This species belongs to a peculiar aberrant group of the genus 

 Achatina, of which the type seems to be Ach. columnaris. The co- 

 lumella is not exactly truncated, but rather contorted, and forms a 

 prominent angle, which appears similar to the truncated columella 

 of the true Achatinas. To this same group may be referred another 

 very distinct and beautiful species, collected by Mr. Lattre in Cen- 

 tral America, and making, like all formerly described species, part 

 of the rich collection of Mr. Cuming.
