THE NAUTILUS.

the difference in the habitats of the various species when found 

 living : some were common those usually found at low tide in 

 estuaries or on mud flats ; some from rocky beaches and some 

 usually found in deep water. I found one species, the only 

 specimens I ever obtained living, in a piece of coral brought up 

 from 200 fathoms. The shells, most of them very small, were 

 remarkably well preserved. After sieving and sorting and 

 saving nothing but good specimens, I obtained 105 species and 

 over 4000 specimens, as follows.
