This is our largest and rarest species of Vertigo. Its 
variety /i/jeborgiz was first discovered in Co. Galway by 
the late Dr. Jeffreys in 1845; and it has also been found 
in the Aran Islands by Dr. Scharff. In England the type 
has been noted among rejectamenta of the Trent in 
Notts., and a large colony was discovered by Mr. C. P. 
Cambridge at Morden in Dorset, in 1889, and another 
colony near the same place in 1890. In the Dorset 
locality it was found on the stems of bulrushes, thus 
bearing out Jefireys’ idea (B.C., vol. 1, —p. 256) that 
should be looked for in marshy places. 
It has been recorded for Otterbourne, Hants.; Hitchen 
and Rye House, Herts. 
Var. I. Zelljeborgit ( West/.). Rather less swollen than
