 Bridlington Fossils. 



In the Ornithological department, the Council are glad to 

 notice the near completion of the re-arrangement of the general 

 collection, commenced during the year 1848, according to the 

 plan noticed in the last report. The following donations 

 to the collection of British Birds are worthy of particular 

 remark. A beautiful Bustard, (Otis Mc Queenii, Gray,) shot in 

 Lincolnshire, and the only instance of the occurrence of the 

 species in Europe, has been presented to the Society by a joint 

 subscription of several of its members, who purchased it for £25, 

 and thus secured to the Museum this unique British specimen. 

 Likewise a Yorkshire killed specimen of Buffon's Skua, a rare 

 visitant of the British coasts, presented by Mr. W. R. Read. 



To Henry Telford, Esq., the Society is indebted for a very

 hybrid between the Black and the Red Grouse. 



The arrangement of " The Rudstone collection of British 

 Birds" will shortly be completed in a manner worthy of the 

 Society's appreciation of so valuable a donation. 



In the Conchological Collection may be noticed the addition 

 of another series of American Land and Fresh-water Shells, 

 presented by Mr. Joseph Clarke, of Cincinnati, to whose warm 

 interest in the Society the Council have, on former occasions, 

 had to allude.

 examples of the rare Carinaria Mediterranea, commonly known 

 as the Glassy Nautilus, and Capt. Edward Dixon, R.N., has 

 presented specimens of lanthina, from the Coast of Africa, 

 accompanied with the Ova and soft parts. An extensive series 

 of shells from the Pacific Coasts, containing many valuable 

 species, has been likewise received from Adam Crawford, Esq., 

 of Rhodes, North Berwick. 



The donations to the Antiquarian department have not been
