YORKSHIRE NATURALISTS* UNION. 
At the Askern meeting Mr. J. W. Taylor reported that besides^ 
looking for land and fresh water shells, several mole-hills in 
the low-lying fields were examined for sub-fossil shells, which are 
very plentiful in some places. In all thirty-three species were 
found, and, as might be expected from the district, the greater 
part of these were aquatics. Of this number eight were found in 
the sub-fossil state only, seventeen in the living state only, and 
eight were found in both. The best record of the day, a fine var. 
acuminata of Valvata piscinalis^ was taken in Campsall Park. 
At Guisborough, probably the richest district visited during 
the summer, Mr. Roebuck reported twenty-four species, eight of 
these being slugs and sixteen terrestrial shell-bearers, no water 
shells being seen or even looked for. During this excursion 
Kildale was visited for the purpose of verifying the record of 
Acanthmula lamellata at that place. This was soon done, several 
being found, all of which were white or whitish, a form not before 
known to exist, and will probably be described as a new variety 
by Mr. Taylor in his Monograph. 
The section is carefully considering the steps to be taken for 
the speedy completion of the list of Yorkshire Mollusca, already 
partly printed, and the active co-operation of the Leeds Concho- 
logical Club will be given in doing this, under the guidance of 
Mr. Taylor. 
The following were elected for 1907 : — 
President — J. E. Crowther, Elland. 
Secretary — W. Denison Roebuck, F.L.S., Leeds. 
Representative on Executive — J. E. Crowther. 
Representative on Committee of Suggestions — ^J. W. Taylor. 
Botanical Section. — Mr. J. F. Robinson writes : — It can 
again be reported of the Phanerogamic Section that there is a 
very real and continued interest in plant study (floristic) in the 
field, and this is borne out by the full and detailed reports that 
have appeared in the "Naturalist" after each Y.N.U. excursion. 
Further, in the same journal, during the year now nearing its close, 
there have appeared important notices of discoveries made by the 
private enterprise of members of the Union or of the affiliated 
societies. 
In the Spring, near Ingleton, a very comprehensive list of 
plants was made out by Dr. G. W. Smith whilst pursuing the 
important work of the Botanic Survey of Yorkshire, and Mr. C. A. 
Cheetham added to the above. Very excellent results, too, were 
obtained at the Whitsuntide excursions to Flamborough, and 
from copious notes made on the spot by the many botanists 
who attended, one had a most complete knowledge of the spring 
flora of the great chalk headland. One species had not 
previously been noted there, the little grass, Aira prcecox. Askern
