 Another very variable species, particularly in its colouring and in 

 the characters dependent upon its epidermis. Numerous, however, 

 as its varieties are, and abundant as the species is, it does not ap- 

 pear to have been described either by Lamarck or De Ferussac ; in- 

 deed, I have not been able to find any species nearly approaching it, 

 except Helix ventricosa, De Fer., w^hich is figured in Chemn. vol. ix. 

 f. 1007, 1008, and which somewhat resembles the banded variety 

 of our shell. The following varieties have been brought by Mr. 

 Cuming : — 



a. Shell white, last volution pale green, which is darker in its an- 

 terior part. From the island of Rumblon. 



b. The same as a, but having a dark brown band surrounding the 

 columella. On some specimens of this variety the remains of a dark 

 brown epidermis is to be seen about the anterior part of the last vo- 

 lution. From the island of Burias. 



c. Shell white, with a pink band surrounding the columella, and 

 scattered remains of a dark brown epidermis on the last volution. 

 From Temple Island. 



d. Shell white, with a dark brown band surrounding the colu- 

 mella, and scattered remains of a dark browni epidermis on the last 

 volution. From the island of Burias. 



e. Shell rose-colour, with scattered remains of a dark brown epi- 

 dermis about the anterior part of the last volution. From Temple 

 Island. 



f. Shell red-brown, with a dark brown band surrounding the colu- 

 mella, and scattered remains of a dark brown epidermis about the 

 anterior part of the last volution. From Temple Island. 



g. Shell light red-brown, with a dark brown band surrounding 

 the columella, and mottled with a nearly white, hydrophanous and 

 a dark brown epidermis, which becomes altogether darker coloured 

 toward the anterior part of the last volution. From the island of 

 Burias. 



h. Shell pink, epidermis as in g. From the island of Burias. 



i. Shell white, with the dark brown columellar band and epider- 

 mis as in g. From the island of Burias, 



k. Shell white, very pale greenish toward the anterior part of the 

 last volution, with a broad dark brown columellar band, a narrow 

 brown band at the circumference of the shell, and a pale antesutural 

 brown band. From the island of Burias. 



I. Coloured as k, but with broader and darker bands. From the 

 same locality.
