EXHIBITIONS. 
Mr H. Coates exhibited the following:— 
1. A specimen of the Snail-slug (Testacella haliotidea, 
Drap. var. scutulum). This interesting slug was forwarded 
to Mr Coates by Mr W. D. Sang, C.E., Kirkcaldy, who 
found it in the St Brycedale Nurseries, in that neighbour¬ 
hood. This was the first time the species, or indeed the 
genus, had been reported as a native of Scotland, its most 
northerly habitats previously known to zoologists being 
Yorkshire and North Durham. It is common in France 
and Southern Europe, and in England is found chiefly in 
the southern counties. It has been known to Mr Sang to 
occur in the St Brycedale Nurseries for six or eight years; 
so that if, as is probable, it was accidentally introduced 
with nursery plants, it has now thoroughly established 
itself in the locality. It frequents the boxwood borders, 
and is very seldom to be seen, except in early morning 
during wet weather in spring and autumn. The specimen 
had been verified by Mr W. Denison Roebuck, of 
Leeds, the leading authority on slugs. Mr Coates then 
pointed out some of the remarkable peculiarities of struc¬ 
ture and habit which distinguish this from all other genera 
of slugs. It lives chiefly on earthworms, which it pursues 
through their burrows. Its shape is specially adapted for 
this, being long and worm-like itself, and its breathing 
organs are situated at the extremity of the tail, and 
covered by a flat external shell to protect them from 
injury in crawling through the burrows. Its tseth also are 
strong and recurved, to enable it to seize and hold its prey. 
2. A fractured shell of the common banded snail (Helix 
nemoraUs), which had been repaired by the mollusk in a 
remarkable way. Shells that have been damaged and re¬ 
paired are of frequent occurrence, but the peculiarity of 
this specimen consisted in the last whorl having been 
entirely displaced, so as to present the appearance of one 
shell growing within another, though it had been mended 
in such a way that the inside of the shell presented an even 
surface. The specimen was found at Invergowrie during 
one of the excursions of the Society last summer. 
3. Contorted specimen of the fresh-water coil-shell 
(Planorbis vortex), from Errol. This is normally a 
perfectly flat coiled shell, but in the specimen exhibited
