The shell differs from A. depreasa chiefly in having the spire pro- 

 jecting more above the insertion of the outer lip, and the columellar 

 appendage usually more developed. The living animal is smaller 

 and its jaw has many more plaits. It is a species of the lowlands, 

 while A. depressa lives at a considerable elevation on the mountains. 



Two specimens before me measure: length 14, bnadth 9.5 mill., 

 and length 12.4, breadth 8 mill. 



A. DEPRESSA (Rang). PI. 63, figs. 53, 54, 55.

 behind ; greenish, more or less olivaceous or brownish ; spire a little 

 projecting, sometimes sunken. Right margin thin, slightly reflexed 

 toward tie interior, dilated at the spire and projecting beyond the 

 apex, at its junction with the columella. Columellar appendage thin ?
