COUNCIL FOR 1851 . 
9 
cases with Mr. Bean, Mr. Alder, Mr. Hanley, and other well 
known authorities in this branch of Natural History, and the 
Council trust that the correctness of identification may be 
relied upon throughout. The Council invite attention to an 
ingenious method (invented by the Keeper of the Museum) for 
the purpose of insuring the security of the smaller and more 
delicate species, which in the course of time suffer by exposure 
when mounted in the ordinary way. 
The completion (so far at least as the Marine species are 
concerned) of the History of British Mollusca by Professor 
E. Forbes, and Mr. Hanley, has enabled the Keeper of the 
Museum to draw up and print a list of all the species recognized 
as such by the authors of this work. The circulation of copies 
of this list, with our desiderata marked, will, it is hoped, 
greatly facilitate our obtaining the species yet wanted to com¬ 
plete the British Collection. 
In the class Badiata, there have been added in the British 
series some choice specimens of Goniaster equestris, from 
Lamlash Bay, Arran, and a carefully prepared specimen of 
Comatula, from the same locality ; a valuable acquisition, as 
connecting the Starfishes with the family of Crinoidea. 
Another series of Uniones and Helices has been forwarded 
by our indefatigable correspondent, Mr. Joseph Clarke, of 
Cincinnati. 
To Mr. O. A. Moore, the Society is indebted for a very 
interesting series of Land Shells, from Chili, principally of the 
genus Bulimus, and containing several forms new to the 
Collection. 
The additions to the Foreign Collection have not been 
numerous, but are valuable. A skin of the Sable Antelope 
(Aigoceros niger), one of the rarest known species of African 
Buminants, has been presented to the Society by Mr. Armitage, 
of Harrogate. 
The Mineralogical cabinet has received, during the year, 
some fine specimens of Butile, the gift of J. B. Lawes, Esq. 
The Minerals have been revised and the arrangement of them, 
in some respects, improved; and the Council hope by an 
enlarged method of labelling, for which the cases now afibrd
