IXCERT.E SEDIS 225 



Description. — Indefinite fioral or fruit-remains of variable size. 

 2.5 cm. to 4 cm. long, by 2.5 cm. to 3 cm. in diameter, cylindrical, 

 apparently ctipshaped, and with a simple margin, which may be 

 slightly expanded or contracted; narrowing below to a compara- 

 tively slender peduncle. Base and peduncle apparently covered 

 with scales or small bracts, although the preservation is such that 

 this is rather inferential. 



'Prof. Newberry sees in these objects a not altogether obvious 

 resemblance to VVillianisonia cretacea Heer. They may be re- 

 lated to the Cycadales, but this supposition is far from positive, 

 and they are retained in the genus tO' which Prof. Newberry 

 referred them, rather than make a change based upon the slender 

 evidence available. They are said to be common in the Raritan, 

 several specimens having been figured by their describer, who 

 failed, however, to record the exact locality, and no new material 

 is contained in the more recent Raritan collections. 



Occurrence. — Locality unknown.

Description. — Fructifications consisting of a long and stout 

 peduncle preserved for a length of 2 cm. to 3 cm. and about 7 

 cm, in diameter, expanding distally into a discoid conical recep- 

 tacle, the edg-e of which is surmlounted by 10 to 20 lanceo- 

 late bracts 1.5 cm. to 3.5 cm. in length and 2 mm. to 10 mm. in 

 diameter, the whole of a very durable consistency. 



These objects are present in considerable abundance in the Rar- 

 itan clays, and Prof. Newberry figures a number of specimens, 

 althousfh he nesflects to mention the localities from which thev
