Mr. Waring tons Aquarium. 3381 



Cyclas flavescens, Mac Gill. Common ; in the Loch of Skene, ten 

 miles to the west of Aberdeen. 



Pisidium Jenynsii. Common in all clear stagnant water, both in 

 pools and ditches. 



„ pnlchellum. Common in muddy and sandy pools and 

 ditches ; and most beautiful specimens occur among Sphagna in pools 

 of water among the hills. 



j, nitidum. More rare, but occurring with the last, 

 „ pusillum. Abundant in many places, as in a mill-pond 

 near the new bridge of Don. 



„ amnicum. Rare. In the canal and the Hilton quarries, 

 Mr. Clark. 



Anodon anatinus. Common ; in the St. Fergus canal, Banff. 

 Alasmodon margaritiferus. Common in the Dee and the Don, and 

 discovered in great plenty in the burn of Canry, at Upper Banchory, 

 by Mr. Ewan. 



All the above have been seen by myself during the last two or three 

 years, and all occur in Aberdeen and Kincardine shires, with the ex- 

 ception of Anodon anatinus, which as yet is only found in Banffshire. 

 In conclusion I may mention that Zonites pygmaeus, Planorbis im- 

 bricatus, Paludina vivipara and Bithinia tentaculata have been found 

 here, but not alive, and consequently are not included in the list.

My dear Sir, 



In recapitulating my experiments of 1849 and 1850 * in January, 

 1852,-f I stated that I was carrying out a similar investigation, in the small aquarium, 

 with a confined portion of sea-water, employing some of the green sea-weeds as the 

 vegetable members of the series, and the common winkle or whelk to represent the 

 snail as a scavenger; and in September, 1852,;}: I mentioned that I had succeeded per- 

 fectly in my endeavours, having had the sea-water quite clear and sweet for upwards 

 of six months, and had for some time maintained the healthy life of several sea anemo-
