 On Flustra truncata and Plumularia Cathenna, from the 

 coralline zone, Cullercoats. — J. A. 

 This species is of an opaque ochi-e-yellow colour when fresh, 

 but changes to a blackish brown by exposure to the air. The 

 name oifiisca does not, therefore, well characterise it in its living 

 state. The tentacles (20 in number) have an opaque white line 

 down the centre.

Johns. Brit. Zooph., 382, t. Ixx., f. 5. 

 On small sea-weeds and corallines, near low-water mark; 

 frequent. 

 A minute Pedicellina with a smooth stem, apparently distinct 

 from this, was observed on a stone from a tide-pool at Culler- 

 coats. It is probably the P. gixicilis of Sars, but from its 

 position and small size, its characters could not be distinctly 

 ascertained.
