SOME COPEPODA NEW TO BRITAIN. 35 
and it was the only species of the genus we had recorded. 
But in April, 1886, two bottles were sent to me by Mr. 
Clubb, containing the surface gatherings of two night and 
early morning tow-nettings, obtained from a fishing boat in 
the Crosby Channel, and between Formby and Southport. 
Temora longicornis was present in large quantities, and with 
it a number of another species not previously observed 
here. Upon looking up the literature of the subject, 
this species was found to be Hurytemora hirundo of 
Giesbrecht, described and figured by him in “Die 
freilebenden Copepoden der Kieler Foehrde,”’ and found by 
him only in the Ostsee (Baltic). It occurs in the material 
collected by Mr. Clubb on two separate days, the 9th and 
23rd of April, both from the Crosby Channel, at night, 
but we have not taken it before or since, or in any other 
locality, nor has it been elsewhere recorded by any one 
except Giesbrecht. 
Giesbrecht proposes to divide the genus Temora of Baird 
into two sub-genera, Halitemora and Eurytemora, as 
follows, the characters of the two divisions being suf- 
ficiently distinct to warrant it.

The Halitemora longicornis and H. velox are the only 
hitherto known British species of Temora, to which is 
now added Hurytemora hirundo (P1. IV., fig. 1). 
Males and females were found in about equal quantities; 
the right antenna of the male (fig. 2), and the difference 
in the first pair of swimming feet, as shown in figs. 3 and 4
