underwood ; and tke Irish ‘ Film-fern ’ ( Hymenophyllum unilaterale) 
flourished in many favoured spots until quite recently, wken the 
modern Eccles Hotel has retained tourists too long in the district, 
who have ruthlessly carried off, as reminiscences of a pleasant holiday, 
this whicli was one of the most attractive features to the botanist.” 
After mentioning that in the two lower fresk-water series there 
are no animal remains but what have been blown in, among tkem 
insect wings and the earliest known English feather, the lecturer 
went on to speak of the pkysical conditions under which he supposes 
the beds were formed. He said that he regarded a river flowing 
from west to east as having deposited all these beds in a valley 
of from seven to ten miles, which it liad made, and showed a 
picture of the restoration of what he supposed the view was like. 
The foreground of the picture was made up of plants from Mrs. J. 
E. Gardner’s couservatory, being the nearest known living repre- 
sentatives of the fossil plants. 
A block 'opened before the audience proved fortunately a good 
one and crowded with leaves. Some experiments were made during 
the lecture showing that there is in the decomposed granite enough 
iron to account for the colours of the clay. 
II. — Note sur un nouveau genre d’Entromostrace fossile proye- 
NANT DU TERRAIN CARBOXIFERE DES ENVIRONS DE SäINT-EtIENXE 
( Palceocypris Edicardsii), par M. Charles Brongniart. 
ANY traces of the former existence of Entomostraca are to be 
found in the different geological formations, their carapaces 
being often admirably preserved and exliibiting all their exterual 
markings, wliilst every vestige of the animals themselves has been 
entirely removed. Much uncertainty, therefore, exists conceming 
the exact zoological affinities’of these fossils, and Palmontologists 
have been obliged to base their classifications on tlie form and ex- 
ternal ornamentation of the carapace. M. Ch. Brongniart has been 
enabled, however, by a rare good chance, to examine and describe 
the remains of some Ostracods from the Coal-measures of Saint- 
Etienne, in which not only the carapace, but also the more delicate 
appendages, such as the antennte with their kairs, the feet, etc., 
have been preserved. These Entomostraca, which were found im- 
bedded in the silex filling the interior of a Cardiocarpas, are closely 
allied to the recent genus Cypris, but at the same time, as tliey differ 
in several essential characteristics from that genus, the author pro- 
poses to designate them Palceocypris Edicardsii, after Prof. Milne- 
Edwards, and gives the following details of their structure : — 
Palceocypris Edicardsii is only half a millimetre (-Aiin. nearly) 
in length ; the body, as in Cypris, is enclosed in a bivalve, oval test, 
laterally compressed. The valves are narrower in front than behind, 
and their surface is covered with granulations, whilst numerous very 
short and fine hairs are seen springing from the dorsal margin. 
The body, properly so called, does not occupy the wliole of the 
interior of the carapace ; in front it approaches the dorsal edge, and 
at the bottom it almost touches the (ventral) margin of the valves.
