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

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

 from the Gambier Islands to the East Indies.

 This, like the preceding species, lives just above high- water mark, 



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 bauds 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-hrown 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.
