Genus BEEOE. 

 Beroe Ovata. 



Irregular in the time of its appearance, but sometimes as early as " Cydippe 

 Pileus." 



Genus NOCTILUCA. 



NOCTILUCA MiLIAEIS. 



In the Mersey in myriads. It is this species chiefly which imparts a phos- 

 phorescent appearance to the water at nights, as may be proved at any time 

 by taking some of the river water containing them into a perfectly dark 

 room, and splashing it about with any hard body to irritate them. They 

 may be seen as little hyaline-globules about the size of a pin's head. Three 

 or foiir years ago, in company ■n'ith Mr. Price, we saw millions of them 

 coUeeted together at Hilbre Island, in a little pool, when they tinged a 

 portion of the water, about two yards in circumference, with a deep pink 

 colour. The individuals in this collection were of a light pink hue under 

 the microscope; those from the river are colourless. The men upon the 

 fen-y steamers state that the phosphorescent appearance of the water is 

 much more noticed some years than others. They associate its presence 

 with southwardly winds.
