 Several varieties of this beautiful species occur ; most of them are 

 marked with two brown bands, and have the circumference of the 

 columella of the same colour ; one is of an uniform pale brownish 

 colour, and another is almost entirely of a very dark chocolate colour : 

 a white line may be observed close to the suture in most of the va- 

 rieties. The following are the most distinct varieties : — 



a. Ground-colour pale yellowish ; antesutural band very dark 

 chestnut-brown; circumferential band of the same colour, and a 

 broad band of the same surrounding the columella. From Loboc. 



b. Similar to a, but considerably larger, and having a broader 

 circumferential band. From Loboc. 



c. Ground-colour of a pale brown hue ; bands the same as in a. 



d. Smaller than a. : ground-colour pale greenish brown ; bands 

 nearly the same, but very dark and brilliant. From Loboc. 



e. Ground-colour pale yellowish brown ; antesutural band softened 

 off in front ; in other respects like a. 



f. Ground-colour pale yellowish; bands pale chestnut-brown. 

 From Loboc. 



g. Ground-colour pale yellow ; bands increasing in width toward 

 the back of the mouth, where they unite, and where the brown colour 

 extends from front to back of the shell : the peritreme is entirely 

 white, and the circumference of the columella also. Found on leaves 

 of trees on the island of Siquijor. 



h. Ground-colour very pale yellowish ; antesutural band very nar- 

 row and indistinct ; circumferential band broad, pale, and rather ir- 

 regular ; lip and circumference of the columella white. From the 

 island of Siquijor. 



i. Shell entirely of a pale lemon-yellow, except only a narrow an-
