virgata, da Costa); 3 Pyramidula rotundata ] 29 V allonia sp. ; 4 Cochlicopa 
lubrica, Muller ; and 3 Vertigo pygmcea. Also 4 Periwinkles ( Littorina 
litor&a) with seaweed and a small crab's leg. 
No weed seeds were found, but 81 grains of wheat in 7 birds and 
18 oats in 3 birds. Grass was found in 15 birds, bits of roots in 9, 
perianths of rushes in 4, much decayed vegetal matter in 2, a quantity 
of beetle debris in 5, chitin fragments in 1, and debris of beetle larvae 
in 1. 
May. — Eighty-two birds examined. In these were found : — 94 
Leather Jackets (75 of T. oleracea and 19 of T. paludosa ) ; 35 Click 
Beetles (34 Agriotes lineatada\& 1 Athous sp. ?) ; 10 Wireworms ; 2 Dark 
Arches Moth caterpillars ( Xylophasia polyodon) ; 8 Carabid larvae 
( Pterostichus ) ; 2 Clover Weevils ( Sitones flavescens) and 1 Sitones 
sp. ? ; 12 Hypera Weevils ( Hypera punctata) ; 6 Barynotus Weevils 
( Barynotus elevatus) ; 5 Raspberry Weevils ( Otiorhynchus picipes)’, 
16 Otiorhynchus tenebricosus ; 1 Ground Beetle ( Steropus madidus) ; 
1 Dung Beetle ( Geotrupes stercorarius)* ; 1 Rove Beetle ( Staphylinid ) ? * 
2 Sciarid larvae ; 3 Fever Fly Larvae ( Bibio sp.) ; 1 Caddis Worm ; 
1 wing of Crane Fly ( Tipula sp.) ; 3 Lepidopterous larval skins ; 
6 Millepedes [Julus) ; 1 Centipede ( Geophilus longicornis)* ; 1 Spider 
skin* ; 1 Wood Louse ( Oniscus ascellus) ; amongst the Mollusca 
were 20 Hairy Snails ( Hygromia hispida), 9 Strawberry Snails ( H . 
rufescens) , 2 Banded Down Snails [Helicella caper ata) and 1 H. virgata, 
1 Helicella cantiana, 1 Azeca tridens. One bird contained 2 Black 
Bindweed seeds [Polygonum) and 1 Chickweed seed [Stellaria media). 
In 11 of the birds 62 grains and husks of wheat were found. Nine 
contained grass, 3 moss, 2 pieces of bread, 3 pieces of roots, 1 flint chips, 
and 16 much Coleopterous debris. 
Thus the 82 birds examined in May were found to contain 245 
harmful organisms, and 66 beneficial ones, leaving a balance of 189 
on the right side. 
June. — Forty-five birds were sent in. These contained : — 25 Leather 
Jackets (17 of Tipula oleracea and 8 Pachyrrhina sp. ?) ; 4 Wire- 
worms and 1 Click Beetle [Agriotes lineatus) ; 1 Hypera Weevil [Hypera 
punctata) ; 1 Barynotus Weevil [Barynotus elevatus) ; 10 adult Dung 
Beetles [Aphodius sp. ?)* ; 1 Rove Beetle [Staphylinid)* ; 22 Carabid 
larvae,* apparently Pterostichus ; 1 Larva of the Dark Arches Moth 
[Xylophasia polyodon) ; 5 larvae of the Mottled Umber Moth [Hybernia 
defoliaria) ; 1 Tortrix larva [Tortrix sp. ? ) ; 3 Lepidopterous larvae

In 4 birds were found 13 grains of wheat, and in 7 birds remains of 
about 14 green cherries. 
Miscellaneous matter found included grass in 7, leaves in 1, and 
much fragmentary beetle debris in 2. Thus these 45 birds contained 
94 harmful organisms and 34 beneficial ones, excluding grain, mostly 
husks, leaving a balance of 60 harmful insects, etc. 
j UL y. — In this month only 17 birds were sent in, and these contained 
very little in their crops, some being almost empty ; in them were found
