COPEPODA OF MADEIRA AND THE CANARY ISLANDS.

Even after becoming acquainted with this artful dodge, the bare 
must be stalked with caution. Being all white except the tips 
of its ears, it is not easily seen when nearly buried in the snow, 
and when discovered the sportsman must dissemble, and pretend 
that he has not seen it, walking in an oblique direction, ap- 
proaching, but at the same time as if passing by, never looking 
directly at the game. When near enough he should wheel 
suddenly round and fire. If this plan be not adopted, the hare 
will very generally bolt round the rock, and escape under its 
shelter. This may be called pot shooting, but the best of sports- 
men have often to do the same thing with ptarmigan in the 
Scottish mountains, when these birds fly round a rock and are 
out of sight in an instant, if not shot before taking wing. 
Copepoda of Madeira and the Canary Islands, with Descriptions 
of Hew Genera and Species. By Isaac C. Thompson, 
F.R.M.S. (Communicated by Prof. Herdman, E.L.S.) 
[Read 17tk November, 1887.] 
(Plates X.-XIII.) 
During the spring of 1887, in company with Mr. W. S. M‘Millan, 
of Liverpool, I visited Madeira and the Canary Islands with the 
object of collecting and examining the pelagic fauna at the 
various convenient stopping-places. 
We took dredge and tow-net, and all the necessary appliances 
for the examination and preservation of specimens, and were for- 
tunate in securing a large mass of material. 
It is intended in this paper to treat of the Copepoda only ; and 
as the dredging operations w T ere neither so practicable, nor fruitful 
in results as the tow-netting, it was to the latter that we de- 
voted chief attention, all the Copepoda collected being free- 
swimming species. 
We used one of the very fine-meshed tow-nets of the ‘ Chal- 
lenger ’ pattern, and immediately preserved the captures in a 
medium which I have always found useful for small Crustacea, 
composed of glycerine, alcohol, and water in the following pro- 
portions : — 
Glycerine 1 part ] 
Proof-spirit... 2 parts L adding 1 per cent, of carbolic acid. 
Water 1 part J
