The Conchological Section was but poorly represented at the 
excursion, not one of the officers of the Section being present, and

shells and 7 slugs—the remaining 21 being land shells. ‘The most 
noteworthy shells were Pupa secale brought from the western slope

log of wood as Avion subfuscus, A. circumscriptus and Limax agrestis, 
all lying close enough together to admit of being simultaneously 
covered by a penny piece. As a matter of course the submontane 
and calcareous species, Helix rupestris, Balea, and Clausilia dubia 
were common, and Helix rufescens was particularly abundant in many
