 Bulimus virido-striatus. Lea. 

 Ilelix galactiles, var., Grateloup. 



Hab. Island of Temple, Philippines ; Cuming. 



This species differs from the preceding in being of a 

 larger and lighter growth, and in being constantly encircled 

 beneath the suture with a broad white band, however 

 variable may be the pattern and colour in other respects. 

 Mr. Cuming observed that this was the only snail in the 

 Philippines which was attacked and eaten by the birds.
