16 GEOLOGICAJ- MEMOIRS. 



Terebratula diphya, V. Buck. Ammonites viator, IfOrh. 



triquetra, Park. Zignoanus, D'Orb. 



bicanaliculata, Schlot. anceps, Rein. 



resupinata, Pusch. athleta, Phil. 



Aptychus latus, Milnst. Hommairei, D'Orb. 



lamellosus, Voltz. Spatangus carinatus, Gold/. 



With this group (which, together with the yellow bed with Ter. insig- 

 nis, appears to me to represent collectively D'Orbigny's Callovien and 

 Oxfordien) terminates the series of the Jurassic rocks of the whole of 

 the Venetian, Lombard, and South Tyrol Alps. 



From this short notice it is easily seen, that the Jurassic plant-beds 

 of Rotzo in the Vicentin and of Pernigotti in the Veronese are above 

 the Lower Oohte and just at the place which corresponds to that of 

 the Great Oolite, or the Etage Bathonien of D'Omalius and D'Or- 

 bigny, and therefore contemporaneous with those of Mamers and 

 Scarborough. In each locality* we find a predominance of land-plants, 

 and among these CycadecB and ConifercB especially abound. The 

 peculiar character, however, is marked by the EqvAsetacecB. 



This discovery enriches the fossil flora of the Oolite with an import- 

 ant number of species, and adds to our knowledge of the geology of 

 the South of Europe. [T. R. J.] 



Fossils of the Vienna Basin. By Dr. Hornes. 



[From Catalogue of Duplicates published by the Vienna Imper. Geolog. 

 Institute, 1854.] 



The following list of tertiary fossils from the Vienna basin has been 

 prepared from the duplicates of the Imperial Geological Institute of 

 Vienna, by Dr. M. Hornes. 



Numerous duplicates having been obtained in collecting these 

 fossils from various localities in the Vienna basin, it was considered 

 desirable to arrange several collections for distribution or exchange ; 

 this list represents the contents of these collections. It is true it 

 does not contain all the species of the region, but only such as were 

 sufficiently abundant to supply materials for the collections. At the 

 same time, this will be sufficient to show the chief typical forms. 



The collections were chiefly intended for distribution amongst the 

 national provincial museums and educational institutions ; others for 

 being forwarded to foreign countries. Some are for sale, and for 

 this purpose the sum of £2 1 Qs. has been fixed on as the price of the 

 whole collection of 120 species. 



1. Conus fusco-cingulatus, Bronn. 6. Ancillaria glandiformis, Lam. 



2. Mercati, Brocchi. 7. . 



3. ventricosus, Bronn. 8. Cyprsea pyrum, Gmelin. 



4. Dujardinii, Desk. 9. Kingicula buccinea. Desk. 



5. Oliva flamnnilata, Lamk. 10. Voluta rarispina, Lam. 



* Teeth of a small species of Pijcnodxts have been found at Rotzo and at Per- 

 nigotti.
