COPEPODA OF MADEIRA AND TUE CANARY ISLANDS. 145 



Even after becoming acquainted with this artful dodge, the hare 

 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 New Genera and Species. By Isaac C. Thompson, 

 r.E.M.S. (Communicated by Prof. Herdman, E.L.S.) 



[Read 17th November, 1887.] 

 (Plates X,-XIII.) 



During the spring of 1887, in company with Mr. W. S. McMillan, 

 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 were 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 : — 



Griycerine 1 part 



Proof-spirit... 2 parts I adding 1 per cent, of carbolic acid. 

 "Water 1 part J
