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 will he 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 
Staitlies fishing-boat in the course of last summer, was 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 Palseontographic 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
