PLATE CIX. 



Geographicus. The ground colour is pale, or whitish, sometimes 

 tinged with faint reddish, and the spire with a rosy hue ; the spots 

 are chesnut, and of no very determinate form, being intersected with 

 waves and spots of the paler hue in an irregular manner. The 

 tout ensemble of those variations, are, however, pleasing, and the 

 shell itself is of a size too conspicuous to be neglected in a cabinet of 

 conchology ; it is represented in its natural size in the annexed plate. 



Gmelin, speaking of this species, says " Habitat rarior in 

 Oceano Tndico et Africano."" It is now well known as a native of 

 the Indian and African oceans, and is not particularly uncommon.
