ON FOSSIL POLYZOA. 103 



One of the two British recent examples is M. Jeffreysii, Norman, and of 

 this minute fragments only were obtained in the Shetland dredsrino-s 

 by Mr. Jeffreys and Mr. Norman, particulars of which are given in 

 former reports by these authors.

The fragments found in the Garvel Park beds are very minute. 'Cat.

The identification of fossil Scrupocellaria is difficult, because, the
