During the past year, the most important acquisition made by the Geological Department 

 consists of a very extensive Collection of Fossils, chiefly Irom Germany and Switzerland. 

 This Collection has so recently arrived that a very exact account of its contents cannot yet 

 be furnished ; it consists of more than 4,000 Specimens; and comprises series from various 

 formations and localities, of which the following are the most important: 



From the Green-sand of Essen ; from the Eocene of Kressenberg in Bavaria, and the 

 Swiss Alps. 



From the Pliocene and Miocene formations of Wurtemburg, Baden, Mayence, &;c. 



From the Molasse of St. Galle, in Switzerland. 



From the Cretaceous formations of tfie Sentis Alps, in Appenzell. 



From Geningen, a very extensive Collection of Plants, Insects, &c. 



Considerable additions to the Collections have also been made from the Lithographic 

 Limestone of Solenhofen, and the Devonian of the Eif'el. 



Other Collections have been received from the Continent, but they are of Hmited extent,, 

 though some of them possess much scientific interest; especially a series of Mammalian 

 remains from different parts of France, which includes the following species : 



Dinotherium ; represented by a lower jaw, showing, in part, the teeth of the young and 

 adult animal combined ; and other remains of the same animal. 



The Tapirotherium, and two kinds of Rhinoceros, hitherto wanting to the Museum 

 Collection, are also represented by characteristic bones; and of the Anchitherium and 

 Dicroceras, additional portions of the Skulls and Skeletons form part of the series. 



A considerable series of Echinidse has also been received from France. 



From the English Geological Formations, the Gallery has been enriched by many speci- 

 mens of Fossils, of which the most important are as follows : 



Many detached portions of the Skeletons of different species of Ichthyosaurus and Plesio- 

 saurus, together with some neai ly perfect Skeletons, from the Lias of Whitby and Lyme 

 Regis ; and, from the same localities, some Fish remains, in very fine state of preservation, 

 have been obtained. 



A fine Skull of the Lias Crocodile, the Teleosaurus, has been procured from Whitby. 



Many Iguanodon remains from the Isle of Wight. 



From the London Clay of Sheppey, among other less striking Specimens, has been received 

 the Skull of an enormous Turtle, by far the largest hitherto found.
