COUNCIL FOR 1850. 9 



Very choice examples of Modiola nigra from the Firth of 

 Forth, Bulla acuminata and Crania Norwegica, from Loch 

 Fyne, Pleurotoma Boothii, and Trochus millegranus from 

 Lamlash, have been added to the Cabinet of Shells. In the 

 last named locality, the Keeper of the Museum, by dredging, 

 obtained Lima hians, in its nest, and the series of specimens, 

 now displayed in the Museum, constitutes, it is believed, by far 

 the most complete illustration of this feature in the economy of 

 the Lima, that has ever been obtained. The Limas, thus 

 dredged in their nests in Lamlash Bay, were of all sizes, from 

 the very young up to the adult, and it vcill be observed, that the 

 cavity of the nest presents no aperture corresponding to the 

 Siphonal aperture in the nest sometimes made by Gastrochsena, 

 the capacity of the interior being generally eight or ten 

 times that of the contained animal and shell. One of the very 

 scarce forms of Buccinum, referable to Buccinum acuminatum 

 of Broderip, obtained at Redcar, by Mr. D. Ferguson, from a 

 Staithes fishing-boat in the course of last summer, vs^as subse- 

 quently presented to the Museum by the British Natural- 

 History Society. 



Through Mr. Edward Wood, of Richmond, the Society has 

 received a Slab of Micaceous Sandstone from the Mountain 

 Limestone series, having upon its surface in relief a Sea Worm 

 allied to Nereis. 



The Council are glad to state that Professor King in his 

 valuable work on the Fossils of the Permian system, published 

 by the Pateontographic Society, has derived assistance from 

 an examination of the specimens of Fish in Magnesian Lime- 

 stone in the Society's Museum, from which several of the 

 plates in his work have been figured. 



The Council have the pleasure of noticing the completion of 

 the arrangement and fitting up of the Rudstone Collection of 

 British Birds, which is found, as was anticipated, as valuable to 

 the student as attractive to the general visitor. 



Of the Donations to the Antiquarian department of the 

 Museum during the past year, which have been very few, there 

 are none which require any particular notice. 



In their last report the Council stated, that the first part of
