James Bennie of the Geological Survey ; in the material there 
were land and fresh-water shells in considerable abundance, and 
among other rarities this Vertzgo was of frequent occurrence. I 
obtained no fewer than six species of Vertigo in the material sent 
to me from the deposit referred to, viz., Vertigo antivertigo, V. 
Dygmea, V. substriata, V. angustior, V. edentula, and V. minu- 
tissima.. ‘The presence in such numbers of Vertigo angustior, as a 
fossil at Elie, points to its more frequent occurrence in Scotland 
when this deposit was being formed than it appears to be now, and 
also proves its claim to be an indigenous species. 
VERTIGO EDENTULA (Drap.). 
As a recent shell, this species, though widely distributed, is not 
very plentiful. As a fossil it occurred in the same deposit with 
the last. It is also recorded by Mr. David Robertson, F.L.S., from 
the Arctic shell clays at Garvel Park, near Greenock.* 
VERTIGO MINUTISSIMA (Hartm.). 
This pretty shell is still very local and rarein Scotland. It is not 
the smallest of our Vertigos, though the name might lead one to 
suppose it was. There are seven specimens of this shell in my 
collection collected among the debris at Salisbury Crags, and 
none of them can be considered very small comparatively. In 
Rhind’s List of Land Shells found near Edinburgh, and published 
in 1836, the following are recorded—/uga pygm@ea, King’s Park, 
Pupa edentula, Roslin, King’s Park, and Pupa cylindrica, Salisbury 
Crags. This last seems to be Vertigo minutissima (Hartm.), not 
Ffelix Cylindracea (Da Costa), which, according to Jeffreys, 
appears to be Pupa umbilicata, Drap. (Dr. Norman in his Revision 
of the British Mollusca restores Ia Costa’s name, Pupa cylindracea), 
and what makes it more likely that this Vertigo is referred to is, 
that Dr. Rhind records Pupa mvcorum (= £. umbilicata?), Pupa 
marginata and Pupa bidentata, all from the King’s Park, but he 
only records Pupa cylindrica from Salisbury Crags which is the only 
known habitat for Vertigo minutissima. If my conjecture is right, 
this rare species has been known as a resident among the debris of 
Salisbury Crags for a much longer time than is usually supposed.
