species of Frenelites. When Heer discovered it in the Green- 

 land material, where it has been collected from both the Atane 

 and the Patoot beds, he transferred it to the present genus. It 

 has subsequently been reported from the Cenomanian of Bohemia 

 and Moravia, from the Magothy formation at numerous locali- 

 ties and from the southern New England islands. It has also 

 been reported from the Tuscaloosa formation of Alabama, where 

 it is abundant at a number of localities. Heer made Glyptos^ 

 trobus gracillimis Lesq., of the Dakota Group, a synonym of this 

 species, and he has been followed by many subsecjuent authors. 

 As this relation is not definitely established I have not included 

 Lesquereux's form in the foregoing synonomy, although I think 

 they may eventually prove to^ be identical. 



Widdringtonites Reickii is closely allied, if not identical, with 

 ai commi-on conifer of the Patapsco fonnation of Maryland and 

 Virginia, which is toi be described shortly as Widdringtonites 

 ramosus, being based upon Taxodinm ranwstun and various 

 other species of Professor Fontaine's Flora of the Potomac 

 Group. Staminate cones of the former are well shown in the 

 Raritan specimen figured by Newberry on pi. 8, fig. 3 (loc. cit.), 

 and similar specimens are common in the Bohemian material.
