fortunately does not permit a microscopical examination. NATHORST
(1897) has described similar coniferous remains as Pinites (Pityo-
phyllum) Staratschini (HEER).
Occurrence: Atanekerdluk, Greenland; Kap Staratschin, Spitz-
bergen.
Geological age: Middle Cretaceous — Upper Jurassic.
Sciadopitytes Lagerheimii N. Joh.
Recently described by JOHANSSON (1920). In the preparations of
this species I have also found the non-stomatiferous groove to be
very distinct. The subsidiary cells are papillate. Their number
is 6 (2+4).
Occurrence: Andö, Norway.
Geological age: Upper Jurassic.
Sciadopitytes persulcata 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 specimen 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 (cf. Sciadopitys verticillata).
The double needles seem to have been ca 90 mm long and 1,5—2
mm broad. On the under (?) side there 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.
