Pupa umbilicata, Drap. On liassic stone walls at Lassington, in the 

 lane leading to the hill from Over, and in many similar localities. 

 Common. 



P. muscorum, Lin. My specimens of this shell were not obtained 

 from moss, but from the withered and grub-eaten boughs of an 

 ash tree, which I broke off, at least ten feet from the ground, by 

 accident, while searching for pupae of another description. The 

 boughs, which were about an inch in diameter, had been perforated 

 in every direction by a small xylophagous beetle, and in the 

 perforations made I found a great number of the shells in 

 question. 



P. secale, Drap. Plentiful in stony districts. In any quarry on the 

 Cotteswolds. 



P. edentula, Drap. Amongst dead leaves, Birdlip, Witcomb, &c. 

 Over, Newent canal banks, in moss. 



P. pygmaea, and var. alpestris, Drap. Forbes and Hanley say, "It 

 may be taken in great numbers by laying a piece of old wood 

 upon the grass at nightfall, and examining it in the morning." 

 My specimens are chiefly from Over, between the canal and 

 Leadon, and moss on canal banks, near Sharpness. 



P. antivertigo, Drap. Same locality as above. 



P. pusilla, Miiller. In damp moss in the fields on the upper lias at 

 Birdlip, Cooper's Hill, and near Sharpness Point. 



Balea fragilis, Drap. Matson, in a small grove between the church 

 and the entrance to Mr. Butt's farmyard, under the loose bark of 

 the horse chestnut trees. 



Clausilia laminata, Montagu. On beech trees. Common at Birdlip. 



C. plicatula, Drap. Birdlip, in the wood, at the base of the oolitic 

 formation, amongst or near to patches of Chrysospleniura. 



C. nigricans, Maton and Rackett. ("ommon with C. laminata, under 

 stones, and upon stone walls and trees, throughout the 

 district. 



Zua lubrica, Miiller. Under stones, in moss on banks of canal and 

 in fields at Birdlip. 



Azeca tridens, Pulteney. With above, particularly abundant in 

 some seasons on the canal banks. 



Achatina acicula, MUller. Barnwood, at the roots of grass, in a large 

 field through which the brook runs, between the church and 

 Gloucester. 



Succinea putris, Lin. On aquatic plants and mud near small streams. 

 Common. Over, on the banks of the canal where var. Pfeifferri is 

 very common.
