 sed oysters from the Hunter River Beds were found to have their shells per- 

 forated and destroyed by a small boring annelid — Leucodore ciliata — which 

 by burrowing through the substance of the shell, causes the disintegration 

 of the valves and the death of the oyster. — On some recent Histological 

 Methods and their application to the teaching of practical Histology. — 

 On the minute structure of Polyno'é. — Mr. Haswell exhibited also 

 specimens of Alepas parasita, Quoy and Gaimard, a bai'nacle which is para-
