380 Reports and Proceedings— 
Sandstone of Perthshire, Scotland, and to a species of the genus 
Dicranophyllum of Grand’-Eury, discovered by Mr. J. L. Jack, F.G.8., 
in the Devonian of Queensland. 
In all, this paper added six or seven new types to the flora of the 
Erian period. Several of them belong to generic forms not previously 
traced further back than the Carboniferous. 
The author uses the term “ Erian’’ for that great system of for- 
mations intervening in America between the Upper Silurian and the 
Lower Carboniferous, and which, in the present uncertainty as to 
formations of this age in Great Britain, should be regarded as the type 
of the formations of the period. It is the ‘‘ Erie Division” of the 
original Survey of New York, and is spread around the shores of Lake 
Erie, and to a great distance to the southward. 
6. ‘“‘On the Terminations of some Ammonites from the Inferior 
Oolite of Dorset and Somerset.” By James Buckman, Esq., F.G.S., 
F.L.S. 
The author referred to the figures given by D’Orbigny of Jurassic 
Ammonites having the mouth-termination perfect, and proceeded to 
describe the characters presented by complete specimens obtained by 
him from the Inferior Oolite of Dorsetshire and Somersetshire. He 
enumerated 14 species, which he classified as follows, in accordance 
with the nature of the terminations:—1. Termination lanceolate, 
z.e. with a lance-shaped process on each side of the mouth (4. con- 
cavus, subradiatus, Kduardianus); 2. Ovato-lanceolate or spathulate, 
z.e. with a spathulate process on each side of the mouth (4. Braiken- 
ridgit, lingurferus, Sauzii, DMartinsii, subcostatus); 3 Delphinulate 
‘side view like that of the classic dolphin” (A. Gervilliz); 4. Semi- 
circular (4. Brongniarti, Manselii, Humphresianus); 5. Waved 
(A. Mooret, boscensis). 
7. “Farde Islands. Notes upon the Coal found at Suderoe.” 
By Arthur A. Stokes, Esq., F.G.S. 
The coal in this district is associated with shales, and these are 
interbedded with sheets of basalt and dolerite. It is worked after a 
primitive fashion by the natives. Some of the seams are more than 
half a yard thick. There are two varieties of the coal or, rather, 
lignite, containing respectively 51:7 and 68°2 per cent. of carbon. 
The author gave details of sections and other matters connected 
with the coal-bearing area, and various notes upon the geology of 
the district. 
8. ‘On some new Cretaceous Comatule.’ By P. Herbert 
Carpenter, Hsq., M.A. Communicated by Prof. P. Martin Duncan, 
MOB. ERS taG-s: 
In this paper the author described five new species of Antedon from 
British Cretaceous deposits, two of them in the possession of the Rey. 
P. Brodie, the rest in the collection of the British Museum. The 
species are: Antedon perforata and A. Lundgreni, from the Upper 
Chalk, Margate; 4. striata, from the Upper Chalk, Dover; 4. 
laticirra, from the Chalk of Wylye, Wiltshire; and 4. incurva, from 
the Upper Greensand, Blackdown. The author further gave a tabular 
key to the known English Cretaceous species of Antedon, and in 
conclusion referred to certain peculiarities in the structure of these
