leaves of which may be found the curious polyzoon 
Cristatella mucedo, and the equally interesting and. 
pretty entomostracan Sida crystallina. Here Hydra 
vulgaris also luxuriates, and many other strange- 
looking organisms. This end is so shallow, and dries 
up so much, that in some places it may be crossed 
on foot. There is so much decaying vegetation that 
the water, as it becomes warmed with the summer's 
sun, is found to be literally teeming with minute 
forms of life, and no doubt forms a “happy hunting- 
ground” for the micro-zoologist who aly happen to_ 
find his way to the spot. 
I found comparatively few terrestrial molluscs 
about this loch; and although aquatic forms were 
numerous enough, those observed belonged to com- 
mon species, with the exception of Planorbis glaber, 
Jeffreys (P. parvus, Say), which occurred at the 
lower end of the loch, and was not unfrequent. 
Ksames Bay District. 
The promontory on the opposite side of the bay 
from Port Bannatyne is known as Undranian Point, 
and there are here what appear to be the ruins of 
a limekiln. Under the loose stones which lie scat- 
tered about were observed Helix wulchella, H. 
pygmea, Zonites radiatula, and several common 
species. By the side of a wall a short distance north 
from the Hydropathic Establishment, and at the side 
of an old inland road which joins the road to Ettrick 
Bay, a short distance to the west of the head of 
Kames Bay, were found Helix aspersa var. conoidea 
and Hf. hispida var. alba; while, by the side of a 
small rivulet above Skeoch Wood, Zonites nitidus 
was of somewhat frequent occurrence. 
Ettrick Bay District. 
The species observed here were chiefly common 
ones, the only forms calling for special notice being 
Helix caperata, H. pulchella, and a very small variety 
of Clausilia rugosa. Haddin records finding one
