searches of Madame Power. In this shell a portion has been broken 
out near the middle of the left side, and not far from the sinus of the 
aperture. The opening was of a semilunar form, about 12 inches long, 
with an average breadth of half an inch. A new deposit of testaceo 4

But the most extraordinary circumstance is this ; that a singe,
