The species of the genus Vertigo referred to in the following 
Notes are — 
Vertigo anti vertigo (Drap.). 
This Vertigo as a recent (or living) species is, where the condi- 
tions are favourable, of comparatively frequent occurrence. It is 
recorded in Roebuck's " Census " from six different counties, in- 
cluding Sutherlandshire — to these I am able to add another, viz., 
Fifeshire. Some time ago Mr. J. W. Paterson of Edinburgh, sub- 
mitted for my inspection a number of shells obtained by him near 
Largo during last autumn, and among them I observed this species. 
The fossil distribution of Vertigo antivcrtigo in Scotland seems to be 
very limited, as yet I only know of its occurrence in the Elie 
post-tertiary deposits described in the Proceedings of the Royal 
Physical Society, Edinburgh, vol. x., p. 334, and since in what 
appears to be an older deposit than that described in the Pro- 
ceedings referred to. This deposit — which also occurs at Elie — 
was exposed while some drainage operations were being carried 
out. This Vertigo was comparatively common in both deposits. 
Vertigo pygm.ea (Diap.). 
This is a common species in many places ; at least I have 
found it so both in the east and west of Scotland. Last autumn 
I collected a good number of specimens among the ruins of an 
old boundary wall near Elie, and J. W. Paterson showed me 
specimens collected by him near Largo. I have also obtained it on 
Inchkeith. Fife is not included in the "Census" of distribution 
for this species.
