shell, for the outside is covered with a pearly enamel, 

 and when it is held in the light it is iridescent in 

 many places. 



11 This shell is found on the shores of the China 

 Sea, the Yellow Sea, and around the Philippine 

 Islands and the Formosa Islands." Lucy. 



Shells of Torrid Zone. 

 "The Cassis testiculus resembles in many respects 

 the Cassis vibex. It is somewhat smaller, being only 

 about two inches long, and about an inch and a quar- 

 ter in thickness. It is of a pink-white color, deeper 

 in some places than others. There are grooved lines 

 running around the shell parallel to the suture, and 

 rows of ribs crossing them at right angles. The 

 outer lip turns back like that of the Cassis vibex, and 

 has brown stripes crossing it at right angles to the 

 edge. The aperture is longer and narrower than 

 that of the Cassis vibex, and there are larger teeth 

 on the inside of the outer lip. The inside of the 

 shell is white. The inner lip is white, and has teeth, 

 which are smaller than those on the outer lip. At 

 the base of the aperture there is a deep canal. The 

 spire is of a lighter color than the body whorl. The 

 apex is sharp, and is white. The suture is not deep. 

 This shell is found on the shores of Ceylon, the Lac- 

 adive and Maldive Islands, Sumatra, Borneo, and 

 New Guinea." Bessie.
