 look somewhat like a pair of wings, and 

 the large white ones, like Figure 57, are 

 often called Butterfly-shells.

 a small creature with very beautiful 

 shells, while the Gray Chiton (Figure

beauty, being of a dull, ashy color. It often lives 



under stones. Figure 60 shows the 



Mossy Chiton, which is so named 



from the great number of stiff hairs 



on the border of its mantle; while 



Figure 61 shows a large species with 



very regular shells. 



Besides the Chitons, you will prob- 

 ably find specimens of the Purples. 



There are several of these, also; a Figure 04. 



picture of one of the common ones 

 being shown in Figure 62, and an- 

 other in Figure 63. 



Both of these pictures are some-

 ) cimens, but they show very well the 

 shape and appearance of the shells. 

 The Purples are rather active crea- 

 tures, though at low tide you will
