Many specimens were taken, of considerable range in size. This is still another 
of the relict fauna of an area once oceanic. They also reach to the fringes of the 
Andes, a distance probably exceeding three thousand miles from salt water at the 
mouth of the Amazon. Like their marine relatives they continue the habit of swal- 
lowing water or air, whichever may be the more convenient, and taking on an almost 
spherical outline.
