description in the hope of finding more specimens. Still 
more recently I have found in the shells of the Pecten 
maximus a large Lichomolgus herein described as Licho- 
molgus maximus. It is probable that the examination of 
other mollusca obtained when dredging may lead to the 
discovery of further new species of parasitic Copepoda. 
A closely allied species to the two last mentioned, Sabel- 
liphilus sarsit, Claparéde, was sent to me by Mr. Chadwick, 
adherent to the tentacles of a species of Sabella collected 
on the Beaumaris shore. Ihave since found it attached 
to the same host around Puffin Island and think it 
probable that although apparently hitherto unrecorded 
elsewhere in British waters, 1t only requires looking for. 
As a preservative fluid for Copepoda I have always 
found a mixture composed of equai parts of Alcohol, 
Water and Glycerine with 1 per cent. of Carbolic Acid 
most useful. Specimens may be transferred direct to it 
from sea water and can be so preserved for any desired 
period of time, to be mounted direct without further pre- 
paration in either Glycerine Jelly or Farrants Medium. 
I can confirm the value of Canon Norman’s “ excellent 
device’ for capturing Copepoda and other small Crustacea 
while alive from freshly dredged material as given by 
Mr. A. O. Walker, F.L.S. (Report on the Higher Crus- 
tacea of Liverpool Bay taken in 1889) Fauna of Liverpool 
Bay, Report III, p. 239, 1892, many rare Copepoda 
having come to me through this means. Recently I have 
employed a still more exhaustive method with the greatest 
advantage, particularly when as is often the case material 
or dredged mud or sand requires to be kept a considerable 
time before it can be examined, viz., the dredged material 
is washed through a coarse sieve into a finely meshed 
silk bag into which a running stream of water from a tap 
is allowed to fall. By careful kneading with the hands
