THE FRESH- WATER LOCHS OF SCOTLAND. 147 



quite choked with animals. A single dip of the net, by which about 

 half a gallon of water would be strained, collected enough material to 

 fill a 2-oz. bottle. The Daphnia was of two forms, one small and the 

 other much larger than usual, and 'many males were seen. There was 

 little else in the loch, only Diaptomus (hyaline) and a species of 

 Aiiabcena being at all plentiful. 



Monk Myre. Notholca longispina formed a " Wasserblut " here, 

 giving the collection a reddish colour. Diaptomus (grey or hyaline), 

 Bosmina cornuta, and Polyphemus were common.
