species is of a cream-colour or a dirty white. In a ditch at Rowan 

 Bridge, on the side of Glasgow and Paisley Canal, the greater 

 number were greenish. In Govan Colliery Old Dam they had all 

 a fine reddish tinge, as was also the case at Craiglockhart Curling 

 Pond, near Edinburgh.

Moderately common amongst muddy roots of vegetation and 

 bottom mud. In Loch Libo and Johnstone Loch, rather common, 

 but in poor condition. Common in an old ferruginous limestone 

 quarry, Hairmyres. Abundant in an upper reach of a mill-dam 

 at Cadder Wilderness, where the water does not all draw off; the 

 bottom was all soft black mud with a little weed and conferva?, and 

 many decaying leaves from overhanging trees; the water did little 

 more than cover the mud, all having a very unclean aspect. 

 Common on Upper Braid Farm Loch, near Edinburgh. In this 

 patch of water the shells of many were so soft and flexible that 

 they were more or less corrugated or dimpled. Very fine and well 

 marked in Pendreich Dam, Bridge of Allan. 



This species is closely allied to Cypris compressa, but rather 

 larger, and generally of a darker purplish colour, and less shining. 

 It is readily distinguished by the fine striae on the shell, yet in 

 some cases this is only seen under a good microscope. It comes 

 still more closely to Cypris granulata, sjj. nov., which is smaller 

 and paler in colour,

Frequent in ponds and ditches, and occasionally in brackish 

 water; chiefly in the mud at the bottom, and sometimes under 

 varied circumstances. Generally in pure water, but also where it 

 is quite otherwise. In a gathering at the Port-Eglinton Terminus, 

 of the Glasgow and Paisley Canal, they were common where the 

 water was covered with floating oil from the refuse of neighbouring 

 factories, and the mud from which they were dredged was of the
