fortunately docs not permit a microscopical examination. Nathorst 

 (1897) has described similar coniferous remains as Pinites fPityo- 

 phijllnmj Staratschini (Heer). 



Occurrence: Atanekerdluk, Greenland; Kap Staratschin, Spitz- 



bcrgen. 



Geological age: Middle Cretaceous — Upper Jurassic. 



Sciadopitytes Lagerheimii X. Joh. 



Recently described by Johansson (1920). In the preparations of 

 this species I have also foiind the non-stomatiferous groove to be 

 very distinct. The subsidiaiy cells are papillate. Their number 

 is 6 (2 + 4). 



Occurrence; Andö, Norway. 



Geological age: Upper Jurassic. 



Sciadopitytes persiilcata N. Joh. 



Recently described by Johansson (1920). In the preparations of 

 this species I have also found the non-stomatiferous groove of the 

 upper (?) side of the double needle. The 6 (2 + 4) subsidiary cells 

 are papillate. 



Occurrence: Andö, Norway. 



Geological age: Upper Jurassic. 



Sciadopitytes scotica, sp. nov. 



I have found a specimcn with 10 or 12 double needles, crowded 

 together in such a manner as to make their verticillate arrange- 

 ment on the main axis very probable (ef. Sciadopitys verticillata). 

 The double needles séem to have been ca 90 mm long and 1,5—2 

 mm broad. On the under (?) side therc is a median stomatiferous 

 but non-papillate groove, whose margins lack papillae and cuticular 

 lists. The stomata occur in longitudinal rows. The number of 

 subsidiary cells is 4—7 (2 polar and 2—5 lateral ones). 



Occurrence: Helmsdale, Scottland. 



Geological age: Upper Jurassic.
