64 LIVERPOOL BIOLOGICAL SOCIETY. 
a dark cold night, the tow-netting from Puffin Island 
consisted of quantities of Tomopteris and Sagitta, with 
only a few Copepoda. It is, however, noticeable that with 
the exception of Trebwus caudatus (referred to later) the 
night collections have hitherto been little different from 
those of the day. During the early spring of the present 
year, I noticed on several occasions large quantities of 
diatomaceous matter floating near the surface of the 
sea, but it disappeared about May, and there has been 
no observation of the gelatinous Algse referred to in last 
Report about our coasts. 
The thirty-one species recorded since the last Report 
are as follows :— 
FAMILY CALANIDZ. 
Paracalanus parvus, Claus. 
This rare form, described by Claus in his work on the 
marine Copepoda of Trieste, was taken by tow-net near 
Puffin Island, in September, in the ‘‘ Gamecock”’ expedition. 
Dias discaudatus, Giesbrecht. 
Taken off the Anglesey coast by tow-net on the ‘‘ Hyzena”’ 
expedition. 
Temora velox, Lilljeborg. 
This brackish water species is probably somewhat 
common in the district about salt marshes. Mr. W. 8. 
McMillan found it as far inland as Sefton, and we recently 
together found it plentiful in the long narrow pools 
immediately behind the Leasowe breakwater. 
Eurytemora hirundo, Giesbrecht. 
This rare form, hitherto unknown to Britain, was found 
in two early morning gatherings, tow-netted by Mr. Clubb, 
in the Crosby Channel, and was referred to at length in a 
paper read before the Biological Society last session.
