POPULAR CONCHOLOGY. 



The Tellinas are all attractive from their 

 beautiful colour and elegant shape. The ani- 



mal has the power of springing to a consider- 

 able distance, by folding a portion of its body, 

 and then suddenly extending it ; the shell 

 being closed at the same time with a loud 

 snap. They bore into the sand on the sea- 

 shore, and often become the prey of carnivorous 

 shell-fish, as the Buccinum, &c. The valves 

 are not always similar, one being occasionally 

 more convex than the other, the colours and 

 bands also differing. They are found in all 

 parts of the world. The valves in some species 

 are much more twisted than in others.
