ZOOLOGY 
MOLLUSCS 
Although there are but few published lists for this county, so well 
has Capt. Farrer in especial worked the district’ that no less than 93 
species have been recorded out of a total of 139 for the whole of the 
British Islands. 
One other species, the scarce and local Vertigo moulinsiana, was 
chronicled but subsequently withdrawn by Capt. Farrer as wanting con- 
firmation, though since it occurs quite as far north in Ireland, there is no 
inherent improbability in its also living in the Lake district. 
No southern species is of course to be met with, and though Capt. 
Farrer tried to establish a colony of He/ice/la cantiana near Bassenthwaite, 
the experiment did not succeed. A colony of Helix /ucorum from Italy, 
on the other hand, has thriven. 
Several northern forms, such as Acanthinula lamellata and Unio 
margaritifer, are present. 
The common garden snail (He/ix aspersa) is curiously scarce in the 
county as a whole, especially in the inland parts, and some common fresh- 
water forms, like Limnaa auricularia, L. stagnalis, Planorbis corneus, and 
both species of Vivipara, are absent altogether.
