177 LAND AND FRESH-WATER MOLLUSCA OF BUTE. 
specimen of Helix rufescens at Ettrick Bay, but I did — 
not observe this mollusc here or elsewhere within 
the area examined. | 
When at Ettrick Bay I had a hunt round for the 
Horned Poppy (Glauciwm luteum) which used to | 
grow by the side of a little burn that runs into the 
bay, but failed to find it. I hope that it has not 
become extinct. . 
St. Ninians District. 
Helix ericetorum, which Haddin recorded as having” 
been observed here, still exists, but apparently is not — 
very common. With this exception, all the molluses 
observed about St. Ninians Bay were common species. 
Ascog and Kerrykroy District. 
The only place where I observed Planorbis spirorbis — 
was in a pond above Ascog Bay; and in the wood 
by the shore, near the entrance to the old coal-mine, 
I got the curious little Helix aculeata, as well as 
Vertigo edentula. Some of the commoner molluscs, 
such as Pupa wmbilicata, were plentiful in this 
district. Haddin records finding Pupa ringens in ~ 
Mountstuart Wood; but I did not observe this 
species in any of the localities examined, and have 
included it in the list on his authority. | 
I have now made a general though hasty refer- | 
ence to the more or less noteworthy molluscs found 
within the area described. A full list follows of all 
the species known to occur in Bute, including those 
recorded by Haddin but which I failed to observe. 
A map is appended of the portion of Bute specially 
referred to in this paper.
