44 RAMBLES OF A NATURALIST. 



which, at first sight, seems merely like an irregularly 

 puckered opening. But watch it for a few moments, 

 see how it opens and protrudes a large proboscis, 

 furnished with three pairs of jaws, and possessing a 

 diameter which equals that of the body, within which 

 it is enclosed as in a living sheath. Well ! is it not 

 wonderful ? Is there any animal which can contend 

 with it for the prize of decoration ? the corslet of the

 over its amber and coral fringes. 



Let us next examine these two Cirrhatulae which 

 belong to one and the same species, although they 

 differ so much in colour. The one which was cap- 

 tured under a stone that had been washed several 

 times daily by a rapid current, is of a dull red, 

 relieved by golden markings. The other, found in

 coloured yellow. See how they lengthen their
