538 MR. H. B. TRISTRAM ON THE TERRESTRIAL [June 27, 
This Bulimus, the Transjordanic representative of B. attenuatus, 
is intermediate in character between it and B. pupa of Greece and 
Algeria. From the latter it may be distinguished at once by its 
olive-green colour and by its suddenly expanding fifth whorl, which 
gives it a peculiar obese appearance. From the former it is distin- 
guished by the sixth and seventh whorls increasing instead of con- 
tracting.

Common throughout the whole country, and subject to great varia- 
tions in size. The mouth is frequently six-toothed, and sometimes 
only five-toothed.

Common. For the distinctions between this and the last species,
