ABBER : FOSSIL FLORA OF SOUTH YORKSHIRE COALFIELD. 143 
From the Old Albany clay pit, at some little distance below 
the Kilburn Coal, specimens of Calamites Suckowi Brongn. were 
obtained. Calamites cisti Brongn. and C. varians Sternb., 
P. miltoni (Artis), Rhabdocarpus elongatus Kidst., are known from 
the Lower Coal Measures of other coalfields, though Pecopteris 
miltoni is very rare on this horizon. On the other hand, Neurop- 
teris osmundce (Artis) and N. obliqua Brongn. have not hitherto 
been found, so far as I am aware, below the Middle Coal Measures, 
on which horizon they also occur in Derbyshire and Nottingham- 
shire. 
NOTES ON SOME OF THE FIGURED SPECIMENS. 
A selection of typical fossils from Dr. Moysey's collection is 
figured on Plates XII. -XIX. Several of these are well known 
plants in other coalfields, and do not call for remark here. Other 
specimens, however, are rarer, or particularly well preserved, and 
in these cases the following notes may perhaps be of service, in 
addition to references to further figures of the fossils themselves.

It may be doubted if a more complete specimen of this fructiferous 
branch of a Calamite than that figured on Plate XII. has ever 
been found. The cones are, for the most part, still in continuity 
with the slender axis, which bore them. They were borne in whorls, 
of whic^ four are seen in the photograph. Four or more cones 
appear to have been attached to each node. The cones measured 
about 6 cm. in length, and they were apparently sessile. . The 
bracts are small and short. The sporophylls and sporangia caa
