7. On the Fossil Plants of the Upper Culm Measures of Devon. 
By EH, A. NEwett Arser, Jf. A. 
The Upper Culm Measures form by far the largest portion of the Carboni- 
ferous sequence in Devon and the adjacent counties. Fossil plant remains are 
abundant in these beds, but their preservation is rarely sufficiently good to permit 
of even generic determination. A number of well-preserved specimens have, how- 
ever, recently been obtained from the one horizon in which coal or ‘culm’ occurs 
in these beds in the Bideford district. They include Calamites undulatus, Calamo- 
cladus charefornus, Alethopteris lonchitica, A. Serli, Neuropteris obliqua, 
Sigillaria tessellata, and many others. Neuropteris Schlehani and Megalopteris (F)sp. 
are also recorded from Britain for the first time. 
This flora confirms the previous conclusions with regard to the Upper Car- 
boniferous age of these beds, and indicates that the coal-bearing beds of the 
Bideford district are the equivalents of the Middle Coal Measures elsewhere in 
Britain—a higher horizon than has previously been assigned to these beds. 
8. On Derived Plant Petrifactions from Devonshire. 
By HK. A, Newent Arser, Jf.A. 
Some interesting plant petrifactions in which the structure has been to some 
extent preserved by means of a mineral agent have recently been discovered in 
the higher beds of the Upper Culm Measures (Upper Carboniferous) in Western 
Devon. Although the preservation is not sufficiently good to render this dis- 
covery of any botanical importance, the manner in which the fossils occur is 
interesting from a geological point of view. The plant remains consist of small 
rolled fragments of stems, of an inch or less in length, arranged without order in a 
fine-grained sandstone. They are in all probability derived from some pre- 
existing beds, and are not contemporaneous with the sandstone in which they are 
found. Such derived plant remains are very rare, if not unknown, from the 
Paleozoic rocks.

10. On Lootprints of Small Fossil Reptiles from the Upper Karroo Rocks 
of Cape Colony. By Professor H. G. Sunny, /.R.S. 
The author recognised a slab of fine-grained sandstone in the Paleontological 
collection of the University of Munich, which contains impressions of the feet of 
three kinds of reptiles and also preserves casts of small phalangeal bones terminated 
by compressed claws. This was collected about 1880, near Middleburg, together 
with a small Theriodont skull allied to Hyorhynchus. 
The surface of the slab appears to show faint ripple marks, an inch or two 
apart. The larger footprints cross these markings at an angle of about 45°. The 
prints are in relief; indicate a pentadactylate animal, with the fore and hind feet of 
nearly equal size. The digits are widely spread, stout, and terminate bluntly, 
without any indication of claws. The palmar surface is most convex towards the 
first digit, and there is a convexity under each metacarpal and metatarsal bone. 
The point is less deep towards the outer side, so that the outermost digit appears 
to be exceptionally slender. The width of the hand is about one inch, and the 
length did not exceed one inch and a half; at the carpal border the width is 
eight-tenths of an inch. There appear to be four bones in the distal-tarsal row. 
The hinder tarsal border is formed of three convex curves, which appear to 
indicate the three bones in the proximal tarsal row. There is a slight impression 
of the tail, showing a fine granular skin ornament, arranged quincuncially. In 
size the digits are not unlike those of Mesosaurus, though in the shorter
