Genus CUPRESSINOXYLON Goeppert (?)

CUPRESSINOXYLON ? BIBBINSI Knowlton 



Cupressinoxylon ? 6i&&insi Knowlton, 1896, Science, n. s., vol. iii, pp. 582- 

 584, tf. 1-4. 



Description. This species was based on sections of poorly preserved 

 lignite from the type locality of the Magothy formation at Cape Sable. 

 The wood cells are almost obliterated by crushing : the radial sections show 

 the walls to have been thick and with a single interrupted series of large 

 bordered pits ; the rays, as shown in tangential sections, are crushed, but 

 appear to have been uniseriate and of about four cells. 



The material upon which this species is founded is much too incom- 

 plete for even successful generic determination. The genus Cupressi- 

 noxylon to which it has been referred was discussed by the writer in a pre- 

 vious report 1 and need not be amplified in the present connection. 



Occurrence. MAGOTHY FORMATION. Cape Sable, Magothy Eiver,
