328 Yorkshire Naturalists at Wentbridge 
Dredging in the River Went yielded Paludestrina jenkinsi in 
abundance, Spherum corneum, and Valvata piscinalis. Dr. 
Corbett reported having found Planorbis spirorbis and Physa 
hypnorum at Kirk Smeaton. 
LEPIDOPTERA.—Mr. B. Morley reports that ten species of 
butterflies, and a number of moths, were observed, but the 
only species worthy of note were Pararge egeria and Cucullia 
verbasct. 
FLOWERING PLANTs.—Mr. W. H. Burrell writes :—The 
necessity of approaching Wentbridge by road, across the 
junction of the Coal Measures and Magnesian Limestone, 
contributed to the interest of the meeting by bringing into 
prominence, early in the day, certain elements in the flora 
common to one soil but more or less rare or absent from the 
other. Meadow Cranesbill made a great show at Thorpe 
Audlin, but during a twenty mile cycle ride from Leeds, via 
Wakefield and Ackworth Moor Top, it was not noticed until 
the Doncaster-Pontefract road had been crossed. 
Brachypodium pinnatum and Bromus erectus, two grasses 
rarely seen off the Permian tract, were in abundance, and 
together with Rock-rose, Lady’s fingers, Dropwort (Spirea 
filipendula), Potentilla verna, Squinancywort (Asperiula cynan- 
chica), Small Scabious (Scabiosa Columbaria), Blue Flea-bane 
(Evigeron acre), Ploughman’s Spikenard (Inwzla squarrosa), 
Greater Centaurea (C. Scabiosa), a white flowered form was 
seen; Clustered Bellflower (Campanula glomerata), Hound’s 
Tongue (Cynoglossum officinale) and Gromwell ( Lithospermum 
officinale), were recognised as indicators of limestone soil. 
Other plants seen during the day, more or less common on dry 
soiis and not confined to limestone were :—-Field Mouse-ear 
(Cerastitum arvense), Mountain St. John’s Wort (//ypericum 
montanum), Bird’s-foot (Ornithopus perpusillus), WRcse-bay 
(Epilobium angustifolium), Teasel (Dipsacus sylvestris), Yellow- 
wort (Blackstonia perfoliata), Centaury (Centaurium umbellatum), 
Great Mullein ( Verbascum Thapsus), Black Horehound ( Ballota 
nigra), Wild Basil (Clinofodium vulgare) and Hemlock { Conium 
maculatum), In or near the river were Great Watercress 
( Radicula amphibia), Water Starwort (Stellarva aquatica), Yellow 
Waterlily (Nymphea lutea) Arrowhead (Sagittaria sagittifolia) 
and Reed Poa (Glyceria aquatica). 
A useful reminder that living organisms have a measure of 
adaptability, and will not always restrict themselves to the 
type of habitat in which they are usually found, was afforded 
by a tall plant of Figwort (Scrophularia aquatica) growing.on a 
dry scree in a quarry. A parallel case of a plant of Brooklime 
(Veronica Beccabunga), of gigantic proportions, having been 
found on a dry roadside heap was cited, but no satisfactory
