11. Helix imlchella^ or pretty Helix, is consider¬ 
ably larger than the pygmoeo, shell flattened, glossy, 
and of a light grey colour. The name seems to have 
been given on account of the beautiful shape of the 
shell—the mouth being circular, and the outer lip 
very thick and strongly reflected, forming a ring, 
gives it the appearance of a fairy trumpet. The shell 
is found among dead leaves, and under stones and 
logs of wood, and has been met with on both KinnouU 
and Moncreifi'e Hills, and is no doubt common 
throughout the county. 
Such are the shells of the genus Helix, eleven in 
number, which we have yet been able to discover in 
Perthshire. There are strong reasons, however, to 
believe in the existence of Helix caperata in the dis¬ 
trict. This shell, which is about the size and form 
of H. liispida, of a greyish white colour, and marked 
with yellowish brown bands, is very abundant in 
Forfarshire along the|sands of Barry, and not being 
confined to maritime districts, it is likely to occur in 
dry and sandy soils inland. Specimens of a shell 
have been picked up on a dry bank at Quarrymill 
with some appearance of markings similar to H. 
coperota, but as the animal has never been found 
-alive, they are probablv rubbed and bleached shells 
biLQ jri , ti'ispiacL OT izL concinna. The locality is a pos¬ 
sible one, however, for the shell; and farther research 
will, in all likelihood, prove its existence. Another 
shell, ^ the Helix ericetorum^ will probably be met 
with in the course of our investigations. It is found 
in the neighbouring county of Fife, and there is no 
reason why it should not occur here. Still another 
shell may turn up in the county belonging to the 
genus ^namely, Helix lamellata. It is common to 
the north and west of Scotland and to the north of 
England, and it may be found in Perthshire. 
Mr J. Allen Harker read a paper on the 
British Hyjmphjeacea or Water Lilies, 
the three members of which are found in the county. 
The principal portion of the paper was devoted 
to an examination into the claim of Nuplutr 
pumila to be considered a distinct and well-
