leaves of ^%•hich may be found the curious polyzoou 

 Cristatella miwedo, and the equally interesting and 

 prettj' entoniostracan 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 Avith the summers 

 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 may 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 Planorhis glaher^ 

 Jeffreys {P. parvus, Say), which occurred at the 

 lower end of the loch, and was not unfrequent. 



Kames 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 pidchella, H. 

 pygjncea, 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 H. 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
