allowing itself unresistingly to be pushed to the side with a hair 

 pencil. The young, when viewed from above, are more compressed 

 posteriorly than the adult; at this stage the dark bands are absent 

 or nearly so.

Found in a small creek of Lochlomond at Luss; in a small 

 pond near Banff; in Frankfield Loch, near Glasgow; in Loch Libo, 

 near Dairy ; in Full wood, Hairlaw, and Craiglaw Dams ; in all 

 moderately rare. Also in a number of the ponds along the shores 

 of Cumbrae, subject to the spray of the sea. Moderately common 

 in the Isles of Skye and Lewis. Common in lochs of Lochmaben. 

 This species appears to be more a mud than a plant dweller. The 

 young have few or no hairs on the carapace, and are much 

 smaller, posteriorly, than the adult.

Frequents water more or less brackish. It was abundant in a 

 pool at Ferry House, Cumbrae, now filled up. This pond was

 the sea during storms and high tides. Also in brackish pools 

 along the shores of the south-west end of Cumbrae. Isle of Skye. 

 When confined they cluster together on bits of floating alga?, 

 appearing like batches of small mussels.
