84 THE ZOOLOGIST. 
And lastly, private enterprise having at length filled up the gap 
caused by the Duke of St. Albans’ parsimony and neglect to 
provide what he is paid by the State for providing—public hawks— 
we have now a Central Depét and School of Falconry, with an 
ample staff, at the service of all who wish to try their hands at the 
noble art, however little time they may have to devote to its 
practice. This result has not been attained without very heavy 
sacrifices; in return, may I bespeak one kind thought for the 
promoters of the Revival of Falconry from every reader of ‘ The 
Zoologist’ whenever he may see temptation, in the shape of a 
hawk of any kind used in Falconry, within range of his deadly 
breech-loader ! 
THE LAND AND FRESHWATER MOLLUSCA OF SUSSEX. 
By tHe Epiror. 
THE Lists of Land and Freshwater Mollusca which have from 
time to time been prepared by conchologists in Sussex have 
reference, for the most part, to restricted areas in the county, or to 
the particular localities in which the authors of these lists reside. 
So far as we are aware, no general catalogue for Sussex has been 
published ; and in the following pages, therefore, an attempt will 
be made to supply a want which may possibly have been expe- 
rienced by conchologists, not only in Sussex, but in other parts of 
the country. At the same time it is hoped that a catalogue, such 
as the present, may be the means of suggesting to many readers of 
‘The Zoologist,’ and to their friends, a new field for research, or at 
all events of directing their attention more particularly to a branch 
of Natural History which upon investigation will be found to 
possess much attraction, and which, at present, scarcely receives 
that attention which it deserves. 
In the preparation of this catalogue the Editor has been assisted 
by several friends in Sussex, to whom he desires to express his 
obligations, and has availed himself of the information contained 
in all the local lists for Sussex which he has been able to procure. 
The principal sources of information cs be briefly stated to be 
the following :—
