PLATE XLIX. 



reversed shells. These exhibit spots or marks of a brown colour, 

 more or less intense, sometimes disposed in longitudinal lines or 

 undulations, and those lines are either continuous or intersected ; 

 The intersecting lines are usually paler, and these dividing the 

 stripes at regular intervals contribute to give the shell a tesselated 

 appearance of deep or fuscous brown spots upon a yellowish ground : 

 Generally these longitudinal bands are confined to the first or second 

 whorl, appearing pretty numerous on the first, more sparingly on the 

 second, and entirely disappearing beyond. Most commonly these 

 longitudinal stripes are interrupted by a broad band of white, com- 

 mencing at the upper part of the lip and passing entirely round the 

 whorl below the sutural line. There is also sometimes a spiral band 

 that traverses those whorls about the middle, and occasionally speci- 

 mens occur in which more than one of those pale spiral bands traverse 

 the middle of the shell. In the example now before us there is no 

 such spiral band surrounding the middle of the shell ; the streaks are 

 longitudinal and somewhat undulate but not interrupted except by 

 the broad whitish band which passes below the suture, and at the 

 verge of which they abruptly terminate. Some of the above-mentioned 

 varieties accord extremely well with those which Linnaeus des- 

 cribes from specimens in the museum of Ulrica, Queen of Sweden, 

 namely, « Jlava, /3 Jlava lineauna alterave purpura^ y 'pallida Jasciis 

 iransversis fuscis confertis. 



Those shells are of the land or terrestrial tribe, inhabiting the 

 forests of Cayenne and Guinea, and also those of the West Indies, 

 Pulo Condore, and China. The individual specimens we have re- 

 presented are from Prince's Island, in the Pacific Ocean, the spe-
