PROCEBDINaS 
OF THE 
FEBRUARY, 1866, 
GENERAL MEETING. 
Thursday, Feb. 1st.— Mr. W. Sanders, F.R.S., F.G.S., President, 
in the chair. 
The Hon. Secretary announced that the following gentlemen had been 
duly elected ordinary members : — G. Gillford, F. R. Bernard, T. Usher, 
R. S. Standerwick. 
Mr. W. W. Stoddart read a note on Involutina liassica, a microscopic 
fossil, new to the Bristol district. At the Bath meeting of the British 
Association^ Mr. Brady, of Newcastle, had read a paper announcing the 
discovery of this fossil in the Lias beds at Fretherne cliff and Defford, 
and had then proposed the above name for it. Mr. Stoddart had been 
fortunate enough to meet with it at Horfield, and after stating that it 
belonged to the lowest division of animal life, Foramenifera, he gave a 
general outline of the characteristics of this group, with the classification 
proposed by Dr. Carpenter in his monograph, and illustrated his remarks 
with some photographs projected on a screen by the oxy-hydrogen micro- 
scope. In the classification now generally adopted, the whole group was di- 
vided into three subordinate groups, named, according to the character of 
the shell, Porcellanous, Hyaline or vitreous, and Arenaceous : the fossil 
described by the author belonged to the last division, in structure lying 
between Rotalina and Trochammina, and considered by Mr. Brady as 
possibly a pseudomorph of Pulvinulina. In character it was dis- 
coidal, biconvex, from l-15th to l-70th of an inch in diameter, and 
l-48th inch thick — granulated, the outer edge raised — spiral walls, with 
straight septa.
