time, as well as the Fossil Bird from Solenhofeii. 



In Room V, the remains of the Hippopotamus and those of the Carnivora and Cetacea, 



have been entirely re-arrang:ed, and many specimens, not hitherto exhibited, have been 



incorporated in the general Collection. 



The Specimens acquired during the year have been under examination with the view^ of 



determining the species previous to their entry in the inventory, and the following have 



been registered : — 



Plants 537

The most important acquisition during the year is the Collection of Solenhofen Fossils 

 purchased of Dr. Haberlein, of Pappenheim. These consist entirely of Vertebrate Animals, 

 and include the remarkable Fossil Bird brought recently under the notice of the Royal 

 Society in a Memoir communicated by Professor Owen, in which the specimen is described 

 under the name JrchcBopteryx macrurus. Three specimens of Flying Lizards {Pterodac- 

 tylus), two being of large size (the largest occupying a slab of the lithographic limestone of 

 4 feet in length, and 16 inches in width); a remarkable Lacertian reptile described by 

 Von Meyer under the name Pleurosaurus Goldfussi ; the head of a large reptile, apparently 

 the Geosaurus Soemmeringii of Cu\ier, and some smaller specimens of Reptilian remains of 

 considerable interest. The Fishes of this Collection are, for the most part, beautifully 

 preserved in flat slabs of the lithographic stone (160 in number), and include some of the 

 most striking of the specimens exhibited in the cases devoted to the Fish remains. 



The additions to the Vertebrate series from various quarters are 334 in number, of which 

 the following are the most important: —
