The almost barren record of Pritisb Eocene Polyzoa lias been remarked 

 npon by previous autbors, but I am afraid that we owe tbe barrenness to 

 the want of researcb rather tban to tbe scarcity of sjtecies. Mr. liusk 

 describes three species from the London Clay at Jligbgate, found in tbe 

 collection of Mr. Wetlierell, 'Geo. Mag.' vol. iii., -luly 1800: —

The ^Ffmhranipora described by 'Mv. Bnsk is rather more linear than tli(> 

 more recent form generally met witli round our coast ; but some tinu; 

 .since Professor iludd ' sent mo a specimen of what I consider to be refei'- 

 iible to the ^^. Lacroixii, and this was from the oyster beds of Col well Bay. 

 it dilfered from ]\Ir. Busk's figured specimen, but as the species varies 

 very mucb in habit, this I considered of but snudl consoiiuenoe. The 

 value of the specimen sent was this. When tbe c"lls .separated in the 

 lino with tbe side walls I was able to detect the ' Rosettenplatto ' or 

 communication pores tbrougb whicli tbe endosarcal cord passed from 

 cell to cell. These were tbroo in number on tbo side walls, and they
