122 THE NAUTILUS. 



7. 0. inornata Say, frequent. — Some years ago I found a 

 specimen of Polygyra ihyroides in the body whorl of which there 

 were two 0. inornata, on opposite sides, entered through holes 

 made in the shell; inside of the apical whorls of the same was 

 one Gastrod. intertexta; all had been feeding there, and of the 

 victim's body only a few scant remnants were left.
