MR. A. MAYFIELD ON NORFOLK SLUGS. 
407 
Limax maximus, L. Fairly common. Upon a Hint wall at 
Kirby Bedon. In outhouses, Heigham. I have taken several 
specimens at different times from the brickwork at the north gate of 
Norwich Cemetery. 
Limax flavus, L. In cellars, beneath rain-water tubs, and 
among rubbish in gardens, Norwich. 
Limax marginatus (Miill.) = (L. arborum, B-Ch.). Several 
small specimens under moss on willows at Eaton and Lakenham. 
A single one upon the railway bridge near Dunstan. Two light 
coloured specimens at the base of a beech-tree at Backheath. 
Agriolimax agrestis, L. Very common everywhere, varying in 
colour from pure white to brown and dark gTey. 
Agriolimax l.evis, Mull. Upon sedges and flags by river 
side at Bramerton Common, Costessey, Kingland, Colney, and 
Cringloford. 
Testacella haliotidea, Drap. Some specimens of Testacella, 
collected at Aylsham by Rev. S. Spencer Pearce, were forwarded to 
Dr. Heinrich Simroth, of Leipzig, for identification ; he said in 
reply : “ The dissections showed undoubtedly that all were 
Testacella ha/iotiilea ” (‘Journal of Conchology,’ vol. vi. p. 423). 
1 have never met with any Testacella near Norwich, and I should 
like to know if any one has found specimens lately upon the 
Ipswich road. 
Testacella scutulum, Shy., which is now considered specifically 
distinct from the preceding species, has been recorded for East and 
West Norfolk in the Conchological Society’s “Census of the 
Distribution of British Land and Fresh-water Mollusca.” 
It will be seen from the above list that my records are confined 
to the Norwich district. For any one with time and inclination to 
attempt to enlarge the Norfolk list, the Broad district ought to 
prove a happy hunting-ground. Not only might other species be 
found, but a great deal of information might be gained as regards 
the colour-variation of those species already recorded.
