Kaith Lake. 
Eaith Lake, in the parish of Abbotshall, is situated within the pleasure 
grounds of the Raith estate, the property of Munro-Ferguson, Esq. M.P. 
and is therefore private. Permission to examine the loch was readily- 
granted to me by Mr Prentiss, factor on the estate, who also kindly 
offered to give me the use of a boat, but unfortunately I was unable to 
take advantage of it for want of time. The site of the loch was 
originally an extensive hollow, as if scooped out in some measure for the 
purpose by the hand of Nature, and by filling the hollow up at some 
places, and deepening and extending it at others, the formation of the lake 
was in a short time completed. The extent of ground covered by it is not 
less than 21 acres, and the water is in some places 25 feet deep.* Trout, 
Perch, Pike, and Eels are common in the loch. It is beautifully situated, 
and is to some extent surrounded by trees and shrubbery ; in some places 
it is partly overgrown with vegetation, and the Bull-rush [Typha LatifoUa)^ 
a rare plant, grows luxuriantly at its lower end. At the time of my visit 
the water was teeming with Entomostraca, some of the more common 
species being Sida crystallina, Daphnella brachyiira, Scapholeberis 
rornuta, Pleuroxus uncinatus. A great variety of Cladocera were obtained 
here. Copepoda were also common, and included Cyclops affinis and what 
appears to be an undescribed species. Ostracoda were scarcely so numerous 
as might have been expected. MoUusca were moderately common, but 
the species obtained belonged to those that are of more or less general 
occurrence throughout Scotland. The curious Diatom, Gomphonema 
ca'pitatum, Ehr., was obtained here. 
Camilla Loch. 
Camilla Loch, in the parish of Auchtertool, derives its name from the 
old house of Camilla, anciently called Hallyards, but which was changed 
to Camilla from its being the residence of one of the Countesses of Moray 
whose name was Campbell. The loch is situated a little to the north of 
the village of Auchtertool. The extent of its surface is about 18 acres, 
and its greatest depth is said to be 22 feet, the deepest part being towards 
the east end. The west end is much overgrown with vegetation. It con- 
tains perch, pike, and eels. The small stream that runs from the loch 
is the principal feeder of Raith Lake. 
The invertebrate fauna of the loch appeared to be fairly abundant, but 
there was time for only a partial examination being made. Among the 
organisms collected, Entomostraca were largely represented. In some of 
the small sheltered bays, where the Avater was shallow, the common Cyijria 
serena were observed swimming about in myriads. The Horse Leech, 
{HcBmopsis vorax, Mog.), was common in the soft mud at the west end, 
where the water was shallow. Among the Cladocera observed were Alona 
guttata and the somewhat rare Alona tenuicauda. The beautiful Volvox 
globator was also observed in this loch. 
LOCHGBLLY LoCH. 
This loch, also in the parish of Auchtertool and a short distance north- 
west of Camilla Loch, is about three miles in circumference, and is much 
overgrown with vegetation along the south side. Part of this side only
