L. minuta of 'Crag Mollusca.'
Given in Woodward's list; but the fragments in the British Museum are not sufficient for reliable identification.

The Bridlington shell called C. scalaris by Forbes, in Me. Geol. Survey for 1846, was most probably only C. Analis.
Probably represented by C. ventricosa, Gould, on N.W. coast of America.
On authority of Woodward's list only. Believed by S. Wood to be only A. sulcata, var. elliptica.
Rare in Crag. Common in Middle Glacial. Mediterranean, sec. Jeffreys.
