animals which are thrown up by the tide. Many of the shells thrown upon the shore are found 

 to be perforated with a small round hole : this is done principally by the different species of 

 Natica. They have the power of perforating shells, it is generally supposed, by discharging an 

 acid which decomposes the shell, and through the aperture they extract the juices, and destroy 

 tht lives of the otherwise' secure inhabitants. Their foot is very large, so as to completely 

 envelope the objects on which they prey. In moving, they burrow in the sand, so as to be 

 almost entirely concealed by it, and their place is generally indicated by a small heap of sand. 

 The singular nidus in which the animal of Natica deposits its eggs has been an object of much 

 curiosity and speculation. It is a mass of saud glued together into the shape of a broad bowl, 

 open at the bottom, and broken at one side. Its thickness is about that of an orange-peel, 

 easily bent without breaking when damp, and when held up to the light will be found to be 

 tilled with little cells, arranged in quincunx order. Each of these cells contains a gelatinous 

 egg, having a yellow nucleus, which is the embryo shell."
