SOME NOTES ON THE SCOTCH SPECIES OF THE 
MOLLUSCAN GENUS VERTIGO. 
By Thomas Scott, F.L.S., 
Naturalist to the Fishery Board for Scotland. 
PLATE I. 
IN the following Notes, though reference is made to the 
distribution of the recent (or living) species of Vertigo 
observed in Scotland, my chief purpose is to bring together the 
various records I have been able to collect bearing on their 
fossil distribution. The nomenclature and arrangement of 
Jeffrey's " British Conchology " are adhered to. The Rev. Canon 
A. M. Norman, F.R.S., &c., is publishing in the "Annals and 
Magazines of Natural History " a " Revision of British Mollusca" 
which will be of great value to students of systematic conchology. 
In this revision he includes the species q{ Pupa and Vertigo under 
the one generic name, Pupa, Draparnaud, and retains Vertigo as a 
sub-genus in which the two sinistral species, V, pusilla MulL_, and 
V. angustior Jeff, are included. 
The following papers will be found useful as bearing on the 
recent distribution of the species.

tory of the Environs of Edinburgh/' by William Rhind,
