310 Sectional Officers’ Report. 
BOTANY. 
Rev. E. A. WOODRUFFE-PEACOCK, L.Th., F.L.S., F.G.S- 
Though so dry, from the point of view of the flora, the 
late year has been a most successful one. Mr. G. C. Druce 
visited the county during the season, and as usual has left his 
sign manual with us in the shape of new records. These are 
proved by the specimens in the hands of the Botanical Secretary 
for the Museum. A start has been made in systematically 
collecting insects in the act of cross fertilising flowers by visits 
for many purposes. 
These may be summarised so far as is at present recog- 
nised as follows :—(1) for honey; (2) for pollen; (3) for daylight 
sunning or resting; (4) for night-time resting or sleep; (5) for 
shelter from wet; (6) for victims; (7) for love-making ; (8) pollin- 
ation is also brought about by insects flying through the so called 
anemophelous vegetation and shaking out the pollen. 
The list of new species will be found in the additions and 
corrections to the Check List printed elsewhere. 
CONCETIOLGGY:. 
W. DENISON ROEBUCK, F.L.S. AND JOHN 
F. MUSHAM, F.E.S. 
The officers of the Conchological Section have to report 
that—although climatological conditions have been against their 
investigations, the weather being too fine and dry for terrestrial 
species and the extreme drought emptying nearly all the smaller 
drains which yield fresh water species, good work has been done 
during 1911. Twospecies, Vallonia excentrica taken at Cleethorpes 
in 1904 by Mr. Fred Taylor, and at Mablethorpe in 1906 by Mr. 
Musham, and Pisidium cineveum in the River Ancholme at Bishop 
Bridge, district 5 East, have been added to the fauna of the whole 
County, which now amounts to 120 species, the highest number 
authenticated for any county in the British Isles.
