Of other orders of insects many species were taken, but 
these await examination and diagnosis. 
For the ConcHoLocicaL Section, Mr. J. E. Crowther 
reports :—Arriving at Thorne, somewhat earlier than the time 
stated on the circular, we made our way to a drain near the first 
turn-bridge, which had yielded very good results in the first week 
in May. On our way we found Helix nemoralis very sparingly 
on the road side, but fine in size and colour. The drain having 
been recently cleaned out, yielded nothing but Lzmna@a pereger 
and Z. stagnalis of small size. Helix cantiana was very abundant 
on the sloping banks, along with H. hzspzda and Succinea putris. 
S. elegans was very plentiful close to the edge of the water. In 
the big ditch alongside the canal Valvata piscinalis was plenti- 
ful, with Vevzpara vivipara and Limnea truncatula, on the bricks 
of the bridge. Sphaertum pallidum occurred in the canal. In 
the road side ditch on the way tothe moor Bythinta leachit and 
B. tentaculata were plentiful, while young Z. pereger occured in 
great numbers, together with several species of Planorbdis. In 
a drain near by Physa hypnorum and Limnea glabra were found. 
The only species found on the moor itself was V7¢rza alliaria, 
obtained by Dr. Corbett a few days before the meeting. 
The total number of species seen was thirty, composed of 
four slugs, seven terrestrial, and nineteen aquatic species. The 
complete list is as follows :— 
Agriolimax agrestis. | flelix cantiana. 
Vitria alliaria. 5,  Aispida. 
Arion ater. »,  aspersa. 
5,  hortensis. Felix nemoralis.
