THE HUNCHBACK SCALLOP 45 



PLATE XV 



THE HUNCHBACK SCALLOP (3) 



It is very easy to see why this creature is called 

 the " hunchback," for although when it is quite 

 small it is shaped just like other scallops, it alters 

 in form very much as it grows bigger; so that 

 really it sometimes looks as if it had been 

 crumpled up when it was quite soft, and had 

 never recovered from the squeeze. Besides this, 

 the two valves are not alike, as they are in 

 other scallops, for while one is always very 

 deep and rounded, the other is nearly flat. So 

 when the animal is alive it really has a kind of 

 "hunchbacked" appearance; and if you found 

 its two valves lying apart from one another you 

 would hardly believe that they could both have 

 belonged to the same creature. 



The colour of the hunchbacked scallop is 

 white, mottled with brick-red.
