BATHYMETRICAL SURVEY OF 
The few species which only occurred in some of the lochs are noted 
below. These are also generally distributed in summer, their scarcity 
in these lochs being due to the late season at which they were visited.

variety galeata, a large form with the head angled. 
Holo'pedium gihheruni . — Only in Lochs Calavie and an Tachdaidh. 
Leptodora kindtii . — Only in Loch Monar. 
Polyphemus pediculus . — ^An Gead Loch. 
Cyclops strenuus . — Present in most of the lochs. The Cyclops in 
Loch Calavie were red-spotted.

Floscularia pelagica. — Loch Monar.

attached to the sounding-rod, from depths of 6 or 8 feet, in Loch a’
