POLYZOA. 



A SUB-Fossii. PoLYzooN FROM CAI.CUTTA. — In the Rccords of 

 the Geological Survey of India, vol. xxi, p. 175, Mr. E. Vredenburg 

 describes briefly an oyster bed discovered under one of the streets 

 of Calcutta. Several molluscs were found in this bed, all of them 

 belonging either to freshwater species or to species still found in 

 brackish water in the estuaries of the Ganges. Some of the oyster 

 shells were incrusted b}^ a Polyzoon, which was diagnosed in the 

 Museum as a species of Lepralia. A fragment was submitted 

 through Mr. R. Kirkpatrick to Mr. A. W. Waters, who reports 

 upon it as follows : — 



" Zoarium is in places in two layers, and from the fragment 

 it looks as thoucrh there mav have been two or more layers.
