and H. cellavia, and adults of Avion ater vars. aterrima and 
castanea. Auster Wood was then searched, and some heaps of 
stones yielded numerous species, including Helix nemoralis, 
Buliminus obscurus, Hyalinia helvetica, the var. hyalina of Cochlicopa 
lubvica, etc., and on sticks were found Hyalinia radiatula, 
H. crystallina and H. alliavia. Pillow Wood was next examined, 
but yielded nothing but a broken example of Hygvomia granulata 
and abundance of Pyvamidula votundata. In both woods the 
pretty little slug Avion intermedius, in its var. grisea, occurred 
plentifully on bits of wood. 
By the roadside near these woods were found numerous 
examples, in many varieties, of Helicella virgata. 
The great discovery of the day was made by Messrs. 
~ Peacock and Stow, who found A zeca tridens not uncommon on a 
patch of ground about three-quarters of a mile in area, this 
being only the second locality for Lincolnshire, and an entirely

new record for Vice-County 53, Lincoln South. 
Including this, twenty additions were made to the previously 
known list for the Bourne district (16 North of the Lincolnshire 
scheme), for which 50 species are now on record—and the 
Conchologists felt wel! rewarded with the success of their 
_ investigations. 
The Rev. E. Adrian Woodruffe-Peacock writes on the 
flora :—From the point of view of Botany, the Bourne meeting 
was a most successful one. Some 250 notes were taken during 
the day. Though the soils were not as varied as at Nocton 
they furnished more true rarities. The best finds of the day 
~ were as follows:—The Well Head supplied Eupatorium cannabinum, 
Equisetum limosum and its variety, and E. palustve. The brick pit 
in the Oxford clay Vicia tetvasperma, which is yet unrecorded for 
the first six natural history divisions of the County. Bourne, 
Auster and Pillow Woods gave Calamagrostis epigetos, Carex vemota, 
Euphorbia amygdaloides in flower and seed. Melampyrum pratense, 
_ Pyrus torminalis growing freely enough, Sanicula, Scrophularia elata, 
a second record for the whole County. Viburnum opulus, and 
_ Vicia sylvatica. A brick wall top at Bourne gave Sagina procumbens
