THE COPEPODA OF LIVERPOOL BAY. 65 
Pontella wollastont, Lubbock. 
This species, with the last, was referred to specially in 
a recent paper (Proc. L’pool Biol. Soc., vol. I., Pl. VI.) as 
having been found during the ‘‘ Weathercock”’ expedition, 
the only previous record of its occurrence near Britain 
being by Sir John Lubbock, who took it at Weymouth in 
1857. It has since occurred during the past summer in 
several gatherings taken around Puffin Island. 
Parapontella brevicornis, Lubbock. 
Found sparingly in the open sea, and more recently 
around Puffin Island. 
Isias clavipes, Boeck. 
Taken on several occasions in the open sea some miles 
from land. Neither Boeck nor Brady notice a pair of 
remarkable trifid spines which occur one on each side of 
the first abdominal somite of the female.

Thorellia brunnea, Boeck. 
Found very sparingly in the open sea.

Both of these species of Cyclopina have been found in 
recent tow-net gatherings about Puffin Island.
