deposited, and each successive layer could be detected by the 
concentric rings. Mr Werserep then exhibited sections of 
Limestone containing foraminifera and other organisms. 
At the close of the paper there was a very interesting 
discussion, in which Professor Harker, Mr Wrrcnerz, and 
others took part, and much admiration was expressed at the 
beauty of the microscopic sections, so well shown by the oxyhy- 
drogen light, supplied by the kindness of Mr G. Emprey, F.C.S. 
THE SECOND WINTER MEETING 
of the Club was held in the Lecture Theatre of the 
SCIENCE SCHOOL IN GLOUCESTER, 
on the afternoon of Tuesday 16th of February. Mr HE. 
Wircuett exhibited a fine specimen of Pachycormus, recently 
found by him in the fish-bed of the Upper Lias at Stroud. 
He then proceeded to read a paper on “The genus Nerinea, 
and its stratigraphical distribution in the Cotteswolds.” 
Diagrams, showing the internal structure of several of the 
species, and some fine specimens of the fossils, were exhibited. 
Mr Wirtcuett said that the paper was to be understood as 
referring to the fossil shell known as Nerinea, and not to the 
animal, which has been long extinct. He gave a description 
of the shell, and of the internal structure of several species. 
The genus is stated by Woopwarp to have first appeared in the 
period of the Inferior Oolite, and to have become extinct in 
that of the Chalk. The number of species was estimated at 
150. The advent of the genus in the Inferior Oolite was 
marked by four or five species, all of which were found in the 
Pea Grit of the Cotteswolds, and are abundant. Mr Wircnett 
enumerated the several beds in the Inferior and Great Oolite 
in which the species are found, and said that the number at 
present ascertained to exist in these beds was at least 28. Of 
these Lycrrr had only mentioned 10 in his works. He pointed 
out that these might, from their internal form, be divided into 
five groups, but that one species, N. Guisei, differed from all 
the others, and from the whole of the species figured by
