Series ( })Thallophyta . 
Genus Bythotrephis , J. Hall, 1847. 
Bythotrephis divaricata, Kidston. PI. XXXVIII., Fig. 1. 
B. divaricata , Kidston, 1886, Cat. Pal. Plants, Brit. Mus. (Nat. 
Hist.), p. 243. cf. Yates, 1829, Trans. Geol. Soc. Lond., 2nd Ser. vol. 
II., PI. XXVII., Fig. 2. 
The above species appears to be related to J. Hall’s B. gracilis , as 
it marked by Kidston; but it may be distinguished from that form by the 
slender habit of its long lateral branches, which extend in the present 
instance to’ a length of 78 mm. In our specimen the side branches are, to 
some degree, flexuous, as in B. tenuis , J. Hall, but the main stem is more 
erect. The examples of B. divaricata in the British Museum collection are 
recorded from the Wenlock of Malvern in Shropshire, England. 
Occurrence. —Centennial Mine, Vale’s Adit, Walhalla (No. 532).

XXXVIII., Fig. 3. 
The present specimen has numerous, long, slender branches of about 
40 mm. in length. There are signs of secondary branches at intervals, at 
an acute angle of divergence. The numerous branches are all con¬ 
fluent close to the base, which is slightly swollen. Our fossil appears to be 
identical with Gdppert’s species, which only differs in having finer branches 
with a decided outward curvature. In Sandberger’s description it is stated 
that there are no visible branches, but this is not borne out by the figure 
there given. It occurs in the Lower Devonian in Germany.
