Figures 3 and 4 show an organism which is less 

 commonly met with here. In this form the outer rim 

 curves upwards, and we have never seen more than one 

 protoplasmic body in the centre. The central cavity, 

 containing the oval-shaped protoplasmic body, is some- 

 what like a spinning-top with a bluntly rounded point. 

 This form appears to be the organism described by Cleve 

 as Pacillina {Fungella) arctica, from plankton collected 



by the Swedish Expedition to Spitzbergen in 1898. It 

 has also been recorded from the North Sea, the Skagerrak 

 and the Kattegat. A form described by Vanhoifen under 

 the name " Chinesenhut " closely resembles Cleve's 

 Pacillina, but differs in the outer rim being turned down- 

 wards and in having the produced part of the capsule 

 containing the protoplasmic body quite pointed.
