaware; Grove 

 Point, Cecil County, Maryland. 



Collection. Maryland Geological Survey.
