ft. Balien Newton—FomU from Singapore, 
ascertaining the exact length of the fossil, although it is probable 
that it was a much shorter form, enoh ns hus been figured by 
Dr. Tube from Korea and compared with P. pahheUns of Heer from 
Spitsbergen (Kongl, Svennk. Vetensk.-Akad. Hand!, [Stockholm], 
1876, vol, xlv. No. 6, p. 38, pi. ix, figs. 10-14). A slight resem¬ 
blance can also be traced to a pinna recently figured by Mr, Seward 
from the Stones field Slate as P. St(tnr*fietilen*ia (Catalogue Mssor.oio 
Plante British MuBeimu Limic and Oolitic Floras of England. 1904* 
pi, iii, fig. 4, p. 123), in which a basal notch has been likewise. 
observed. 
Remains of this plant are frequently found m a poor state nf 
preservation, and only detached pinnae as n rule an* obtained, these 
being sometimes damaged at their terminations like the Singapore 
specimens. The species is a very variable one, the pinnse differing 
considerably in dimenrirms and the number of parallel venatione 
never being quite the same. Its geographical distribution is ex^ 
tensive. Originally described from the Yorkshire Oolites, it has 
since been recorded from European countries, Spitzbergen, Siberia, 
Persia, India (Upper Good wans Bede), China, Japan, and Korea. 
For an exhaustive synonymy of the species Mr. Seward's British 
Museum Catalogue should he consulted.

An isolated seed, buried in the matrix, of apparently a Cycadean 
character has been pro vision ally referred to the genus Carpolithr*, 
It is of rather oblong contour with nearly parallel sides, and bearing 
a longitudinal rounded ridge on the right margin, which nmy 
represent a fractured edge of the outer cuticle of the seed. The 
central oval and convex body, which is possibly the nuked se* d itself* 
is minutely and concentrieally striated, especially on the sides. 
In connection with the remains of PodoutmUcn it is interesting to 
find a seed of this character in assewiation, as the assemblage is 
suggestive of a Lower Oolite flora, such as characterise the rocks of 
the Yorkshire pcast, Btonesfield, and the more distant Jurassic 
regions.
