Valvata piscinalis var. antiqua Sow. Mr. A. S. Kennard 
informs me that the true variety antiqua Sow. is extinct in 
this country, and that in his opinion the Gloucester form should 
be called V. piscinalis var. obtusa [= presumably V. obtusa, 
Brard]. 
Sphaerium corneum var. pisidioides, Gray. Mr. 
Kennard is also of opinion that this is wrongly named, and 
that the form is very near to shells which were identified by 
Dr. Johansen as S. corneum var. firmum, Westerlund. 
Additions and Observations. 
zonitid;e. 
Vitrea lucida, (Draparnaud) [ = draparnaldi Beck]. 
Mr. A. S. Kennard informs me that this species occurs at Clifton, 
and that he has it from that locality. This should therefore 
be included in the county list. 
HELICID/E. 
Helicella cantiana (Montagu). Although this species is 
common in many parts of the country, it is by no means 
abundant in Gloucestershire. A hitherto unrecorded habitat is 
therefore of interest. During the past autumn I found it quite 
plentiful by the side of the road from Withington to Cassey 
Compton. The coloured parts of the shells were more than 
usually pink. 
Helix nemoralis, L. During the autumn of last year I 
found a considerable colony by the side of the Gloucester and 
Berkeley Canal near Ouedgeley having a somewhat uncommon 
band formula. The molluscs were quite numerous for a 
distance of perhaps one hundred yards along the canal bank, 
but in a large proportion the three upper colour bands were 
wanting, whereas the two which occur on the under side of 
the shell were present. 
Another interesting colony occurred by the canal side near 
the boat-house at Hempstead. In this case the shells were all 
ordinary five-banded forms, but considerably larger than usual.
