The shell differs from A. depressa 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, breadth 9.5 mill., 

 and length 12.4, breadth 8 mill.
