“ Indusial Limestone ” and to other strata of the Auvergne, Central 
France. From these strata M. Oustalet had described some 49 species, 
30 of which were referable to the order Diptera. 
Reference was then made to the formations of Aix, in Provence, 
belonging to the Upper Eocene period, from which more fossil insects 
had been obtained than from any other deposits except (Eningen. 
One noticeable fact about these strata was that out of the nine 
Butterflies detected in the European Tertiaries, 5 of them had been 
found here. 
The marls and limestones of Monte Bolca belonging to the Middle 
Eocene period were next referred to ; seven species of insects have 
been described from them by Signor Massai ongo. 
The American strata of the Tertiary period in which fossil insects 
had been discovered were then noticed. It appeared from a paper 
of Mr. Scudder’s that Mr. Richardson had discovered about 40 
species of insects in these strata ; besides these, about 31 species of 
Coleoptera have been described by Mr. S. H. Scudder of Boston, 
Ü.S.A. 
In conclusion, fossil resin, or amber, from the Baltic, was de- 
scribed, and a list of the genera of the various Orders of insects 
discovered therein was given, and allusion was made to the various 
writers who had treated of amber and its organic remains.

ATEW localities of Fusulina-rock in this district are — 1. The 
JLi Leptlin ravine, near Fauerburg; in the Carboniferous area of 
black and grey limestones and calcareous breccias. 2. Assling ; 
white doloraitic limestones. 3. Neumarkt ; dark-red calcareous 
breccias. 4 . The Gerauth Valley, near Neumarkt ; black lime- 
stones. 5 . The same locality ; white and light-grey limestones. 
6. Brown sandy marls. 
The black limestones of the first of these localities are particularly 
rieh in large spherical forms, some of them agreeing with Fusulina 
princeps, Ehrenberg, sp. Other deposits contain a series of forms 
approaching externally the type of F. cylindrica or of F. ventricosa. 
The facts at present known conceruing the Fusulina-beds in the 
Southern Alps 1 lead to the following conclusions : — 
1. The West to East extension of these beds in the Southern Alps 
is probably very considerable. 
2. These strata differ much in petrographical type ; they repre- 
sent, however, a definite facies among the Carboniferous group, in 
some way analogous to that of the Alveolina-beds of the Istrio- 
Dalmatic Lower Miocenes. 
3. These Fusulina-rocks appear at various horizons both above 
and below the Upper Carboniferous series. They constitute, how-
