A Shells from quarry tip. 
B_ From the soil to the right of quarry: 24% feet deep or more, 
C From the dirt band on top of the small pit, approximately old soil. 
D_ From stone band just above the old soil. 
E From gravel and dirt at the right-hand corner of quarry. 
F From the old soil. 
One example of Helix nemoralis was obtained from the 
__ black band of the pit, and one from the gravel, two feet 
_ deep zx sttu. The calcareous granules representing the 
internal shell of Avion were extremely abundant. It is 
notoriously difficult to determine the species of this genius 
_ from these scanty remains, and yet in all probability 
at least two forms are present—Avion ater and A. 
_ hortensis. . 
Vitrea cellaria is also an abundant form, and _ attains 
_ a large size: examples being 12 mm. in diameter. Some 
_ of the specimens are broken, and the animals have evi- 
_ dently been eaten by mice.
