Easily distinguished by its large size (18 millim.) and uniform 

 luteous colour. Abundant just above high-water mark ; it ranges 

 from the Gambler Islands to the East Indies.

This, like the preceding species, lives just above high-watermark, 

 and has the same extensive geographical range. 



It is subject to considerable variation in shape and colour. The 

 type varies from bluish white to luteous, and is girdled with from 

 four to six narrow chestnut bands on the body-whorl. Varieties of a 

 uniform bluish-white, corneous, brownish, or orange-brown are not 

 infrequent, as well as one of an orange-brown with three chestnut 

 bands. The spire is marked with minute radiating grooves.

Common on the margins of mangrove-swamps. Mr. Brazier 

 records it from Torres Straits. I took a few examples at Samoa and 

 Wallis Islands. Mr. Nuttall obtained the type specimens at the 

 Sandwich Islands. I have also received examples from New 

 Caledonia.
