NOTES ON SOME RARE COPEPODA FROM SCOTLAND 233 



cealed themselves under the banks, and we did not desire to 

 disturb them after identification was complete. On the 

 fourth loch visited we saw a brood of six young Wigeon 

 and several old birds, in addition to other wild-fowl. All 

 the young Wigeon seen appeared to be of the same age, 

 which we estimated at ten days. A conspicuous and un- 

 varying feature in the ducks with broods was an extreme 

 solicitude for their young. They kept flying round our 

 party, often within easy gunshot, uttering their peculiar 

 croak, so long as we intruders remained in the neighbour- 

 hood of their progeny. Following Mr. Evans's example, of 

 which I approve, I do not think it judicious to be more 

 specific as to locality. 



I believe that this is the first occasion on which the 

 breeding of the Wigeon, in a wild state, has been reported, 

 with proofs, south of the Forth.

ONE of the Authors of the following Notes, in a paper 

 recently published in the " Annals of Scottish Natural 

 History," refers very briefly to the recent discovery of two 

 freshwater Copepods in Loch Leven, Kinross-shire, that have 

 not previously been recorded as members of the British 

 fauna. Though both species have been described in con- 

 tinental works, we do not know of any description of them 

 in English, and have therefore prepared, and now submit, 

 the following descriptions, with illustrative drawings, based 

 upon specimens obtained in Loch Leven. We also take 

 this opportunity to record some observations on the habits
