streams, up the trunks of which they crawl to the height of six to 

 eight feet from the ground. They seem to have found by expe- 

 rience that this is the only way of securing safety from the 

 extensive floods which are so frequent at Oxford during the colder 

 months of the year. 



Succinea elegans, Risso. — By ditches in several places ; near 

 Marston Ferry, near Watereaton, by the stream in Wick Copse, 

 and near Eynsham Bridge. 



Vitrina pellucida, Muller. — Rather common ; in shady woods, 

 and on hedge-banks amongst moss and dead leaves and under 

 stones. It is active and very hardy : I have seen it crawling about 

 when snow was on the ground during the commencement of a 

 thaw which succeeded a severe frost, in January, 1881. It is 

 found, indeed, more frequently alive in the winter months, from 

 November till February, after which date the number of living 

 individuals seems to dwindle, till in summer it is difficult to 

 find any. 



Zonites cellarius, Muller. — Abundant in damp places every- 

 where. 



Var. albida. — Occasionally found with the ordinary form; 

 Wytham Hill, and near Islip. 



Z. alliarius, Muller.— Rather plentiful under stones, especially 

 on limestone soils. 



Z. glaber, Studer. — Rare. I first took it very sparingly under 

 stones lying about the borders of Wick Copse, and subsequently 

 a few specimens from near Woodeaton. 



Z.nitidulus, D rap. — Very abundant; burrows under loose earth. 



Var. nitens.— In quarry of Portland sand on Shotover Hill, 

 under loose stones. 



Z. purus, Alder. — Rare. I have only found it amongst moss 

 and dead leaves in Powder Wood, near Cumnor Hurst. 



Z. radiatulus, Alder. — Not plentiful ; in moist shady places 

 and woods ; Wick Copse, wood near Childsworth Farm, and 

 Powder Wood. 



Z. nitidus, Muller. — Plentiful on the marshy meadow land 

 about Oxford, along canal and ditch banks. 



Z. crystallinus, Muller. — Abundant in damp places. 



Z.fulvus, Muller. — Not uncommon in woods and copses, both 

 in dry and wet places. Specimens taken from a dry locality are 

 generally of larger size and paler colour.
