NOTES ON sUCCINEA OBLONGA, DRAP., 
AND OTHER SPECIES AT oe,

On Good Friday, March 29th, a small party spent the day in 
hunting for shells in this favourite locality. The weather was 
‘magnificent, the temperature being more like July than March. 
Our main efforts were devoted to ascertaining the distribution 
of Succinea oblonga, taken for the first time, in August last year, 
by Mr. H. Beeston of Havant (‘ Naturalist,’ Jan., 1907, p. 31). 
Our first efforts were, however, disappointing, and we decided 
to try fresh ground some little distance away from the ditch 
where Mr. Beeston discovered his specimens. In this we were 
more successful, and were soon rewarded by finding a dead adult 
specimen. This was shortly followed by others, among which 
were a few full-grown living ones. We then became aware 
that the sides and bottom of the damp ditches in which we were 
working contained numbers of juvenile examples, all on the 
crawl, along with a number of other species. 
We were surprised to keep coming across numbers of dead 
slugs, chiefly Agrzolimax agrestis and A. levis, which had the 
appearance of having been drowned—no doubt during the 
recent floods, when many of the marshes in this district were 
covered by the heavy tide. The animals were mostly in an 
extended condition, and some were covered with a whitish mould. 
The other species of mollusca noticed living in the ditches and 
their vicinity were Hygromia hispida, fine specimens and very 
hispid ; Succinea elegans, a few juvenile examples ; Carychium 
minimum, abundant ; Punctum pygmeum ; Cochlicopa lubrica ; 
Agriolimax agrestis, A. levis; Arion ctrcumscriptus ; Limnea 
pereger var. maritima, L. truncatula,; Aplecta hypnorum ; 
Pisidium pusillum, and P. obtusatle. 
‘Crossing over out of Westmorland to the Lancashire side oe 
the river Winster, we made our way back to Grange, examining 
other likely habitats for S. oblonga on the way. Near to a 
triangular piece of brackish water and marshy bit of ground we 
were surprised to find the species again in evidence (all young 
specimens) at the roots of grass on the top of a low wall—a 
most unusual habitat for Succtnee. Flood work was again 
noticeable, and numbers of dead land shells were strewn
