Through the kindness of Dr. A. Geikie, Director-General of the Geological Survey of Great Britain, I have had the pleasure of examining the fossil plants collected by the Scottish Geological Survey from the Calciferous Sandstones of Eskdale and Liddesdale.

page 536 note † Mr. C. W. Peach has shown me young fronds of S. affinis in the circinate condition, exhibiting very beautifully the two forks rolled up in a crozier-like manner.

page 539 note † I differ from Mr. C. W. Peach in the identification of his Sph. affinis, and prefer calling the form which occurs on the slabs with staphylopteris Peachii, Sph. linearis. What I regard as Sph. affinis differs from S. linearis in having much smaller pinnules. It is most likely that these two ferns should form only one species, and, at the most, S. affinis be regarded as a variety of S. linearis.
