" Indusial Limestone " and to other strata of the Auvergne, Central 

 France. From these strata M. Onstalet had described some 49 species, 

 30 of which were referable to the order Diptera. 



Eeference 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 Signer Massalongo. 



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, 

 U.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. 



II. — On somr Fusulina Limestones. By Dr. G. Stache.

A. From Upper Carniola. 



NEW localities of Fusi^lina-rock in this district are — 1. The 

 Leptlin ravine, near Fauerburg ; in the Carboniferous area of 

 black and grey limestones and calcareous breccias. 2. Assling ; 

 white dolomitic 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 

 inch in large spherical forms, some of them agreeing with Fmulina 

 princeps, Ehrenberg, sp. Other deposits contain a series of forms 

 approaching externally the type of F. cyUndrica or of F. ventricosa. 



The facts at present known conceniing the Fusulina-beds in tlie 

 Southern Alps^ 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 fades 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-
