a ambigua, u.s. Lochgelly Loch, not common. 
Liyocypris gibba (Ramdohr). Lochgelly and Raith Lake. 
_ Limnicythere inopinata, Baird. Occurred in the three lochs. 
Candona ambigua, provisional name (Pl. LV. figs. 7a-c). Shell.—Lateral 
view somewhat similar to C. pubescens, but the straight part of the dorsal 
margin is more central, and the slope from each end of it towards the ex- 
tremities of the shell more equal than in that species. The flexure of the 
ventral margin is also more distinct. Height rather more than half the 
length. The outline as seen from above is very compressed, much more 
so than in C. pubescens. It is acuminate in front and narrowly rounded 
behind. Wdedth a third of the length. Length, 5 in.=°83 mm.; height 
sg in. Antennules.—The length of the first, second, and fourth joints 
counting from the extremity is nearly equal, the third is about two-thirds the 
length of the second, the fifth is about equal to the third joint. Antenne. 
—The ultimate scarcely half the length of the penultimate joint, which is 
about two-thirds the length of the preceding. I could not clearly make 
out the other joints of the antennules and antennze in my dissections. 
The figures show approximately the proportional lengths of the joints.

3. Loca Ness, Loc Oicu, anp Loca Locuy. 
These lochs occupy a considerable portion of the great valley that 
stretches across Scotland from the Moray Firth to Loch Linnhe, and they 
constitute about two-thirds of the entire length of the Caledonian Canal, 
_ the whole length of which is about 60 miles, while the combined length of 
the three lochs is little, if anything, under 40 miles. 
For various reasons it was considered desirable that an effort should be 
made to examine the invertebrate fauna of these lochs while the ‘Garland’ 
was proceeding through the canal on its way to and from the west coast, 
but the stormy weather encountered by us, both going and returning, 
formed a serious hindrance to anything like a satisfactory investigation 
being made.
