(1) 510 plants are recorded from various localities in the coalfield, fossils having been collected from several new localities.

(2) Fossil-plants are noted for the first time from the upper beds of the “Millstone Grit” of this district.

(3) Two new species of Sigillaria are described and figured.

(4) The known flora of the coalfield has been increased. Of the plants recorded—

6 species have not been recorded previously from Britain.

62 species have not been recorded previously from the coalfield, and

290 species have not been recorded previously from various localities in the coalfield.

Many of the species which have been previously recorded are here referred for the first time to definite horizons.

(5) The known vertical distribution of 38 species is extended to the Staffordian Series.

Recent papers and discussions have called attention to the fauna of the Yoredale facies of the Lower Carboniferous. These beds are well exposed in the valleys of Wensleydale and Swaledale in North West Yorkshire and they are there, perhaps, the most fossiliferous. As this is the type district for the Yoredale series, a brief statement of the more important faunal horizons would not be out of place.

In the course of detailed mapping over this area, with a view to throwing some light on the complicated geological structure of the district, the discovery of various graptolites, largely from new localities, both confirms and extends the previous records of Dr. C. A. Matley and Mr. W. Keeping.
