200 A BEAUTIFUL SHELL. 



a clam, but for this red-lined one my opinions quickly 

 changed. 



Imagine two tubes made of the finest pink and 

 white silk, stretched over delicate hoops arranged at 

 regular intervals; then think of them as endowed 

 with life and waving with a graceful motion through 

 the water, and you will have a faint idea of their 

 exquisite texture and elegant appearance. 



I kept my mollusk as long as possible in the jar of 

 water, and then, not bearing to part with him, I 

 quickly deprived him of life and tookThis shell home

 covered by their spouting up the water as the men walked over 

 the sands where the}- inhabited. As I suppose it to be a new 

 kind, I have given a figure of it in the annexed plate. 'Tis a 

 thin, brittle shell, smooth within and without ; one valve is 

 furnished with two front and two lateral teeth ; the other has
