Omphalophloios cyclostigma Lx. sp. 



(Page 218.) 



. 1. Portion of flattened and apparently forked trunk. The mold of the compressed branch has, 

 been removed from the upper left, leaving the impression of the back side of the branch. 

 The back side of the cast, or branch itself, is shown in Fig. 2. On the right and in the 

 lower part of Fig. 1 the outlines of the bolsters are discerned, -while the more or less flat- 

 tened and deformed bosses are seen throughout. In the left center the inner small oral 

 bosses, including the shallow oval pits, are visible. The prominent, transverse, broken 

 surface, taugent or slightly coniiivent with the lower end of the oval boss, is construed as 

 representative of the leaf Cicatrix. U. S. Nat. Mus., .5636. 



la. Enlarged details of bolsters on the left of the same specimen, showing the oval boss with 

 central oval depression containing small mammilla. The transverse line of fracture, 

 supposed to represent the leaf scar, is not so well shown. x2. 

 2. Back side of portion of branch removed from the left of the trnnk shown in Fig. 1. The 

 opposite side of this fragment is shown in PI. LXVIII, Fig. 1. U. S. Nat. Mus., 6029.
